    Description

    The ChemBET Pulsar TPR/TPD represents the very best in catalyst characterization using automated flow methods of analysis. Fully automated analysis sequences are programmed using the TPRWin software. Titrations for metal area and dispersion determination use an automatic loop injector and automatic gas switching. Furnace temperature ramping provides for temperature programmed methods and sample preparation, both including rapid furnace cooling using forced air for higher throughput. The Pulsar uses 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. An optional quadrapole mass spectrometer is available allowing for species differentiation during temperature programmed analyses.
