Validation of New VPH GC/MS Method using Multi-Matrix Purge and Trap Sample Prep System
22 Jul 2015The previous method for Volatile Petroleum Hydrocarbon (VPH) determination required both Flame Ionization (FID) and Photoionization (PID) detectors, as developed by The Massachusetts Department of Environmental Protection (MassDEP). This new method utilizes Mass Spectrometry, through Teledyne Tekmar’s Purge and Trap technology, which allows for the determination of volatile organic compounds (VOCs) at low concentration levels with precision and accuracy. This application note aims to validate this new method of VPH analysis.

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. PetroleumSoil TestingSoil testing helps determine the nutrient content, pH level, and other factors affecting soil health. This information is critical for agriculture, environmental science, and land management.
