Method 28

Acrylic Acid by HPLC/UV

This method is for the determination acrylic acid from workplace air. Samples are collected on two Anasorb 708 sampling tubes connected in series. After collection the samples are desorbed with methanol/water (1:1) and analyzed by high performance liquid chromatography (HPLC) using an ultraviolet (UV) detector.
