Autosorb-3B
Automatic Surface Area and Pore Size Analyzer

The Autosorb-3B, is a highly efficient, cost effective, 3-sample system designed for laboratories with higher test volumes needing multiple sample capability.

This means multiple sample preparation as well as simultaneous analysis of samples.
This means the flexibility to do multiple methods of analyses at the same time (single point or multipoint B.E.T. or full isotherm).
It also means uncompromised quality in technical performance and analytical results.

Degasser Side

The degasser side of the Autosorb-3B features three sample preparation stations. Its independent vacuum system adds important flexibility by permitting sample preparation concurrently with sample analysis. Each preparation station provides an independent heating control with temperature readout. A vacuum thermocouple gauge is provided to determine when each sample is completely degassed. A built-in, long-life cold trap keeps the vacuum system clean and free of degas by-products. This also prevents sample contamination due to back-streaming of pump oil vapors.

Analyzer Side

     The analyzer side of the Autosorb-3B provides three sample measurement stations. Each station operates automatically, independently and simultaneously.
     Quantachrome's proprietary BatchStart feature provides parallel processing for fast initialization of analyses. Analysis times are further reduced by the MaxiDose feature that automatically and intelligently adjusts the amount of gas introduced in accordance with sample characteristics.
     Standard software provides automatic data acquisition, real-time status display and comprehensive graphical and tabular reporting capabilities using Windows® software.
     Data reduction includes multipoint B.E.T. surface area, Langmuir surface area, Dubinin-Radushkevich surface area, total pore volume, B.J.H. pore size distribution plus t-plots and the MP technique for micropore analysis.
     Options for low pressure data acquisition expand the instruments capabilities to include measurements of low surface area materials using krypton gas or for detailed micropore distribution studies by a wide range of modern techniques such as Density Functional Theory and the Korvath-Kawazoe method.
