Analytical method for the determination of 2-butanone oxime

Translation of DGUV Information 213-570 (former BGI 505-70 or ZH1/120.70)

CAS Number: 96-29-7

Synonyms: 

  • Ethyl methyl ketoxime
  • MEKO

Method 01 – GC – limited suitability: category E2

Sampling with a pump and adsorption on Chromosorb 106, gas chromatography after desorption.

This measuring method permits the determination of 2-butanone oxime concentrations in working areas averaged over the sampling time after personal or stationary sampling.

Principle

A pump is used to draw a measured volume of air through a Chromosorb 106 tube. The adsorbed 2-butanone oxime is desorbed with methanol and determined by gas chromatography.

Limit of quantification (LOQ)

Absolute: 0.8 ng 2-butanone oxime.

Relative: 0.2 mg/m3 ≙ 0.05 mL/m3 (ppm) 2-butanone oxime for a 40 litre air sample, 10 mL desorption solution and 1 µL an injection volume.
