Analytical method for the determination of 2-naphthylamine
Translation of DGUV Information 213-509 (former BGI 505-09 or ZH1/120.9)
CAS Number: 91-59-8
Method 02 – GC after desorption – withdrawn
Sampling with a pump and adsorption on impregnated silica gel. Gas chromatography after desorption.
For the assessment of working areas, both personal and stationary sampling are possible.
Principle
With a pump a measured air volume is drawn through a glass tube filled with impregnated silica gel. The adsorbed 2‐naphthylamine is desorbed with a mixture of dichloromethane and 2‐aminoethanol and determined by gas chromatography.
Limit of quantification (LOQ)
Absolute: 2 ng 2‐naphthylamine.
Relative: 0.05 mg/m3 ≙ 0.009 ml/m3 (ppm) 2‐naphthylamine for a 40‐litre air sample.
