HPR-20 OEMS

The Hiden HPR-20 OEMS mass spectrometry system is configured for continuous analysis of evolved gases and vapors to measure the volume, pressure, and composition of gas evolved during electrochemical processes (especially the charging, discharging, and aging of lithium batteries) as a function of potential on the real-time scale. The ultralow flow real time sampling capillary allows for connection for head space sampling and/or connection to electrochemical cells, El-Cell for example.

The Hiden QIC-ulf quartz-lined ultra low flow sampling interface operating at up to 200°C provides fast response times of less than < 3 seconds for most common gases and vapours, including water vapour.

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 analyses of corrosive or condensable species.

Feature:

• Quantitative data output in PPM, PPB or % units.
• < 3 seconds response time to changes in gas concentrations.
• Fast scan speeds up to 650 measurements/s for transient analysis.
• APSI-MS soft ionisation mode for suppression of spectral fragmentation providing simplified analysis of complex mixtures.
• New 3D data plot for viewing mass vs. electron energy and intensity.
• New Automated spectral analysis providing peak identification and composition analysis.
• Low dead volume, heated inlet for fast response to vapours.
• Windows® MASsoft Professional PC software for data acquisition, data display and control of quadrupole parameters
