Method 2538

Acetaldehyde by GC/FID

This method is used for the determination of acetaldehyde.  The sample is collected on a 2-(hydroxymethyl)piperidine (2-HMP) coated XAD-2 sorbent tube, desorbed in toluene, and analyzed by GC/FID (flame ionization detector).  

The working range of the method is 0.74 to 407 ppm (1.3 to 730 mg/m³) for a 3 L air sample.

NOTE: This method is an adaptation of OSHA Method 68 and is a convenient alternative to NIOSH Method 3507.
