Volatile Organic Compounds. Volatile organic compounds (VOCs) are organic chemical compounds that can evaporate under normal indoor temperature and pressure conditions. These compounds are hard to measure due to their volatility. Regulatory bodies outline analysis of volatile organic compounds or pollutants in matrices such as water and air.
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
