The Secrets to High-Quality Micropore Isotherms | 2: Determining Void Volume

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.

Determining void volume is one of the most critical steps in achieving accurate micropore measurements, but it is also one of the most frequently overlooked. In this session, we’ll explore proven methods for ensuring void volume consistency throughout the entire adsorption–desorption cycle.

You’ll learn how the wicking technique and temperature control systems, like TruZone™, complement one another to reduce variability from thermal gradients and gas expansion, providing dependable baseline accuracy.
