Abstract The monitoring of vapour phase hydrogen peroxide (VHP) has gained increasing importance in the pharmaceutical industry because sterilization using VHP has proven to be a good alternative to previously used sterilizing methods. The current method based on bubbling air through an acid solution with subsequent laboratory analysis, is not practical for monitoring personal exposures. A commercially-available electrochemical sensor direct-reading instrument designed for personal monitoring of VHP was evaluated in the laboratory and under typical workplace. Time-weighted average concentration data from the direct-reading instrument was compared with concentration data from the existing analytical method. Selected performance characteristics of the instrument also were investigated, including reproducibility, response and recovery times, calibration frequency and suitability of the calibration adapter. Results suggest that the instrument provides a means for simple and accurate monitoring of personal exposures to VHP in workplace environments.
