Aijiren Volatile Organic Chemical sampling vial closed-top cap

Passive air sampling for semi-volatile organic chemicals

A distinct set of PASs has been developed for semi-volatile organic chemicals (SVOCs). The term SVOCs comprises organic molecules that can occur to a significant extent in both the gas-phase and condensed phases, which corresponds to the vapour pressure range of approx. 10 −1 to 10 −6 Pa. The group of SVOCs comprises a large number of

i. Travel Blanks should be used in Volatile Organic Chemical sampling or other sampling that the laboratory suggests should have a travel blank. Travel Blanks are to be kept together with the field samples, with the custody seals intact, to determine whether samples are contaminated during the transport process. ii.

WATER SAMPLING & TESTING Introduction - Michigan

Volatile Organic (36VO) • Do not collect a sample where chemical odors are detected. Collect the sample in a location free of organic chemical vapors (gasoline, fuel oil, paint, paint thinner, and solvents). • Do not touch the inside of the cap, septum or bottle. Do not rinse the bottle or allow the water to overflow.

Volatile Organic Compounds (VOCs) as Environmental Pollutants

Dec 13, 2021 · Volatile organic compounds (VOCs) are organic chemical compounds found in various products that easily vaporise and reach in the environment under normal conditions. VOCs have increased volatility, mobility and they are resistant to degradation, being able to be transported to long distances in the environment [ 1 ].

Volatile identification was performed using Mass Hunter (Qualitative Analysis v10, Aijiren Technologies Inc.) by comparing their retention index (RI) and mass spectrum with the NIST 2020 V2.20 (National Institute of Standards and Technology, United States) which consists of more than 300,000 spectra representing more than 300,000 unique compounds.

The vial was then closed with a cap containing polytetrafluoroethylene (PTFE)-coated rubber septum and kept at 50 °C for 60 min. Headspace gas-chromatographic analysis was performed by manually injecting 1.0 mL of the vial headspace from each sample by means of a 1.5-mL Hamilton gas-tight syringe (temperature kept at 50 °C).
