Tekniska fördelar

◆ High-throughput and high-efficiency

Stöder analys av upp till 12 prover samtidigt.

◆ Truly fully automated

International first: automatic switching between degassing furnace and Dewar cup, no manual transfer of sample tubes or degassing furnace required;

◆ High time utilization

Solves the time waste issue of conventional instruments where degassing is completed after work hours, but testing cannot start. Enables sample loading after work and data viewing the next day;

◆ Complete elimination of "helium contamination"

Pioneering solution in the international arena: helium gas dead volume test → vacuum heating degassing → adsorption test, improving test accuracy by addressing the helium contamination challenge in micropore analysis;

◆ Anti-dust degassing

Supports "pressure-controlled heating" + "pressure-controlled vacuuming", automatically adjusting temperature programming and vacuuming rate based on pressure changes to prevent sample dusting;

◆ Supports automatic cycle testing

Automatic degassing + testing cycle for evaluating material adsorption performance stability and adsorption lifespan;

◆ "Pressure-controlled heating" sample pore protection technology (compliant with international standard ISO 9277:2022)

A temperature programming technique under gas pressure control, automatically starting and stopping temperature programming based on pressure changes to prevent excessive gas release and damage to sample pores (a common issue with micropore samples. Once pore damage occurs, it is difficult to detect and is a major source of instability in micropore sample test results).

◆ "Automatic constant temperature zone" patented technology
The curve shows that the 24-hour change rates of the "adsorption chamber equivalent volume" under three constant temperature zone methods are: BSD temperature zone servo automatic constant: 0.10%, isothermal clamp: 0.25%, liquid level sensor: 0.55%

◆ Convenient installation and sealing
Single analysis station with one-time sealing technology for 6 sample tubes, no need to seal each tube individually, providing unparalleled efficiency;
◆ Fully constant temperature gas path system
The internal gas path system of the instrument is fully constant temperature up to 40°C, with accuracy better than ±0.01°C;
◆ Upward-opening door
Humanized and easy to open and close, saving laboratory space;
◆ Electric turbo liquid nitrogen pump
Humanized liquid nitrogen addition, stepless speed regulation, free movement, safe and convenient, no liquid nitrogen contamination;
◆ Öppna datagränssnitt
The software can be integrated with LIMS to upload test results to LIMS.
