Micromeritics AutoChem III

AutoChem III – Advanced Catalyst Characterization and Temperature-Programmed Analysis

The Micromeritics AutoChem III is the world’s most advanced and widely cited system for catalyst reactivity and chemisorption analysis. It delivers exceptional automation, accuracy, and safety for temperature-programmed reactions including TPR, TPO, TPD, TPSR, and pulse chemisorption, as well as BET surface area and metal dispersion measurements.

Designed to save hours of operator time each day, AutoChem III features a dynamic clamshell furnace with rapid AutoCool cooling, eliminating the need for cryogenic liquids. Its patented gas blending and multi-zone temperature control ensure unparalleled precision and stability, while the high-sensitivity TCD detector doubles measurement resolution for smaller samples and complex reactions.

At Prisma Scientific, our specialists provide training, method development, and expert support to help laboratories extract maximum insight from AutoChem III’s advanced chemisorption and temperature-programmed capabilities.
