Chromatography is a biophysical technique that enables separation, identification and purification of the components of a mixture.
The separation is based on the differential partitioning between the mobile phase and the stationary phase.
Mobile phase – solvent, which move through or over the stationary phase.
Stationary phase – either is solid with high surface area or liquid coated on to a solid; stay still.
Column chromatography is a method for separating mixtures of substances in which a liquid or gaseous solution of mixture (mobile phase) is caused to flow through a tube packed with a finely divided solid (stationary phase ), may be coated with absorbent liquid or through a long capillary tube bearing a thin film of adsorbent liquid.The components of the mixture separates based on the adsorption of the solutes of the solution.
Gas chromatography is technique used to separate and purify individual components from mixture of compounds that can be vaporized. The mobile phase is a gas and the components are separated as vapor. The separation is carried out in a column.
High Performance Liquid Chromatography or high pressure liquid chromatography relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid absorbent material.
Thin layer chromatography is a solid liquid adsorption chromatography. The stationary phase is applied as thin layer on a solid support plate with a liquid mobile phase.
Paper chromatography is analytical method used to separate colored chemicals or substances using a paper as the stationary phase. In this, a thick filter paper comprised the support, and water drops settled in its pores made up the stationary liquid phase. It is a liquid – liquid chromatography.

Chromatography is a technique used to separate mixtures by exploiting differences in how components interact with a stationary and mobile phase. There are four main types: paper chromatography uses paper as the stationary phase; thin-layer chromatography uses silica gel or other adsorbents; gas chromatography uses an inert solid and gas as phases to separate volatile compounds; and high performance liquid chromatography forces liquid samples through columns under high pressure for improved separation. Chromatography has many applications across fields like analyzing plant pigments, detecting pesticides, identifying pollutants, and aiding forensic investigations.

ntroduction to Chromatography
Chromatography is a powerful analytical technique used to separate, identify, and quantify the components of a complex mixture. This versatile method is widely used across numerous scientific fields, including chemistry, biology, environmental science, and forensics. At its core, chromatography relies on the differential distribution of analytes between a stationary phase and a mobile phase, allowing for the efficient separation and precise analysis of even the most intricate samples.
The underlying principle of chromatography is the difference in the affinity of various compounds for the stationary and mobile phases. As the sample is introduced into the system, the individual components are carried by the mobile phase and interact with the stationary phase, resulting in their differential migration and separation. This process enables scientists to not only identify the presence of specific compounds but also measure their relative concentrations with remarkable accuracy.
History and Development of Chromatography
The origins of chromatography can be traced back to the early 20th century, when the Russian botanist Mikhail Tsvet first introduced the concept in 1903. Tsvet used a glass column packed with calcium carbonate to separate plant pigments, such as chlorophyll and carotenoids, by their differential adsorption onto the stationary phase. This pioneering work laid the foundation for the development of various chromatographic techniques that would revolutionize the field of analytical chemistry.
In the following decades, chromatography continued to evolve, with scientists exploring different stationary phases, mobile phases, and separation mechanisms. The introduction of paper chromatography by Archer John Porter Martin and Richard Laurence Millington Synge in the 1940s, and the subsequent development of thin-layer chromatography (TLC) and gas chromatography (GC) in the 1950s, further expanded the capabilities of chromatographic analysis. These techniques allowed for the separation and identification of an increasingly diverse range of compounds, from small organic molecules to complex biomolecules.
The 1960s and 1970s witnessed a significant breakthrough with the introduction of high-performance liquid chromatography (HPLC), which provided higher resolution, sensitivity, and speed compared to earlier chromatographic methods. The continuous advancements in column technology, detection syst

It provides details on the principles, instrumentation, applications, and limitations of these techniques. The key applications mentioned are detection of impurities, structure elucidation, quantitative and qualitative analysis, and studying chemical kinetics, drugs, and metals in samples.
Electrophoresis amirtham
1. Electrophoresis is a physical method used to separate charged compounds by using an electric field to migrate them through a conductive medium like a gel or paper.
2. The rate at which compounds migrate depends on their charge, size, shape, and the applied electric current. There are different types of electrophoresis that use different conductive media like paper, cellulose, or polyacrylamide gels.
3. Electrophoresis has many applications including DNA sequencing, medical research, and protein purification and is used in various industries like food to separate molecules like amino acids, proteins, and nucleic acids.
Crystallography amirtham
Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. It began with the discovery of X-rays by Röntgen in 1901. There are 7 crystal systems that describe the symmetry and geometry of unit cells, which is the smallest repeating unit that makes up the crystal structure. X-ray crystallography techniques like Bragg's law and diffraction patterns are used to determine the positions of atoms within crystals by measuring the angles and intensities of X-rays scattered after striking the crystal.
Chromatography amirtham
Chromatography is a laboratory technique used to separate the components or substances within mixtures. It works by distributing the components of a mixture between two phases, one stationary and one mobile, so that each component moves through the phases at a different rate and can thus be separated and analyzed. The basic principle is that between a stationary phase and a mobile phase, the distribution of the sample depends on differential partitioning between the phases and that different components of the mixture are partitioned in different ways.
Centrifugation amirtham
A centrifuge uses centrifugal force to separate fluids or particles of different densities. It works by applying centrifugal acceleration, which causes denser particles to move outward in the radial direction while less dense particles move to the center. There are different types of rotors and centrifuges that separate particles based on properties like size, shape, density or sedimentation rate. Ultracentrifuges spin at very high speeds of over 100,000g to separate small particles like organelles, viruses and macromolecules.
Calorimeter
Circular dichroism (CD) is a type of absorption spectroscopy that provides structural information about biological macromolecules. CD measures the difference in absorption of left and right-handed circularly polarized light. It is used to determine protein structures, observe structural changes from factors like pH and heat, study protein folding and unfolding, monitor ligand binding, and analyze the structures of nucleic acids, polysaccharides, peptides, and other small molecules.
C dna and genomic libraries copy
This document discusses cDNA and genomic libraries. It defines cDNA and genomic libraries and explains their key differences. A cDNA library contains only complementary DNA molecules synthesized from mRNA in a cell and represents the genes expressed in that cell. Genomic libraries for prokaryotes are easier to make and contain all genome sequences since prokaryotic mRNA is unstable. cDNA libraries are useful for eukaryotic gene analysis as they contain condensed protein-encoded genes without introns. The document also provides details on the construction, screening, and uses of cDNA and genomic libraries.

They range in size from 150-230kbp and contain T-DNA segments and vir genes. Ti plasmids are divided into octopine and nopaline types based on the type of opine synthesized in infected plant cells. Ri plasmids found in Agrobacterium rhizogenes are analogous to Ti plasmids and can also transfer DNA segments to plant cells, making them useful for plant genetic engineering. Several animal viruses can also act as viral vectors to transfer foreign genes to animal cells, including SV40, baculoviruses, retro
Presentation
Gene silencing is a process that downregulates gene expression without altering the DNA sequence. It can occur at the transcriptional or post-transcriptional level through various methods like RNA interference, DNA methylation, and histone modifications. Gene silencing is important for normal development and cellular differentiation, but can also contribute to diseases if aberrantly silencing critical genes. It is currently being explored as a tool for crop improvement, drug discovery, and antiviral therapies.
Cloning pcr
This document discusses PCR cloning and various applications of PCR. It provides details on:
1. PCR cloning allows amplification of DNA fragments and vectors without restriction enzymes, requiring only small amounts of DNA.
2. PCR has numerous applications including gene cloning, paternity testing, and mutation detection for inherited diseases.
3. Key aspects of PCR include its three main stages - denaturation, annealing of primers, and extension. Proofreading enzymes play an important role by identifying and removing mismatched bases to ensure high fidelity DNA replication.
Labelling of dna
This document discusses nucleic acid probes and their use in hybridization experiments. It notes that probes are short sequences of nucleotides that bind to specific target sequences. The degree of homology between the probe and target determines how stable the hybridization is. Probes can range in size from 10 to over 10,000 nucleotide bases, with most common probes being 14 to 40 bases. Short probes hybridize quickly but have less specificity, while longer probes hybridize more stably. The document then describes different methods for labeling probes, including nick translation, primer extension, RNA polymerase transcription, end-labeling, and direct labeling. It also discusses factors that affect probe specificity and hybridization conditions.
Spectroscopy
Spectroscopy is the study of spectra, or the interaction between matter and electromagnetic radiation. There are several types of spectroscopy including continuous, absorption, and emission spectroscopy. Absorption spectroscopy analyzes the absorption spectra of elements to deduce their presence in distant objects like stars. Emission spectroscopy identifies elements by comparing their emission spectra produced during energy emission to their known absorption spectra. Spectroscopy has many applications including identifying the composition of planets and using fluorescence spectroscopy to label and observe multiple activities in living cells at once.
Electrophoresis wps office
Electrophoresis is a technique used to separate molecules like DNA, RNA, and proteins based on their size and charge. It involves placing the molecules in an electric field, which causes them to migrate at different rates depending on their charge - nucleic acids migrate toward the anode due to their negative phosphate backbone, while proteins can migrate either way depending on their overall charge. Different methods like paper, gel, polyacrylamide gel, and agarose gel electrophoresis are used to separate molecules depending on their size, with gels allowing for better resolution of larger molecules. Protein electrophoresis specifically analyzes protein mixtures by separating the proteins based on factors like their length, conformation and charge.
Crystallography
- Crystallography is the study of crystal shapes and symmetry based on how atoms combine to form geometric patterns on the smallest scale.
- There are 5 main symmetry functions that determine the 32 possible crystal classes: axis of rotation, mirror plane, center of symmetry, axis of rotoinversion, and crystal forms.
- Crystal forms include pinacoids, prisms, pyramids, dipyramids, and others that are characteristic of specific crystal classes and systems. Identifying crystal forms is important for determining the crystal's symmetry and class.
Centrifugation
The document discusses centrifugation and its applications in bi separations. Centrifugation uses centrifugal force generated by high-speed rotation to separate particles, cells, organelles, and other biological materials based on density. It describes how mitochondria are isolated from mouse liver tissue using differential centrifugation at increasing speeds and centrifugation in a Percoll density gradient to purify the mitochondria. Safety considerations for operating centrifuges to avoid rotor failure and aerosol release are also covered.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

It is used in scientific studies to identify unknown organic and inorganic compounds from a mixture.
- 8. Thin-layer chromatography (TLC) Thin-layer chromatography (TLC) is achromatography technique used to separate non-volatile mixtures. ... The mobile phase has different properties from the stationary phase. For example, with silica gel, a very polar substance, non-polar mobile phases such as heptane are used. Chromatography works on the principle that different compounds will have different solubilities and adsorption to the two phases between which they are to be partitioned. Thin Layer Chromatography (TLC) is a solid-liquid technique in which the two phases are a solid (stationary phase) and a liquid (moving phase). used separation technique used in life sciences and chemistry studies. It is easy, cheap and gives rapid results. It is used to isolate and analyse mixtures of compounds.
- 10. Gas chromatography Gas chromatography is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture Principle of gas chromatography: The sample solution injected into the instrument enters agas stream which transports the sample into a separation tube known as the "column." (Helium or nitrogen is used as the so-called carrier gas.) The various components are separated inside the column. Two types of gas chromatography are encountered: gas-solid chromatography (GSC) an d gas-liquid chromatography (GLC)
- 12. Liquid chromatography Liquid chromatography (LC) is a separation technique in which the mobile phase is a liquid, where sample ions or molecules are dissolved. It is carried out either in a column or a plane. used to separate proteins, nucleic acids, or small molecules in complex mixtures. Liquid chromatography (LC) separates molecules in a liquid mobile phase using a solid stationary phase. Liquid chromatography can be used for analytical or preparative applications.
