Overview.

The Hiden HPR-20 OEMS is configured for continuous analysis of evolved gases and vapors in electrochemistry as a function of the applied potential on the real-time scale. The ultra-low flow real time sampling capillary allows connection for head space sampling and/or connection to electrochemical cells, EL-Cell for example.

The standard system with 200 amu mass range has a detection capability to less than 100 parts-per-billion. The optional 3F series 300 amu system with triple-stage mass filter offers extended detection levels to 5 parts-per-billion together with enhanced contamination resistance, and is recommended for applications requiring optimum abundance sensitivity and/or analyzes of corrosive or condensable species.
