This method is used for the collection and analysis of ethyl acetate. The sample is collected on a coconut shell charcoal tube. After collection, the sample is desorbed with 1mL of carbon disulfide and analyzed by GC/FID (flame ionization detector).
The working range of the method is 0.07 to 790 ppm (0.25 to 2800 mg/m 3) for a 6L air sample
NOTE: This method revises Method S49.
