Chemisorption Analyzers

METAL AREA, DISPERSION, TPR/TPO/TPD

Autosorb^™-1C/TCD

Total catalyst characterization system. Uniquely combines manometric and flow techniques. Measurement capabilities include active site characterization by reactive gas chemisorption and desorption. Isothermal techniques yield both strong and weak chemisorption for metal area and related quantities, plus heats of adsorption. Fully automated temperature-ramped flow methods produce TPR/TPO and TPD profiles including acid site strength. Textural properties by physisorption such as surface area and micro- and mesopore size distribution are enhanced with state-of-the-art calculation models. more...

Autosorb^™-1C

Manometric (static/volumetric) chemisorption and physisorption capabilities combined in a single instrument. Includes all of the physisorption qualities of the Autosorb-1MP/Kr model as standard. Fully automated in-situ treatment of sample includes gas switching and heating profiles. User-programmable, automatic protocols combine treatment and analysis for hands-off operation. Chemi-isotherms yield metal area, dispersion, nanocluster size and spillover. Detailed calculation and reporting software for comprehensive catalyst characterization. Shown with optional close-coupled mass spectrometer. more...

ChemBET PULSAR^™TPR/TPD

The very best in catalyst characterization using automated flow methods of analysis. 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 and sample preparation, both including rapid furnace cooling using forced air for higher throughput. more...

ChemBET^™ TPR/TPD

Compact catalyst characterization unit for metal area, dispersion, nanocluster size and surface area measurements (BET) by rapid, flow (pulse injection) techniques. Programmed linear rates for quality TPR/TPO/TPD profiles; includes data recording, calculation and reporting software. Built-in, changeable calibration loops. Includes interface port for optional mass-spectrometer. more...

Autosorb^™-1C/MS

Close-coupled mass spectrometer (MS) adds gas identification (speciation) for in depth reaction studies. Unique vacuum chamber and built-in sample introduction system brings substantial cost savings over separate systems. Automatic integration of temperature and mass signals gives multiple TP curves. Can be combined with TCD option (as shown, and above) and/or Vapor option. more...
