Catalyst Characterization Unit
Product Announcement from Quantachrome Instruments
The PULSAR represents the very best value in catalyst characterization using automated flow methods of analysis, including pulse titration.
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 include rapid furnace cooling using forced air for higher throughput.
Multiple TPX measurements can be automated into a single sequence. The PULSAR employs a 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.
