The stock standard is prepared in PPG or other low vapor pressure solvent. The working standard is prepared by spiking a volume of the stock standard into reagent water. 7.5.2 Stock standard The stock standard should be prepared such that a 1- to 2-µL volume of the working standard (Sec. 7.5.3) added to 10 mL of reagent water and 5 g of

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 ].
