Flow Chemisorption Analyzer: Autosorb 3300
The Autosorb 3300 delivers fully automated catalyst characterization — TPR, TPO, TPD, TPSR, and pulse titration with a four-filament TCD, a safe-touch furnace up to 1,200 °C, and built-in gas blending for up to 36 mixtures from 12 gas inputs.
Manufacturer: Anton Paar — Austria
Overview
The Autosorb 3300 chemisorption analyzer delivers fully automated characterization of catalysts, enabling essential measurements to be performed reliably, quickly, and with exceptional ease of use. Its intuitive, ergonomic interface streamlines operation, while a liquid-cooled furnace ensures safe performance at temperatures up to 1,200 °C. Measurement modes include TPR, TPO, TPD, TPSR, acid and basic site analysis, and pulse titration for active metal area and dispersion. Four integrated titration loops simplify method optimization, and a robust four-filament TCD provides high sensitivity and durability. With 12 gas inputs and two mass flow controllers, the system can generate up to 36 gas mixtures for maximum flexibility.
Essential Chemisorption Done Right: No Guesswork, No Hassle
This chemisorption analyzer redefines simplicity with a workflow that eliminates nearly every manual action. From automatic cell connection and leak checking to fully automated furnace positioning and loop selection, the instrument removes the need for hands-on adjustments. Operators simply place the sample cell assembly into the furnace and press start – nothing more. This radical reduction in touchpoints accelerates training, reduces user to user variability, and keeps your lab moving efficiently without constant operator oversight.
Lowest Operating Costs in Its Class
Designed to deliver confident results in both R&D and QA/QC environments, Autosorb 3300 significantly reduces cost per analysis by eliminating unnecessary consumables and reducing gas usage. Built in gas blending drastically cuts the number of required cylinders and regulators. A regenerable zeolite vapor trap replaces liquid nitrogen cooling for TPR, and the instrument's optimized flow paths ensure lower flow rates and faster gas exchange. With no septa, syringes, ferrules, or O rings to replace – and no compressed air needed for cooling – laboratories benefit from substantially lower recurring costs and fewer workflow interruptions.
The Same Conditions, the Same Results: Precision Every Time
Reliable catalyst characterization depends on uncompromised repeatability. The Autosorb 3300 chemisorption analyzer delivers this automatically, with an integrated, pre calibrated loop system to provide true, temperature and pressure controlled injection volumes unaffected by environmental changes. The Autosorb 3300's high sensitivity current controlled four filament TCD ensures accurate detection across all temperature programmed methods. The instrument resolves small titration peaks and measures active areas down to 0.03 m² (H₂ on platinum at 313 K) for reliable catalyst characterization at very low metal loadings.
Thermal Power that Outpaces Every Legacy System
Autosorb 3300's advanced thermal performance ensures both improved workflow and superior analytical clarity. It delivers rapid temperature ramps, reaching 800 °C at up to 100 °C/min, and even 1,200 °C at up to 25 °C/min. Fast cooldown to 50 °C in as little as 30 minutes further accelerates throughput without sacrificing safety. The chemisorption analyzer's compact furnace design provides highly responsive temperature control, enabling linear temperature ramps, precise hold segments, and stable baselines critical for TPR, TPO, and TPD analysis.
Engineered for Maximum Safety
The Autosorb 3300 chemisorption analyzer is designed to provide controlled heating and cooling profiles for demanding chemisorption applications. Despite its high operating temperatures, the safe-touch design keeps the external surface within 34 °C of ambient to ensure operator safety during high-temperature experiments.
Powerful Software for Catalyst Characterization
Autosorb 3300 is controlled by the workflow-oriented Kaomi React software to support consistent method execution. The software includes a method and sequence editor, real-time instrument visualization, and guided routines for pulse titration and peak deconvolution. Detailed reports for active metal area, dispersion, and other catalyst parameters are generated quickly and reproducibly.
