VHP Remote Particle Counters

    HYDROGEN PEROXIDE VAPOR IN LIFE SCIENCE APPLICATIONS

    A widely used method to inactivate bio-contamination on surfaces in GMP controlled areas is sporicidal gassing using vaporized hydrogen peroxide (VHP). This decontamination process uses a free radical reaction to kill microorganisms on surfaces. VHP is a powerful oxidizing agent and if drawn into a particle counter it can potentially damage or contaminate the instrument optics. This damage can result in false particle counts, calibration errors or a complete particle counter malfunction. To address this issue, TSI offers a range of VHP-resistant remote particle counters utilizing VHP resistant coatings and materials.
