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 ].
Vials should be treated as directed to be free of organic chemical contamination. 2. If samples contain residual chlorine and measurements of the concentrations of disinfection by-products (trihalomethanes etc.) are to be made, add approx. 25 mg of ascorbic acid to the bottle before filling.
