Compatible with Hydrogen Peroxide Vapor (HPV) Analyzer
For hydrogen peroxide or other vapor applications, our Guided Wave 50 cm G-SST Vapor Probe provides an efficient, simple and easy interface between the vapor chamber, and our Hydrogen Peroxide Vapor (HPV) analyzers. The probe clamps into a standard 2-inch Tri-Clover® sanitary fitting and can be mounted in the vapor chamber, feed line, or return line. Alternatively, a flangeless version of the G-SST Vapor Probe is available for mounting inside the chamber, with a fiber feed through sanitary cap.
Primary Advantages New 50 cm Pathlength G-SST Over the Previous 25 cm, 28.3 cm and the Original 50 cm G-SST Probe
- The double pass beam design (folded path) provides double of the beam interaction with the gases in the sterilizer chamber. This increases the achievable signal-to-noise making for a more accurate and stabile measurement. Since the absorbance of water and Hydrogen Peroxide vapor is very weak, this is a significant improvement in the measurement accuracy.
- The optics are sealed behind a window which isolates the lenses from the sterilization chamber; thus the probe is no longer sensitive to index of refraction changes, This makes the measurements are more stable under widely varying conditions of deep vacuum to high concentrations of water and hydrogen peroxide vapor.
- To allow the probe to be quickly serviced by a technician, the perforated cage around the beam path was to the open structure shown below. With the lenses behind an o-ring sealed window, there is no adhesive degradation increasing the service life of the probe.
