Analysis of Long-chain Petroleum Hydrocarbons and VOCs in Soil by GC-MS

Overview
Presenters

In this webinar, we focus on the analysis of organic contaminants in soil using gas chromatography-mass spectrometry (GC-MS) methods. This webinar will highlight two different approaches:

Nitric oxide ionization spectroscopy evaluation (NOISE) − a non-traditional mass spectrometry method for hydrocarbon typing.
- NOISE enables structural determination of components in process streams, by carbon number and degree of unsaturation. The benchmark technique for hydrocarbon typing assists scientists in identifying oil spills and contamination in the environment, optimizing hydrotreaters and evaluating unit performance, and makes the most of new crude oil slates.
Methods for sample collection and analysis of soils and solid wastes for volatile organic compounds (VOCs) follow established outline procedures, e.g., EPA 5035A.
- This procedure is required for analytical methods using Purge & Trap analysis (8021, 8015 and 8260) and are standard in many contract Environmental Laboratories. Soil matrixes are performed on two ranges: low level and high level using Purge and Trap sample concentration and GC-MS detection. Data will be shared showing expected calibration ranges and quality control to meet Method 8260.

Terry Jeffers, Senior GCMS Application Chemist, Thermo Fisher Scientific

Terry has 28 years’ experience in the Environmental GC, GC-MS applications. Terry spent 5 years with the Florida Department of Health as a bench chemist with a focus on analysis of VOC’s in air (TO-14), water (Method 524.2) and soil (Method 8260). Terry spent 10 years at Teledyne Tekmar, Purge and Trap manufacture as a Global Training / Application Support Specialist. Presently, Terry works for Thermo Fisher Scientific as Senior GC-MS Application Chemist focused on promulgated GC-MS EPA methodologies for Volatile and Semi Volatile analysis.
