Fully Automatic Headspace Sampler, HS-40 (CAT#: STEM-C-2749-ZJF)

HS-40 is equipped with 40 sample positions, with the capability to concurrently heat 12 samples. It adopts the same air bath heating method as the chromatographic column box, ensuring uniform heating. Three vibration modes are available to shorten the heating time. After sample injection, the sample vial returns to its original position, protecting rare samples. The instrument can store multiple methods for convenient use. It finds wide applications, including but not limited to: alcohol detection in blood; residual solvent analysis in drugs, packaging materials, and medical devices; detection of volatile organic compounds in environmental soil, sediment, and water bodies; fragrance detection in food and beverages, and flavor detection in cosmetics.

Equipped with an upper computer interface and dedicated PC control software, allowing users to monitor the headspace operation status through the workstation and operate the headspace sampler via the workstation or third-party software.
Features a 7-inch capacitive touchscreen, enabling users to perform all operations of the headspace sampler directly on the screen.
Simplified operation with one-touch startup, automating heating balance, injection, sampling, initiating chromatography and workstation, and bottle replacement, achieving complete process automation.
Pre-installed with multiple analysis methods, which can be directly accessed or modified as needed.
Pre-settable with 40 samples, allowing simultaneous heating of up to 12 samples, significantly improving work efficiency. Microcomputer precision control ensures consistent heating time for each sample. The air bath heating method ensures uniform heating, enhancing sample accuracy compared to traditional metal bath methods.
Incorporates multiple fault detection and handling modes, automatically halting operation and providing prompts in case of mechanical movement anomalies to ensure reliable high-precision movement and prevent bottle collisions. Maintenance mode allows for easy instrument maintenance, fault diagnosis, and leakage detection.
After sampling, the sample vials return to their original positions, maximizing the protection of rare samples and facilitating traceability.
All sample transfer pipelines and quantitative loops utilize RESTEK passivation, Siltek®/Sulfinert® treated 316L stainless steel tubes, leaving no residue and ensuring the transmission of polar compounds, acidic substances, and sulfides without cross-contamination, thereby guaranteeing sample repeatability and accuracy.
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 preserving 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.
Comes standard with a pressure cap clamp and 100 sets of imported sample bottles, facilitating user operation and reducing costs.
Features an integrated design with a compact structure, constructed of aluminum alloy, ensuring rigidity while significantly reducing weight, and guaranteeing transportation safety. Microcomputer control, full Chinese LCD display, and simple operation enhance user convenience.
Demonstrates strong compatibility, easily connecting with all types of gas chromatographs and gas-mass spectrometry systems, with quick and easy interface connection. Simply connect the carrier gas and insert the transport pipeline into the GC sampler inlet. It can synchronize startup with chromatography and workstations and read chromatographic readiness signals, collaborating effectively with chromatography.
