New measurement procedure for esters

Status:

completed 09/1999

Aims:

Esters play an important role as parts of solvent mixtures in chemical agents. The method utilised within the scope of the BG-measuring system for hazardous substances (BGMG) was developed already in the middle of the eighties. As far as DIN EN 482 "Workplace atmospheres - general requirements for the performance of procedures for the measurement of chemical agents" is concerned it is, however, not completely validated.

Activities/Methods:

The new measurement procedure allows personal and stationary measurements.The sampling medium is activated charcoal. Desorption takes places with a ternary mixture of methylalcohol, methylene chloride and carbon disulfide. Analysis is made by gas chromatography with flame ionization detector (GC/FID). The detection limit comes to 1mg/m³ for a sampling time of two hours.

Results:

The measurement procedure is used as a standard in the scope of the BG-measuring system for hazardous substances - BGMG and it meets the requirements of DIN EN 482.
