Analysis was performed by solid phase micro-extraction technique with a μm polydimethylsiloxane fibre using gas chromatography with mass spectrometry detection to analyse 54 volatile organic compounds (VOCs) of different chemical families in drinking water. The concentration of VOCs ranged from undetectable to μg/ by: for screening soil and ground-water samples in the field during the water-resources investigations at WPAFB. Presented in case-study form, this report is intended as guidance for investigators who may need a rapid semi-quantitative determination of the concen tration of Author: James M. Parnell.
Essentially no volatile organic compound (VOC) memory (i.e., adsorption carryover by the device) was measured at the µg/m 3 level. The data suggest that the device can be used successfully for organic compounds with volatilities greater than that of by: Department of Analytical Chemistry, University of A Coruña, Zapateira s/n, E A Coruña, Spain Abstract. This work proposes a method for quantifying volatile organic compounds (VOCs) in coal, fly ash and slag, coming from coal-fired power stations, using direct thermal desorption coupled with gas chromatography (GC) and mass spectrometryFile Size: 87KB.
An analysis method for volatile organic compounds in blood based on purge-and-trap extraction coupled with gas chromatography-Fourier transform infrared spectroscopy (GC-FTIR) was developed. The sample volume was 5 mL, and the internal standard was diethyl by: The analysis of volatile organic compounds (VOCs) is one of the most important topics under discussion at Pittcon in Chicago. The accurate measurement of VOCs enters numerous scientific arenas from the detection of VOCs as biological markers for cancer cells (health monitoring chemical fingerprint)  to monitoring the environment for Author: Pittcon.

Geological Survey Open-File Report. The U.S. EPA () has defined compounds as chemical indicators of organic pollution in water. These indicators are divided into two groups: 30 purgeable organic compounds and 84 semi-volatile and nonvolatile organic compounds.
The latter compounds may be analyzed via liquid/liquid extraction and subsequent direct injection into a GC/MS. When referencing a book, proceedings, report, or paper in a collection, please remember to provide the city and publisher of the citation.
When referencing a personal communication, always provide the date and city of the communication (written or interview). The analytical system is demonstrated to be free from interferences under conditions of the analysis by analyzing reagent water blanks initially and with each sample batch (samples analyzed on the same hour shift), as described in Section Samples can be contaminated by diffusion of volatile organic compounds through the bottle seal.
The series includes several sample preparation methods (purge-and-trap, extraction, azeotropic distillation, vacuum distillation, dilution, headspace, etc.) that introduce volatile organic compounds into a detection device for various matrices (e.g., aqueous, soil/sediment, solid.
This practice provides a general procedure for the SPME of volatile organic compounds from the headspace of an aqueous matrix. Absorbent extraction is used as the initial step in the extraction of organic constituents for the purpose of screening and subsequently estimating the concentration of the volatile organic components found in water samples.

The use of the headspace technique (particularly in its dynamic modes) for sampling volatile compounds in solids has by now reached most fields of industrial, environmental and social interest.

Soil samples also can be analyzed in a similar, but less quantitative, manner. To analyze a sample using a Photovac gas chromatograph, a small volume of the headspace is injected through a gas-tight Cited by: 6. This is particularly true for volatile organic compounds (VOCS) which can easily volatilize and/or degrade during sample storage.
Recognizing this, regulatory agencies require water samples be collected in vials without headspace and stored at 4 degrees C, and that analyses be conducted within 14 days, even if samples are acid-preserved. environmental protection agency national enforcement investigations center p.o.

Key words: volatile organic compounds, internal standards, bias, biota, soil, water, analyses. Introduction. Volatile organic compounds (VOCs) make up a major group of compounds routinely monitored as environmental contaminants.
RCRA SW Method C is the determinative protocol of choice with a pre-concentration protocol such as headspaceFile Size: KB. This guide covers the identification and quantitation of organic compounds by gas chromatography/mass spectrometry (GC-MS) (electron impact) that are present or extracted from water and are capable of passing through a gas chromatograph without alteration.
This guide can be used to provide tentative identifications of volatile and semi-volatile organics, but is restricted to (a). As the EPA-designated reference laboratory for NY State, the Environmental Organic Chemical Analysis Laboratory analyzes water, soil, and air samples submitted by state agencies and local health departments for a variety of organic environmental contaminants.
Analysis/tests routinely performed: Volatile organic compounds in potable water. Biological terminal metabolites are volatile organic compounds (VOCs) with strong volatility, containing important bio-information related with biological metabolism.
As a crucial research precondition, analytical methodology for biological VOCs has attracted much attention to achieve the adequate composition information of biological VOCs at different physiological status and metabolism phases.
