Occupational pharmaceutical exposure assessment by ion mobility spectrometry (CAT#: STEM-ST-0108-LJX)

Introduction

The qualitative and quantitative capabilities of ion mobility spectrometry (IMS) as a comprehensive and powerful tool in workplace air monitoring have been demonstrated on the example of a Spanish pharmaceutical company. The developed IMS based procedure is capable of detecting and determining in air samples the active pharmaceutical ingredients (APIs) manipulated and/or produced in this pharmaceutical industry. Sensitivity, in the ng-pg range, selectivity, possibly to provide results in near real time, and reduction of analysis costs are the most important properties that ratify IMS as a serious alternative in occupational exposure assessment. The possibility of false positives by drift time interferences and false negatives by competitive ionization and also desorption process interferences has been deeply evaluated.
