Thermal desorption applications guide: Environmental monitoring
15 Jun 2023This application note from Markes International emphasizes the importance of monitoring organic chemicals in the air, regardless of whether they originate from human activities or natural sources.This monitoring is crucial for evaluating their impact on human health and their contribution to global climate. The focus of this note is to illustrate how thermal desorption (TD) can be utilized to monitor compounds in various scenarios within the field of environmental monitoring. The primary sampling techniques discussed include passive (diffusive) sampling of air onto sorbent tubes, pumped (active) sampling of air onto sorbent tubes, online monitoring of air/gas streams, and pre-concentration of air samples collected in canisters.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Environmental AnalysisEnvironmental analysis describes a variety of tests that determine the effect of chemicals, processes and particulates such as persistent organic pollutants (POPs) have on the environment.Organic CompoundsOrganic compounds are carbon-based molecules that form the building blocks of life. These include hydrocarbons, lipids, proteins, and nucleic acids. Understanding organic compounds is crucial in chemistry, biochemistry, and pharmacology.
