Jan 27, 2022 · The World Health Organization classifies organic compounds with a boiling point of 323.15–533.15 K as volatile organic compounds. Ethylbenzene, a typical volatile organic compound, has been widely studied in environmental science areas such as water [ 17 ] and gasoline [ 18 ], focusing on the determination at the trace level in the matrix.

CD-ROM 0031-1 Revision 0 December 1996 METHOD 0031 SAMPLING METHOD FOR VOLATILE ORGANIC COMPOUNDS (SMVOC) 1.0 SCOPE AND APPLICATION 1.1 Method 0031 is used to determine volatile organic compounds in gaseous em issions from a wide variety of stationary sources including hazardous waste incinerators. The following compounds may be determined by this method: Compound Boiling Point ( EC) CAS No.a.
Precleaned volatile organic analyte sampling vials are cleaned and assembled before delivery, and are lot traceable for guaranteed quality. Screw-thread or vial format Clear or amber color Glass fabrication 24 mm orifice Volume capacity ranges from 20 to 60 ml depending on model.
Volatile Organic Chemicals. Samples collected for Volatile Organic Chemical (VOC) analysis need to be collected in pre-cleaned, pre-preserved 40 mL vials that are available at the laboratory. These vials contain hydrochloric acid (HCl) and therefore should be handled with caution. Take care not to touch or otherwise contaminate the inside of
Sampling Location (Sampling siting plan approved by local health department in sanitary survey) Laboratory Name Phone Volatile Organic Chemicals – General Information Volatile organic chemicals include components of petroleum based products and industrial solvents and chemicals.
1.1 This method describes equilibrium-based static headspace preparation of volatile organic compounds (VOCs) in soil/sediment, solid waste, aqueous and water-miscible liquid samples for determination by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS). This method is applicable to a wide range of organic compounds that

The stock standard is prepared in PPG or other low vapor pressure solvent. The working standard is prepared by spiking a volume of the stock standard into reagent water. 7.5.2 Stock standard The stock standard should be prepared such that a 1- to 2-µL volume of the working standard (Sec. 7.5.3) added to 10 mL of reagent water and 5 g of
This paper focuses on the distribution of volatile organic compounds (VOCs) in the surface water, soil, and groundwater within a chemical industry park in Eastern China. At least one VOC was detected in each of the 20 sampling sites, and the maximum number of VOCs detected in the surface water, groundwater, and soil were 13, 16, and 14
Among thousands of organic compounds present in environmental matrices, halocarbons, i.e., organic chemical molecules containing at least a chemical covalent bond between a carbon atom and one (or more) halogen atoms [11,12], are very toxic (and some of them also carcinogenic), the most common are fluorine, chlorine, bromine and iodine [13,14
