IMI-FLOW: Gas Sorption measurements by Dynamic sorption and thermal desorption
Features
In addition to all the features of the IMI Manometric systems, IMI-Flow permits measurements and sample treatments using flowing gas.
- Multiple flow controlled gas inputs
- Automatic gas species selection
- Variable composition mixed gas experiments
- Integration of Hiden Analytical Mass spectrometer with synchronised data acquisition
- Extremely high sensitivity available from Mass spectrometric
determination
- Measurement of sorption capacity on milligram sized samples
- Desorption of trace impurities
- Sequential manometry, thermal desorption
