Simple turnkey solution for the measurement of hydrogen peroxide and water (H₂O₂ and H₂O) concentrations in vapor phase

Our GUIDED WAVE™ HPV™ Hydrogen Peroxide Vapor Analyzer System is a simple turnkey solution for the measurement of hydrogen peroxide and water (H₂O₂ and H₂O) concentrations in vapor phase. These are both measured together because they are codependent. The analyzer operates in real time, which takes the guesswork out of determining the H₂O₂ and H₂O concentrations during cycle development and throughout the actual sterilization cycle. The user gains continuous, accurate data for documentation and validation.

Easy Operation and Control

The HPV analyzer is controlled via its touch screen or remotely via Ethernet (Modbus TCP/IP). All of the analytical calculations are encoded in the software.   The complete system consists of an HPV analyzer, one or two G-SST probes, and a pair of fiber optic cables for each probe. The HPV analyzer is pre-calibrated at the factory. No programming is required by the user. Start-up requires powering the HPV analyzer, connecting the probe or probes via the fiber optic cables, taking a ZERO reading in the dehumidified isolator and the H₂O₂ and H₂O concentration measurements may begin.

Performance Validation

When performance validation is required the G-SST probe has a built-in validation filter (optional) made of polymeric material. This makes validation of performance easy, at any time. The filter has unique spectral characteristics at the wavelengths used to measure H₂O₂ and H₂O. It was chosen because of its insensitivity to moisture and temperature conditions. To make a validation measurement, the validation filter is temporarily moved into the light path and the optical characteristics of the system are checked.
