Analytical method for the determination of 1,3-butadiene

Translation of DGUV Information 213-526 (former BGI 505-26 or ZH1/120.26)

CAS Number: 106-99-0


Method 02 – Headspace GC

Sampling with a pump and adsorption on activated carbon, headspace gas chromatography (HSGC)

This analytical method describes the determination of the mean concentration of 1,3‐butadiene in the workplace air averaged over the sampling period after personal or stationary sampling.

Principle

A pump draws a defined volume of air from the breathing zone of the worker through an activated charcoal tube. The adsorbed 1,3‐butadiene is desorbed with a mixture of benzyl alcohol/dimethyl sulphoxide/water (90+5+5 v/v). Analytical determination is performed by means of headspace gas chromatography (HSGC) and mass selective detection (MSD).

Limit of detection (LOD)

Absolute: 0,5 µg 1,3-butadiene per adsorption tube.

Relative: 0.025 mg/m3 1,3-butadiene for for an air sample volume of 20 L.

Method 01 – Headspace GC – withdrawn

Sampling with a pump and adsorption on activated carbon, headspace gas chromatography (HSGC)

Validation does no longer comply with the requirements of DIN EN 482.

This method permits the determination of concentrations of 1,3-butadiene in working areas averaged over the sampling time after personal or stationary sampling.

Principle

With a pump carried by a person or used in a stationary position, a measured air volume is drawn through a glass tube filled with activated carbon. The butadiene is then eluted with a non-volatile solvent and determined by headspace gas chromatography according to the internal standard method.

Limit of detection (LOD)

Absolute: 18 µg 1,3-butadiene per activated carbon tube.

Relative: 1.1 mg/m3 ≙ 0.5 mL/m3 (ppm) 1,3-butadiene for a 16-litre air sample.
