Introduction: HS-951M series semi-automatic headspace sampler is a semi-automatic headspace sampler developed by our company with large touch screen display, compact structure, convenient human-computer interaction, high quality and low price. In order to ensure the consistency of the experiment and simplify the process of piercing the sample needle by the experimenter, this product adopts the automatic piercing method of the sample needle, and only needs to manually rotate the sample tray. Features: 1. Automatic needle injection: reduce manual operation and reduce manual error 2. Exquisite design: This instrument has been carefully designed, with a simple and generous appearance 3. Economical and durable: the instrument components are stable and durable after long-term inspection 4. Low residue adsorption: the whole pipeline is made of inert materials, and the whole pipeline is heated and insulated 5. Strong versatility: it can be directly connected to any domestic and foreign instruments, easy to use 6. Automatic six-way valve: to ensure consistent sample injection 7. The large touch screen interface is rich in information, simple in human-computer interaction, easy to operate, and has the following functions: 8. 10 methods for editing, storing and recalling at any time 9. The GC and chromatographic data processing workstations can be started synchronously, and the device can also be started by an external event program to achieve repeated injections of the same sample bottle. 10. With self-check function (board level and gas circuit) and fault display function Technical parameter: Temperature control range of headspace furnace: room temperature～260℃, step length 1℃ Temperature control range of valve sampling system: room temperature～220℃, step length 1℃ Temperature control range of sample transfer pipeline: room temperature～220℃, step length 1℃ Temperature control accuracy: <±0.1℃ Temperature control gradient: <±0.1℃ Number of heating stations: 12 Headspace bottle station: 12 Headspace bottle specifications: standard 20ml (10ml and other specifications can be customized) Injection pressure range: 0～0.4Mpa, continuously adjustable Monitoring pressure range: 0～0.4Mpa, pressure gauge display Analysis repeatability: RSD<1.5% (200ppm ethanol aqueous solution, related to GC performance) Power supply: AC220V50Hz Power: 350W Instrument size: 505×295×535mm3 Instrument weight: about 30kg
