Reliable Hydrogen Peroxide Vapor (HPV) Analyzer System Photometer
THE SMART CHOICE FOR RELIABLE HPV MEASUREMENT
Our Hydrogen Peroxide Vapor (HPV) Analyzer System is a simple turnkey solution for the measurement of hydrogen peroxide and water (H2O2and 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 H2O2and H2O concentrations during cycle development and throughout the actual sterilization cycle. The user gains continuous, accurate data for documentation and validation.
Unlike chemical sensors, the HPV analyzer is able to measure H2O2and H2O concentrations in vapor phase under ambient or vacuum conditions. Many processes use low pressure in the sterilization process to ensure penetration of product packaging. The HPV analyzer allows you to monitor these cycles so you can determine that the correct concentration of H2O2and H2O were present during each cycle.

PROVEN TECHNOLOGY
The HPV Analyzer system utilizes our Guided Wave multi wavelengthClearView db filter photometeranalyzer platform. Optimal wavelengths for H2O2and H2O were selected to produce a simple yet rugged and reliable analyzer for this dedicated application. This new design uses fixed wavelength filter technology, yet still incorporates dual beam design for stability and accuracy. Fiber optic cables take the NIR light energy to the probe in the isolator and returns the non-absorbed light energy back to the analyzer – the optical equivalent of vapor sampling. The HPV analyzer measures as low as 0.1 mg/L of H2O2and 1.0 mg/L of H2O. With the addition of a temperature value, relative humidity and relative saturation measurements can be made.
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.
QUICK INSTALLATION START-UP
The complete system consists of an HPV analyzer, one or two G-SST Vapor Probes, and a pair of fiber optic cables for each probe. The G-SST Vapor Probe mounts in the sterilizer chamber side wall, vapor transfer/recycle lines or optionally on the chamber inner roof with a fiber feed through sanitary cap. HPV analyzer is 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 H2O2and H2O concentration measurements may begin.
PERFORMANCE VALIDATION
When sterilization cycle performance validation is required theG-SST Vapor Probehas 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 H2O2and H2O. It was chosen because of its insensitivity to moisture and temperature conditions. To make a validation measurement, the validation filter is manually positioned into the light path and optical characteristics of the system are checked.
HPV ANALYZER OPTIONAL ENCLOSURES
Typically for medical, pharmaceutical and food industries, the HPV analyzer may be housed in a stainless-steel enclosure. Other enclosure options are available, such as, painted carbon steel, explosion-proof or purged depending on area classification requirements.
