Low Pressure Gas Adsorption Isotherm System

Manufacturer: Vinci Technologies
Model Number: LP-GADIS

The LP-GADIS instrument is designed to measure the gas adsorption isotherm of an adsorbent sample. It determines the maximum volume that a sample can store under equilibrium conditions at a given pressure and temperature. The instrument uses the volumetric method which measures pressure and volume of a reference and test cell that are held at a constant temperature and that contain the granulized sample. The apparatus is composed of two sample cells, one reference cell, three pressure transducers and a thermostatic bath. An Excel spreadsheet is provided to enter the pressure and temperature readings and generate the adsorption isotherm report.
