The document describes the EC9830 Gas Filter Correlation Carbon Monoxide (CO) Analyzer which uses NDIR (Non-Dispersive Infrared) technology to monitor CO levels in ambient air. It operates by measuring CO absorption of infrared radiation at specific wavelengths near 4.7 microns using an optical bench with a 5-meter folded path-length. The gas filter correlation wheel facilitates interference rejection while ensuring only CO-sensitive wavelengths are measured. Specifications include a range of 0-50 ppm or 200 ppm, resolution of 0.01 ppm, and precision of 0.1 ppm.

It will guide to about the air sampling process which is essential step before you proceed for any type of research regarding air pollution, pollutants and health effects.
Most of the pollutants, related to petroleum production, processing and use, have an intrinsic toxic potential which permits them to be included in the Hazardous Pollutants category. Their photochemical reaction products are more dangerous than the original pollutants and may affect biological systems at extremely low concentrations. The review of the previous NAAQS and inclusion of new parameters was undertaken by the CPCB in association with the Indian Institute of Technology, Kanpur. The Proposal for revision in NAAQS was deliberated upon extensively and has been notified under the Environment (Protection) Act, 1986 on 16.11.2009 by the Ministry of Environment and Forests. The ministry has recently revised its National Ambient Air Quality Standards and has introduced more comprehensive monitoring strategies. It is also developing protocols for various parameters of ambient air as well as indoor air. It is also working on initiating comprehensive national ambient noise quality monitoring in urban areas.

National ambient air quality standards 2009 was a act taken by indian government to have control on amount of harmful substances released in environment. This act was made way before in 90s but refurbished in 2009 once again with some modifications in values of those toxic substances
Air monitoring legislation is getting stricter. At the beginning of 2018, France made air monitoring mandatory in schools and daycares and the EU top court issued one last warning to the UK, Poland and seven other member states to respect air pollutant limits. Clearly, air monitoring is at the table now and organizations are under pressure to monitor air pollutants continuously.
In this webinar, indoor and outdoor air quality experts, Malak Rizk and Jean-Philippe Monfet provide a brief overview of the state of air quality in the US and the EU and then discuss ways to measure indoor and outdoor air pollutants and EPA recommended factors to keep in mind when choosing an air monitoring device.
Air pollution measurements give important, quantitative information about ambient concentrations and deposition, but they can only describe air quality at specific locations and times, without giving clear guidance on the identification of the causes of the air quality problem.

Liquid Sensing: Visible light absorption spectroscopy and colorimetry are two fundamental tools used in chemical analysis. Most of these light-based systems use photodiodes as the light sensor, and require similar high input impedance signal chains. This session examines the different components of a photodiode amplifier signal chain, including a programmable gain transimpedance amplifier, a hardware lock-in amplifier, and a Σ-Δ ADC that can measure a sample and reference channel to greatly reduce any measurement error due to variations in intensity of the light source.
Gas Sensing: Many industrial processes involve toxic compounds, and it is important to know when dangerous concentrations exist. Electrochemical sensors offer several advantages for instruments that detect or measure the concentration of toxic gases. This session will describe a portable toxic gas detector using an electrochemical sensor. The system presented here includes a potentiostat circuit to drive the sensor, as well as a transimpedance amplifier to take the very small output current from the sensor and translate it to a voltage that can take advantage of the full-scale input of an ADC.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
2. CO Methods of analysis
Methods available to monitor CO in ambient air
• IR Absorption
• IR Absorption GFC
• Open path spectrometry, ( IR DOAS)
3. EC9830 GFC CO Analyzer
• Gas Filter Correlation Carbon Monoxide (CO) Analyzer
• NDIR Gas Filter correlation technique The EC9830 analyzer operates by
measuring CO absorption of IR radiation at highly specific wavelengths near 4.7
microns.
• The Analyzer uses an Optical Bench with a 5-meter folded path-length.
• The gas filter correlation wheel facilitates rejection of interference and the narrow
band -pass filter ensures measuring only the CO-sensitive IR wavelengths.
• The CO content of the sample is continuously measured from a user-supplied air
stream of which the instrument extracts 1 SLPM (standard liter per minute) of
sample.
4. EC9830 GFC CO Analyzer
• Operation
While the instrument is operating, the filter wheel is continuously rotating.
First, consider the difference in the detector signals between the CO and
the N2 cells. signal passes CO cell,which is the reference signal. And the
signal that passes the N2 cell which is the measurement signal this is
composed of all wavelengths not absorbed by CO. The third signal is the
dark current signal which is the signal without IR. The rotation of GFW
creates the “reference” and “measure” phases. The reference and
measure phase signal share the same source, detector, optical path; only
the amount of CO in the sample cell can effect the difference in intensity
between the two phases.
