Capable of automated operation with up to 24 samples, requiring no personnel oversight.
Utilizes high-precision pressure regulators for stable and accurate gas flow control.
Features gas lines constructed entirely from passivated and polished 316 stainless steel, with sealing rings made of PTFE material for high-temperature resistance and zero volatile emissions.
Employs heating gas lines made of imported high-inertia deactivation stainless steel, with PTFE material seals for high-temperature resistance and zero emissions.
Incorporates precision high-temperature-resistant injection valves in the heating valve box, featuring no dead volume. The injection valve operates with motor drive, eliminating the need for external gas drive and ensuring convenient use. The maximum operating temperature reaches 240°C.
Adopts an integrated design for the heating valve box and heating gas path, reducing intermediate links and minimizing the issue of low resolution caused by dead volumes.
Optimizes dead volume reduction by calculating the optimal diameter of the connection point between the analysis tube and the gas path, through meticulous consideration of the analysis tube and gas path diameters.
Equipped with standard sample simulation sampling functionality.
Demonstrates strong compatibility with various domestic and international brands of gas chromatographs. Simple installation without the need for any parameter or setting adjustments on the gas chromatograph, ensuring consistency and integrity of gas chromatography results.
