Method 2007

Aminoethanol compounds I by GC/FID


This method is for the collection and analysis of aminoethanol compounds from workplace air samples. Samples are collected on silica gel tubes, desorbed in 2 mL 4:1 (v/v) methanol:water, allowed to stand 2 hours with occasional shaking, and analyzed by GC/FID (flame ionization detector).

The working range of the method is 5 to 300 mg/m³ for each compound in a 20 L air sample. Water vapor does not significantly affect the collection efficiency. The sensitivity of the method may be improved at least ten-fold by using a photoionization or nitrogen-selective detector. Note: This method revises P&CAM 270, S140, and Method 2007 (dated 5/15/85).
