VOCs are often associated with air pollution, however they can also contaminate water through direct discharges or atmospheric deposition, posing potential risks to human health and the environment. In a series of application notes, insights into various approaches for VOC analysis in drinking water as well as ground and wastewater samples, aiming to ensure water safety and regulatory compliance, are provided.

1. Analysis of VOCs in drinking water according to U.S. EPA Method 524.4

Explore an analytical method that meets the requirements outlined in US EPA Method 524.4 for the quantitation of volatile organic compounds (VOCs) in drinking water, using the Teledyne Tekmar Atomx XYZ purge and trap (P&T) system along with a Thermo Scientific™ ISQ™ 7610 Single Quadrupole MS system coupled with a Thermo Scientific™ TRACE™ 1610 Gas Chromatograph (GC) and Thermo Scientific™ Chromeleon™ Chromatography Data System (CDS).

4. Reducing the helium consumption for analysis of VOCs in accordance with EPA Method 8260D without compromising performance using HeSaver-H2Safer technology

Understand the significance of VOCs. The method of choice for analyzing VOCs involves gas chromatography coupled with single quadrupole mass spectrometry using Purge and Trap (P&T) sampling. The HeSaver-H2Safer™ technology offers a solution by significantly reducing helium consumption without compromising performance. The application of this technology in conjunction with gas chromatography and mass spectrometry for the analysis of water and soil samples according to EPA Method 8260D is detailed.

5. In-Tube Extraction Dynamic Headspace (ITEX-DHS) sampling technique coupled to GC-MS for sensitive determination of odorants in water

Explore a study that aims to demonstrate the applicability of the In-Tube Extraction Dynamic Headspace (ITEX-DHS) technique coupled to gas chromatography-mass spectrometry (GC-MS) for the determination of trace-level odorants in water. Through dynamic headspace enrichment achieved by means of the ITEX technique, the target analytes isoborneol (IB), 2-methyl-isoborneol (2-MIB), 2,4,6-trichloroanisole (2,4,6-TCA), and geosmin were extracted and pre-concentrated to reach sub-ppt level limits of detection (LOD).

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.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.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Volatile Organic Compounds (VOCs)Volatile organic compounds (VOCs) are chemicals that have a low boiling point. Some VOCs are harmful to human health, whereas others can be used to determine the shelf-life of foods samples. Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).
