Main features:

The latest Chembet PULSAR TPR/TPD (p/n 02139-1) launched by Kantar Instruments represents the best level of fully automated flow analysis and characterization of catalysts. The new Pulsar building is built on top of the world-renowned ChemBET and combines the fully automatic functions of Autosorb-1C/TCD:
- The latest TPRWin PC operation and application software fully automated programmed control analysis sequence
Fully automatic quantitative ring injector and automatic intake valve for pulse titration analysis of metal area and dispersion determination
The temperature climb of the high-temperature furnace can be used for both programmed heating experiments and sample preparation. Both methods can rapidly cool the high-temperature furnace by forcing high-speed air flow.
- Retaining ChemBET's proven TCD detector, it has strong antioxidant and ammonia corrosion resistance capabilities, and stable current control ensures baseline stability and reproducibility of signals
Stainless steel pipelines with maximum chemical compatibility are suitable for a wide range of gases.
The standard high-temperature quartz sample cell can be equipped with a thermocouple to provide accurate temperature measurement of the sample.
- Built in data acquisition card and temperature controller
