High-Pressure Gas Adsorption 0-50/69Mpa

It can automatically conduct high-temperature and high-pressure gas adsorption and desorption isotherm tests, hydrogen storage PCT, hydrogen absorption and desorption, cyclic tests, etc. Designed to withstand pressures up to 69 MPa, the analyzer's robust pipeline and components are specifically engineered for demanding applications such as hydrogen storage, unconventional oil and gas recovery, and other high-pressure gas studies. This ensures reliable, precise results in a wide range of industrial and research settings.

Full Automation

The analyzer offers complete automation from sample pre-treatment to adsorption testing, utilizing an in-situ degassing system and a reliable platform switching mechanism. This streamlined design eliminates the need for manual intervention during lengthy activation and testing processes, allowing testers to focus on analysis rather than operation. The system also supports cyclic adsorption and desorption tests, enabling the evaluation of material durability while significantly reducing repetitive tasks and saving valuable time for users.

High Safety Design

Designed with safety as a top priority, the analyzer incorporates all-pneumatic valves, eliminating the need for solenoid valves, and ensuring enhanced reliability and performance at high safety standards. The instrument is equipped with two high-sensitivity combustible gas detection alarms—one inside and one outside—offering detection limits better than 3% LEL, providing real-time monitoring for hazardous conditions. Additionally, the analysis position is safeguarded by a protective cover, which prevents exposure to high temperatures, ensuring operator safety. This cover also minimizes the impact of external airflow fluctuations, significantly improving test accuracy and the overall stability of the instrument.

Other Feature

The analyzer is equipped with dual flammable gas detection alarms—one inside and one outside the system—for enhanced safety and real-time hazard monitoring. Additionally, the analysis position features a protective cover to shield operators from high temperatures, ensuring full protection during testing.

The instrument incorporates a patented BEST manifold design, providing exceptional integrity and minimizing dead volume to improve measurement accuracy. The all-stainless-steel gas pipeline system utilizes VCR metal hard connectors for superior sealing, and leak detection is conducted with an Inficon helium mass spectrometer, ensuring a high level of system airtightness and reliability.

Equipped with an imported high-precision pressure sensor, the system offers an impressive accuracy of 0.01% FS and long-term stability of 0.025% FS, ensuring precise pressure measurements over extended periods of use.

A non-barrier pollution prevention device, combined with an anti-pumping software program, eliminates the risk of volatile sample boiling under high vacuum conditions. This design prevents contamination of the valve and pipeline system, preserving the integrity and airtightness of the entire system.

The standard sample tube filling rod is equipped with a filter to reduce the free space volume in the sample tube. This effectively prevents sample splashing or contamination of the instrument's internal components, safeguarding both the instrument and the integrity of the test.
