The Autosorb 3300 chemisorption analyzer automates catalyst characterization, enabling critical measurements to be completed efficiently, consistently, and with minimal operator effort. A user-friendly ergonomic interface enhances usability, while the liquid-cooled furnace supports safe operation at temperatures reaching 1200 °C.
The system supports a range of measurement techniques, including TPR, TPO, TPD, TPSR, acid and basic site analysis, and pulse titration for evaluating active metal area and dispersion.
Method development is simplified through four built-in titration loops, while a robust four-filament TCD ensures dependable, high-sensitivity detection. Equipped with 12 gas inlets and two mass flow controllers, the analyzer can generate as many as 36 gas mixtures to accommodate diverse application requirements.

Key Features
Essential Chemisorption Done Right: No Guesswork, No Hassle
This chemisorption analyzer streamlines operation through a workflow that minimizes nearly all manual intervention. Automatic cell connection, leak verification, furnace positioning, and loop selection eliminate the need for routine hands-on adjustments.
To begin an analysis, operators simply place the sample cell assembly in the furnace and start the run. By reducing user interaction, the system shortens training time, improves consistency between operators, and supports efficient laboratory operation without constant supervision.

Lowest Operating Costs in Its Class
Engineered for dependable performance in both R&D and QA/QC settings, the Autosorb 3300 helps reduce the cost of analysis by minimizing consumable requirements and lowering gas usage. Built-in gas blending decreases the number of cylinders and regulators needed for operation.
A regenerable zeolite vapor trap eliminates the need for liquid nitrogen cooling during TPR, while optimized flow pathways support reduced gas flow rates and more efficient gas exchange. Users do not need to replace septa, syringes, ferrules, or O-rings, and compressed air is not required for cooling, meaning laboratories can achieve lower ongoing operating costs and experience fewer interruptions to routine workflows.

The Same Conditions Lead to the Same Results: Precision Every Time
Accurate catalyst characterization requires consistent, highly repeatable measurements. The Autosorb 3300 chemisorption analyzer delivers this automatically through an integrated, pre-calibrated loop system that provides true injection volumes controlled for temperature and pressure, regardless of environmental variations.
For all temperature-programmed methods, the Autosorb 3300 uses a high-sensitivity, current-controlled four-filament TCD to ensure precise detection. The system can resolve small titration peaks and quantify active areas as low as 0.03 m2 (H2 on platinum at 313 K), supporting dependable catalyst characterization even at very low metal loadings.

Thermal Power That Outpaces Every Legacy System
Enhanced thermal performance in the Autosorb 3300 supports higher productivity and improved analytical clarity. The system achieves rapid temperature ramping, reaching 800 °C at rates of up to 100 °C/minute and 1200 °C at rates of up to 25 °C/minute. Cooling to 50 °C can be completed in as little as 30 minutes, increasing sample throughput while maintaining safe operation.
The compact furnace design enables highly responsive temperature control, which is essential for TPR, TPO, and TPD measurements. This capability supports linear temperature ramps, precise hold periods, and stable baselines throughout the analysis.

Engineered for Maximum Safety
For challenging chemisorption applications, the Autosorb 3300 chemisorption analyzer delivers controlled heating and cooling profiles. Even during high-temperature operation, the safe-touch design maintains the exterior surface within 34 °C of ambient temperature, helping protect operators during testing.
