Nitrate adsorption and desorption during biological ion

Mar 15, 2022 · At both sampling periods, gas volumes were measured in the headspace of each bottle using a frictionless borosilicate glass syringe fixed in a stationary horizontal position. After recording the gas measurement, the syringe was compressed to force gas back into the serum vials, with small amounts lost due to the volume of the syringe needle.

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
