The iSorb HP gas-sorption analyzers are ideal for assessing materials used in gas storage, gas separation, or emission control applications.
Featuring high-accuracy transducers, accurate manifold temperature regulation, and an integrated library of advanced equations of state, the iSorb HP line provides access to reliable gas adsorption and kinetic data up to 100 bar or 200 bar absolute.
Optional temperature-control accessories enable measurements over a temperature range of 75 K to 773 K.

Key Features
Robust Manifold Design Ensures Results are Not Affected by Temperature and Ambient Conditions
High-pressure testing requires a controlled temperature to achieve accurate, precise results. As such, the iSorb HP manifold is thermostatically warmed above ambient temperature to improve stability and shield from environmental variations.
Microprocessor-driven digital pressure transducers deliver temperature-compensated pressure measurements. The software monitors the stability of the manifold temperature and gas pressure before dosing into the sample cell; readings taken at steady temperatures yield the most accurate and precise measurements possible. Metal VCR seals and pneumatic valves guarantee leak-tight operation.

Highly Flexible Experimental Conditions
iSorb HP offers a selection of high pressure sample cells designed to support a broad range of sample forms: powders, granules, films, and monoliths. Sample temperature is regulated using multiple accessories ranging from cryogenic (75 K) to high temperatures (773 K).
The low-volume microcell allows the user to evaluate material performance even when the sample quantity is limited. Reduced void space, combined with precise temperature control, eliminates the need for blank-subtraction runs.
The compact pressure booster delivers a 4:1 compression output, sustaining 200 bar with only 55 bar remaining in the gas cylinder to save money and resources.

Peace of Mind with Built-In Safety
Operating at elevated pressures with hazardous gases makes safety a top priority. With the iSorb HP, sample cell pressure is continuously tracked, even during a power failure; in the event of a power outage, the instrument automatically shuts all valves. Its “Safe State” routine restores the manifold and sample cell to ambient pressure using helium, allowing easy sample removal.
The intelligent software includes an automatic leak-detection algorithm that can distinguish between adsorption and a leak. If a leak is identified, the instrument halts the analysis, returns to a safe state, and can activate an external alarm. An automated supply-line cleaning routine prevents the mixing of incompatible gases.

Insights into Sample Kinetics, Heat Adsorption at Different Temperatures, and More
Surface excess isotherms can be readily generated using the iSorb HP through two integrated approaches: traditional target-pressure mode or quicker pressure dosing.
Users may also examine sample kinetics for every data point acquired and compute the heat of adsorption from several isotherms measured at varying analysis temperatures. Absolute adsorbed amount isotherm and storage capacity calculations support R&D in identifying future innovative materials for gas storage capabilities.

Permanent Control of Instrument Status and Health
The valve management system tracks every valve cycle to assist in planning maintenance schedules. The exportable visual log file captures all pressure and temperature data, valve actions, and animated graphics for quick diagnostics and full analysis playback.
