Translation of DGUV Information 213-512 (former BGI 505-12 or ZH1/120.12)

CAS Number: 75-01-4

A valid analytical method for the determination of vinyl chloride is currently only available in German.

Method 02 – Headspace GC – limited suitability: category E1

Sampling with a pump and adsorption on activated carbon, headspace gas chromatography after desorption

This method permits the determination of vinyl chloride concentrations in working areas averaged over the sampling time after personal or stationary sampling.

Principle

With a pump a measured air volume is drawn through activated carbon. The adsorbed vinyl chloride is desorbed with dimethylacetamide /water (3:1) and analysed by headspace gas chromatography (HSGC). Evaluation is carried out according to the internal standard method (diethyl ether) using a flame ionization detector (FID).

Limit of quantification (LOQ)

Absolute: 0.2 µg vinyl chloride per activated carbon tube.

Relative: 0.03 mg/m3 vinyl chloride for 7 L air sample.

The measuring method is of limited suitability (E2).

The complete measuring method is available in the Wiley Online Library: Method for the determination of vinyl chloride (Analyses of Hazarodous Substances in Air, Volume 4, 1999).


Method 01 – GC – withdrawn

Sampling with a pump and adsorption on activated carbon, gas chromatography after desorption

This method permits the determination of the concentration of vinyl chloride in working areas averaged over the sampling time after personal or stationary sampling. With a pump, which is carried by a person or installed in a stationary position, a measured air volume is drawn through a glass tube containing activated carbon. After the adsorbed vinyl chloride has been desorbed with carbon disulfide it is determined by gas chromatography.

Principle

With a pump a measured air volume is drawn through activated carbon. After desorption with carbon disulfide the adsorbed vinyl chloride is determined by gas chromatography.

Limit of detection (LOD)

Absolute: 1 ng vinyl chloride

Relative: 0.2 mL/m3. This corresponds to 0.5 mg/m3 vinyl chloride for a 20 L air sample.
