Fully automated analysis sequences are programmed using the new TPRWin PC software. Titrations for metal area and dispersion determination use a new automatic loop injector and automatic gas switching. Furnace temperature ramping provides for temperature programmed methods (TPR, TPD, TPO, TPSR-known collectively as TPX) and sample preparation, both including rapid furnace cooling using forced air for higher throughput.
New multiple TPX measurements can be automated into a single squences. The PULSAR retains the ChemBET's proven TCD detector - both oxidation AND ammonia resistant, with stable current control for baseline stability and reproducible signals. Plumbed in stainless-steel for maximum chemical compatibility, the PULSAR is ideal for use with a wide-range of gases. High-temperature quartz sample cells are standard, as is the in-cell thermocouple providing accurate sample temperature measurements.
Options include a Quadrupole Mass Spectrometer, and an external digital gas blender/mass flow controller, and a subambient TPX option.
The resulting data are used to:
Confirm or predict catalyst activity
Determine optimal catalyst preparation conditions for industrial use
Measure efficiency of regeneration of
used catalysts
Quickly screen experimental catalysts
Calculate activation energies for a given reaction
Determine relative acid strengths
