Preconditioning

Degassing system and analyzing system run completely independently without interfering with each other, and the degassing station has an independent timing function, which can support sample degassing at different temperatures and different times synchronized with the test;

With "ordinary heating and vacuum molecular diffusion mode" and "molecular replacement mode" two optional functions.

Anti-pumping

The original vortex dust reduction principle of the hardware anti-pollution device, combined with the software anti-pumping program completely eliminates the volatile samples in the high vacuum when the phenomenon of boiling Yang dialysis, thus avoiding the volatiles contaminate the valve pipeline.

Anti-pollution

The original vortex dust reduction principle of non-blocking anti-pollution device, combined with the software anti-siphoning program to completely eliminate the volatile samples in the high vacuum when the phenomenon of boiling Yang dialysis, so as to avoid contamination of the valves and pipelines caused by the decline in the system tightness of the situation.

Dead volume test

With He gas dead volume test function; with density extrapolation method, for the known true density of the specimen, the dead volume to obtain more accurate, more efficient testing.

Warm zone test

With program control He cold and hot zone temperature zone test function.

True density test

With He true density test function, high test accuracy, good repeatability

High pressure gas path system

All stainless steel gas line system, the manifold is BEST manifold, the remaining small amount of piping is imported 316L stainless steel piping. The high integration and anti-interference ability of the manifold system can effectively reduce the dead volume space and effectively improve the stability and service life of the instrument.

20MPa high pressure gas line system connectors with VCR hard connection, 316L stainless steel tubing, system pressure tested to 35MPa. All-metal VCR hard connection can realize safe, reliable, easy to install or dismantle the pipeline quick connection.

69 MPa ultra-high-pressure gas line system fittings are hard-wired with ferrule fittings, 316L stainless steel tubing, and the system is pressure tested to 100 MPa.

The vacuum leakage rate is <5*10-5 Pa-L/S by Infocon Helium Leak Detector before the instrument is shipped out from the factory, so that the gas tightness of the instrument is fully guaranteed.

Control system

The valve adopts high security, high pressure resistant all imported 316 stainless steel high pressure pneumatic valve, which can realize the automatic on-off control within the pressure range of 20MPa or 69MPa, and the service life is up to 500 million times.

Vacuum system

Instrument degassing system and analyzing system are independent of each other, avoiding the problem of mutual contamination caused by sharing a set of gas circuit system. Bipolar direct-connected vacuum pump, the vacuum degree reaches 10-2Pa;

Molecular pump system can be optional, the ultimate vacuum reaches 10-8Pa; the whole process software automatically controls the start and stop of the pump.

Safety measure

High safety, the use of pneumatic valves, no solenoid valve, high-performance explosion-proof level; the instrument inside and outside the two high-sensitivity combustible gas detection alarms, detection limit better than 3% LEL. analysis position with a protective cover, completely eliminated due to the high temperature of the experimental operators caused by the injury; more importantly, effectively eliminate the external airflow changes on the test, greatly improving the instrument's testing accuracy and stability. More importantly, it effectively eliminates the influence of external airflow changes on the test, greatly improving the instrument's testing accuracy and stability.
