A Rabbit Model for Assessment of Volatile Metabolite

2017/01/01 · The syringe needle was inserted through the cap septum and 500 µL of headspace was inspired. Upon sampling, the syringe content was injected into the GC inlet, and the syringe was purged with helium carrier gas for 30 sec to prevent carryover for the next injection. The syringe temperature was maintained at 80 °C during sampling to avoid carryover.

Volatile chemical products emerging as largest

2018/02/16 · Transport-derived emissions of volatile organic compounds (VOCs) have decreased owing to stricter controls on air pollution. This means that the relative importance of chemicals in pesticides, coatings, printing inks, adhesives, cleaning agents, and personal care products has increased.
