Analytical method for the determination of epichlorohydrine

Translation of DGUV Information 213-508 (former BGI 505-08 or ZH1/120.8)

CAS Number: 106-89-8

Synonym: 1-Chloro-2,3-epoxypropane


Method 02 – GC

Sampling with a pump, adsorption through an adsorption tube, gas chromatography after thermal desorption.

For the assessment of working areas, both personal and stationary sampling are possible.

Principle

Sampling is performed by drawing a defined volume of air through an adsorption tube filled with Tenax TA. After thermal desorption, analysis is carried out by gas chromatography with a flame ionisation detector (FID).

Limit of quantification (LOQ)

Absolute:  0.047 µg.

Relative:  0.039 mg/m³ for an air sample volume of 1.2 L.
