Equipped with an upper computer interface and dedicated control software, allowing monitoring of the headspace operation status through the workstation and enabling operation of the headspace sampler via the workstation or third-party software.
Features a full Chinese LCD display for easy operation with one-touch startup. It facilitates fully automated processes including automatic heating balance, shaking, injection, sampling, initiating chromatography, workstation startup, and bottle replacement, achieving complete process automation.
Pre-settable with 15 samples, enhancing the reliability and consistency of analysis without requiring manual intervention.
Offers three intensity levels of shaking modes to aid rapid sample equilibration, thereby improving analysis efficiency.
Incorporates multiple fault detection and handling modes. It automatically identifies the position of sample vials, avoiding collisions with uninstalled vials. In case of positional faults, it prevents bottle collisions and automatically halts operation upon mechanical movement anomalies, effectively ensuring reliable and damage-free high-precision movement.
All sample transfer pipelines and quantitative loops utilize RESTEK passivated, Siltek®/Sulfinert® treated 316L stainless steel tubes. These tubes leave no residue, facilitating the transmission of polar compounds, acidic substances, and sulfides without cross-contamination. The combination of six-way valves and quantitative loops minimizes dead volume, ensuring sampling accuracy. The connection points between the six-way valve and the transmission pipelines are located within a heated insulation box, eliminating transmission cold spots and guaranteeing sample integrity.
Adopts the classic positive pressure sampling method, suitable for liquid or solid samples, with high detection sensitivity. Atmospheric pressure injection ensures baseline stability, capable of detecting benzene in water at 1 ppb.
All actions are driven by motors, eliminating the need for external driving gases and ensuring safe and convenient operation.
Features an integrated design with a compact structure. The entire machine is constructed of aluminum alloy, ensuring rigidity while significantly reducing weight, ensuring safe transportation. Microcomputer control, full Chinese LCD display, and easy operation further enhance user convenience.
Comes standard with a pressure cap clamp and 100 sets of imported sample bottles, facilitating user operation and reducing costs.
Demonstrates strong compatibility, easily connecting with various gas chromatographs domestically and internationally. It can synchronize startup with chromatography and workstations, read chromatographic readiness signals, and collaborate with chromatography.
