Gas Adsorption BET Surface Area Analyzer for Powders

Volumetric nitrogen adsorption instrument measuring specific surface area and pore volume of powders. Used by catalyst, battery, pigment and carbon material producers. It also reports pore volume, helping qualify catalysts, carbons and fine ceramics.

Specification

The sample is degassed under vacuum, then nitrogen adsorption is measured at liquid nitrogen temperature. Single-point and multi-point BET calculations provide specific surface area in m2/g.

Features

• Two analysis ports with one degas port set
• Pressure transducers at 0.1 and 1000 torr
• Single and multipoint BET
• Pore size by BJH method
• Automated dosing manifold
