Environment
In this Application Note, the 21 volatile compounds were measured using the Purge & Trap method. Among the target compounds, chloroethane, vinyl chloride, chloromethane, and 1,3-butadiene exist as gases at room temperature. They were dissolved into chilled methanol to prepare the standard samples. The peaks of chloromethane, vinyl chloride, bromomethane and 1,3-butadiene are overlapped with the peaks of methanol or water, causing baseline fluctuations. Thus special care is needed when deciding the analytical conditions.
