Abstract
The present application is directed to a process for calibrating a detection apparatus, especially an ion mobility spectrometer, using isoflurane (CAS Reg. No. 26675-46-7) as a chemical standard whereby calibrating the detection apparatus for a known target chemical is based on an evaluation of the experimental data collected for the negative isoflurane monomer ion against the experimental data collected for the negative isoflurane dimer ion.
