High-Pressure Volumetric Gas Sorption Analyzer: iSorb

The iSorb HP gas sorption analyzers are perfect for evaluating materials in gas storage, gas separation, or emission control applications. With high-precision transducers, precise manifold temperature control, and a built-in library of advanced equations of state, the iSorb HP series gives you access to high-quality gas adsorption and kinetic data to a maximum of either 100 bar or 200 bar absolute. Optional temperature control accessories allow measurements over a temperature range of 75 K to 773 K.

One-station gas sorption analyzer
High-pressure measurements up to 100 bar pressure

Features

Robust manifold design ensures results unaffected by temperature and ambient conditions

High-pressure experiments require well-controlled temperature for accurate and precise measurements. Therefore, the manifold of the iSorb HP is thermostatically heated above room temperature for better stability and isolation from environmental changes. Microprocessor-based digital pressure transducers provide temperature-compensated pressure readings. The software monitors the stability of the manifold temperature and gas pressure before dosing into the sample cell; readings taken at stable temperatures provide for the most precise and accurate measurements. Metal VCR seals and pneumatic valves ensure leak-tight operation.

Highly flexible experimental conditions

iSorb HP features a variety of high pressure sample cells that accommodate a wide range of sample types: powders, granules, films, and monoliths. Sample temperature is controlled by several accessories from cryogenic (75 K) to elevated temperatures (773 K). The low-volume micro cell enables you to determine the performance of your materials even when sample amount is limited. The reduced void space and excellent temperature control help eliminate the need to perform blank subtraction runs. The compact pressure booster produces a 4:1 compression result maintaining 200 bar with as little as 55 bar left in the gas cylinder to save you money and resources.
