Analytical method for the determination of 2,6-dinitrotoluene
Translation of DGUV Information 213-540 (former BGI 505-40 or ZH1/120.40)
CAS Number: 606-20-2
Method 01 – GC – limited suitability: category E2
Sampling with a pump and adsorption on silica gel. Gas chromatography after desorption.
This method permits the determination of 2,6-dinitrotoluene 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 a glass tube filled with silica gel. The adsorbed 2,6-dinitrotoluene is then desorbed with methanol and determined by gas chromatography.
Limit of quantification (LOQ)
Absolute: 0.1 ng 2,6-dinitrotoluene.
Relative: 0.005 mg/m³ ≙ 0.0007 ml/m³ (ppm) 2,6-dinitrotoluene for a 20-litr air sample.
