Analytical method for the determination of N-nitrosodiethanolamine

Translation of DGUV Information 213-536 (former BGI 505-36 or ZH1/120.36)

CAS Number: 1116-54-7 


Method 02 – Capillary GC – limited suitability: category E3

Sampling with a pump and collection on an impregnated glass fibre filter, capillary gas chromatography after desorption and silylation

This method permits the determination of N-nitrosodiethanolamine 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 an impregnated glass fibre filter. The N-nitrosodiethanolamine collected on the filter is extracted with ethyl formate. The extract is evaporated to dryness, silylated and analysed in a gas chromatograph with a thermal energy analyser (TEA) detector.

Limit of quantification (LOQ)

Absolute: 0.14 ng.

Relative: 0.035 µg/m3 N-nitrosodiethanolamine for 2 m3 air sample, 0.5 mL sample solution and 2 µL injection volume.
