Maintenance mode allows for easy instrument maintenance, fault diagnosis, and leak detection.
Features 40 sample positions, with dual-channel simultaneous sampling for doubled efficiency. Equipped with a convenient 7-inch capacitive touchscreen for easy operation.
Utilizes semiconductor cooling technology to save on operating costs.
Capable of lowering trap temperatures to as low as -35°C (depending on ambient temperature).
Fully automates processes such as enrichment and sampling.
Employs gas lines made entirely of passivated and polished 316 stainless steel, with sealing rings made of PTFE material for high-temperature resistance and zero volatile emissions. Sample gas path utilizes passivated RESTEK tubing, Siltek®/Sulfinert® treated stainless steel tubing combined with stainless steel ferrules and fully heated throughout.
Utilizes stainless steel variable-diameter sampling needles with side openings, ensuring strength while significantly increasing the number of sampling pad uses.
Incorporates built-in standard sample simulation sampling functionality.
Demonstrates strong compatibility with various GC and GC-MS systems.
Capable of synchronizing startup with chromatographs and workstations, and can read chromatograph ready signals for seamless coordination with chromatography processes.
