Analytical method for the determination of 1,2-dichloroethane
Translation of DGUV Information 213-548 (former BGI 505-48 or ZH1/120.48)
CAS Number: 107-06-2
Method 01 – Headspace-GC after desorption – limited suitability: category E1
Sampling with a pump and adsorption on activated carbon, headspace gas chromatography after desorption.
This method permits the determination of 1,2-dichloroethane 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 1,2-dichloroethane is eluted with a 3 : 1 dimethylacetamide/water mixture and analysed by headspace gas chromatography (HSGC). Evaluation is performed according to the internal standard method (1,4-dioxane) using a flame ionization detector (FID).
Limit of quantification (LOQ)
Relative: 0.08 mg/m3 of 1,2-dichloroethane for 10 L air sample, corresponding to 0.8 µg 1,2-dichloroethane per activated carbon tube.
Issue
March 1991
The measuring method is of limited suitability (E1).
The complete measuring method is available in the Wiley Online Library: Method for the determination of 1,2-dichloroethane (Analyses of Hazardous Substances in Air, Volume 4, 1999).
