Adsorption instrument TP5085 is a new type of dynamic adsorption analyzer which can be performed at low temperature especially at negative temperature. Many characterizations can be carried out including temperature programmed reduction (TPR), temperature programmed oxidation (TPO), temperature programmed desorption (TPD), hydrogen-oxygen titration (HOT), temperature programmed sulfidation (TPS), temperature programmed surface reaction (TPSR). That is to say it is one important tool for measuring metal dispersion, chemical surface area and particle sizes especially on metal catalysts. Besides, catalytic reaction can be performed on this instrument such as selective oxidation of carbon monoxide at relative low temperature. In addition, the instrument can be optionally connected with mass analyzer and spectrometer for in situ research or/and with a pump for high vacuum.

Both Suitable for bulk and particle samples,

Fully automated operation: only clicking the mouse is needed after sample packing,

More friendly operation system, easier written program and promoted safety protection system,

Mixing gas on line, or using cylinder gas,

Adsorption at 0 ^oC, with carrier gas automatic switch,

Temperature range: -150 ^oC~1100 ^oC,

Using vacuum system for vacuum of 5*10^-5 mbar,

Chromatograph and mass results are also gained simultaneously for one time,

The time needed for stable state: 20 min and for cooling down from 1000 ^oC to r.t.: 15 min,

Applied for: TPD/TPR/TPO/HOT/TPSR/dispersion/chemical surface area,

About 1/3 of the exhausted gas and electric in contrast to other similar instruments.
