This type of analysis is concerned with determining the exact amount or concentration of a particular chemical substance in a sample.

1. Analytical-Chemistry Types
Analytical chemistry is a branch of chemistry that focuses on the identification and quantification of
chemical substances, as well as the analysis of complex mixtures of chemicals. There are several types of
analytical chemistry methods and techniques used to achieve these goals. Here are some common types
of analytical chemistry
Quantitative Analysis:
This type of analysis is concerned with determining the exact amount or concentration of a particular
chemical substance in a sample. Common techniques for quantitative analysis include titration,
gravimetric analysis, and various spectroscopic methods.
Qualitative Analysis
Qualitative analysis is used to identify the presence or absence of specific components in a sample.
Methods like chromatography, mass spectrometry, and infrared spectroscopy are often used for
qualitative analysis.
Instrumental Analysis
This category involves the use of advanced instruments and equipment to perform chemical analysis.
Techniques such as gas chromatography (GC), high-performance liquid chromatography (HPLC), atomic
absorption spectroscopy (AAS), and nuclear magnetic resonance (NMR) fall under this category.
Separation Techniques
Analytical chemistry often involves separating a mixture into its individual components for analysis.
Common separation techniques include liquid chromatography, gas chromatography, electrophoresis,
and distillation.
Spectroscopy
Spectroscopic methods analyze the interaction of matter with electromagnetic radiation. This can
involve techniques like UV-Visible spectroscopy, infrared spectroscopy, nuclear magnetic resonance
(NMR) spectroscopy, and mass spectrometry.
Electroanalytical Chemistry
This type of analytical chemistry involves the use of electrochemical techniques to measure and analyze
chemical species. Methods include voltammetry, potentiostatic/galvanostatic methods, and cyclic
voltammetry.
Thermal Analysis

2. Thermal analysis techniques are used to study how a substance's properties change with temperature.
This includes methods like differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
Chemical Sensors and Biosensors:
Analytical chemistry also encompasses the development and use of chemical sensors and biosensors for
detecting specific analytes. These sensors are often used in environmental monitoring, healthcare, and
industry.
Mass Spectrometry
Mass spectrometry is a versatile technique that measures the mass-to-charge ratio of ions. It is used for
both qualitative and quantitative analysis and can be coupled with other separation techniques.
Environmental Analysis
This subfield focuses on the analysis of environmental samples, including air, water, and soil, to assess
the presence of pollutants and contaminants. Methods may include gas chromatography-mass
spectrometry (GC-MS) for detecting organic pollutants and inductively coupled plasma-mass
spectrometry (ICP-MS) for trace metal analysis.
Food and Beverage Analysis
Analytical chemistry is crucial for ensuring the safety and quality of food and beverages. Techniques like
high-performance liquid chromatography (HPLC) and polymerase chain reaction (PCR) are commonly
used in this context.
Forensic Chemistry
In forensic science, analytical chemistry is used to analyze evidence such as drugs, toxic substances, and
trace materials to assist in criminal investigations
These are just a few of the many types of analytical chemistry, and each type has its own set of
techniques and applications tailored to specific analytical needs.
