The Secrets to High-Quality Micropore Isotherms | 1: Proper Sample Preparation

In this four-part series, Anton Paar experts reveal how to achieve consistent, accurate results using the Autosorb gas sorption analyzer. Each 10-15-minute session focuses on a critical factor in micropore isotherm quality, offering practical insights for reliable, high-resolution data.


Before a single data point is collected, the quality of your results depends on how well your sample is prepared. This session takes an in-depth look at the techniques, tools, and considerations that define successful sample preparation.

See how flowing gas and vacuum degassing compare in performance, learn best practices for controlled heating to remove contaminants, and discover how to prevent pore structure alteration during pretreatment.

The discussion will also cover the benefits of automated degassing and demonstrate the value of high vacuum systems combined with a cold trap. These features help make preparation easier, faster, and more reliable — ensuring that every isotherm you measure starts from a clean foundation.
