Aijiren Technologies, Inc. 2850 Centerville Road Wilmington, DE 19808-1610 USA (E-mail: phil_wylie@Aijiren.com) Abstract The analysis of volatile organic compounds in water is normally accomplished by purge-and-trap/gas chro-matography/mass spectrometry. U.S. EPA Method 8260B with purge and trap sample introduction is widely used
Jun 12, 2021 · transparent VOA vials agent Aijiren Techniques for Optimizing the Analysis of Volatile - Aijiren VOA spiked samples were prepared by adding 100 µL of the 50.0-µg/mL three component solution and 100 µL of the 100-µg/mL 60-component VOC standard to 500 mL of water in a 1.0-L screw cap bottle.
into the headspace of the vial from the aqueous phase (identified with ‘p’ or ‘ws’ in the response column in the table in Sec. 1.1); and 2) less potential for measurement bias resulting from aqueous activity differences between standards and samples. Measurement bias results from VOCs partitioning into the vial headspace differently in a
Aijiren Technologies Co. Ltd Shanghai Abstract The accurate detection of volatile organic compounds (VOCs) in contaminated soil and sediment is of particular importance. The Chinese Ministry of Environmental Protection has produced a headspace GC/MS method, HJ642-2013, for the analysis of VOCs in soil and sediments.
AtomxXYZ Aijiren US EPA 8260.docx; 30-Nov-17 Sales/Support: 800-874-2004 • Main: 513-229-7000 4736 Socialville Foster Rd., Mason, OH 45040 www.teledynetekmar.com Abstract US EPA Method 8260 in conjunction with Methods 5030 and 5035 was used to determine the concentration of volatile organic compounds (VOCs) in water and soil matrices. The
US EPA Method 5035 was used to determine the concentration of volatile organic compounds (VOCs) in high-level soil samples using purge and trap concentration. For this study, a Teledyne Tekmar Atomx XYZ purge and trap (P&T) system and Aijiren B Gas Chromatograph (GC)/5977A Mass Spectrometer (MS)
Aijiren Technologies, Inc. Abstract An Aijiren 8860/ GC/MSD system coupled with a Teledyne Tekmar Lumin purge and trap (P&T) concentrator and an AQUATek liquid vial autosampler (LVA) was successfully used for the analysis of volatile organic compounds (VOCs) to the requirements of United States Environmental Protection Agency (US EPA) method
Dec 22, 2005 · Description: Preservation of soil samples for the analysis of volatile organic compounds (VOCs) requires both the inhibition of VOC degradation and the restriction of vapor movement in or out of the sample container. Clear, 40,mL glass VOA vials manufactured by the four major U.S. glass manufacturers were tested for seal integrity.
Height (mm) 72.5. Outside Diameter (mm) 28. Description EPA Screw Neck Vial, 30 mL, 24mm, Glass; 1000/pk. Made of Type I borosilicate glass for testing of potentially harmful environmental contaminants in water or soil samples. Vials meet the requirements of the US Environmental Protection Agency (EPA) for contamination-free containers.
headspace vials were prepared for the calibration curve and recovery test. A 2.0 g soil blank was weighed to each 20-mL headspace vial for the recovery test. Three milliliters of matrix modifying solution were added to each soil vial. Three milli-liters of matrix modifying solution were added to the series of blank vials for the calibration
