Offers multiple fault detection and handling modes, automatically halting operations and providing alerts in case of mechanical anomalies, ensuring reliable and damage-free high-precision movement. Maintenance mode enables easy instrument upkeep, fault diagnosis, and leak detection.
Equipped with 24 sample positions and a 7-inch capacitive touchscreen interface.
Utilizes semiconductor refrigeration to optimize cost efficiency.
Cold trap temperature can reach as low as -35°C (depending on ambient temperature).
Operates with motor-driven mechanisms, eliminating the need for external gas drive.
Fully automates processes such as enrichment and sampling.
Gas lines are constructed using passivated and polished 316 stainless steel, with sealing rings made of PTFE material for high temperature resistance and no volatile emissions. Sample gas lines utilize passivated stainless steel tubes treated with RESTEK, Siltek®, or Sulfinert®, complemented by stainless steel ferrules and fully heated.
Features stainless steel tapered needle sampling, with side apertures for increased strength and extended use of sampling pads.
Integrated standard sample simulation sampling functionality.
Compatible with a wide range of GC and GC-MS systems.
Capable of synchronizing startup with chromatographs and workstations, and receiving chromatograph-ready signals for seamless integration and collaboration.
