Detection of petroleum-contaminated soils using Equilibrium Headspace and Methanol Extraction
Petroleum spills and leaking underground storage tanks comprise a significant portion of remediation projects. Soil removal and disposal determined based on the contaminants and concentrations present. Specific target analytes are associated with this type of contamination. A number of these compounds are classified as volatile organics and are used to assess the severity of the contamination, ...

Evaluation of gas chromatography mass spectrometry and pattern recognition for the identification of bladder cancer from urine headspace
Previous studies have indicated that volatile organic compounds specific to bladder cancer may exist in urine headspace, raising the possibility that they may be of diagnostic value for this particular cancer. To further examine this hypothesis, urine samples were collected from patients diagnosed with either bladder cancer or a non-cancerous urological disease/infection, and from healthy ...

Validation of New VPH GC/MS Method using Multi-Matrix Purge and Trap Sample Prep System
Abstract The Massachusetts Department of Environmental Protection (MassDEP) developed the “Method for the Determination of Volatile Petroleum Hydrocarbons (VPH) by Gas Chromatography/ Mass Spectrometry” to measure the collective concentrations of volatile aliphatic and aromatic petroleum hydrocarbons in aqueous and soil/sediment matrices1. The previous method for VPH determination ...
