Introduction: HS-A901 series full-automatic headspace sampler is a sample pre-processing device developed by our company with full-automatic function, industrial-grade touch screen display, compact structure, and convenient human-computer interaction. The principle is to place the sample to be tested in a closed container, heat and increase the temperature to make the volatile components in the sample to be tested volatilize from the sample matrix, after reaching equilibrium, directly extract the upper gas and send it to post-processing equipment such as gas chromatography Perform analysis to detect the composition and content of volatile components in the sample. Features: 1 Fully automatic system is safe and reliable 2 Modular design of software and hardware, compact structure 3 The industrial-grade touch screen interface is rich in information, man-machine interaction is simple, easy to operate, and has the following functions: 1) The information displayed on the LCD screen includes: multi-method parameter settings, real-time working status, running process and time, etc. 2) The headspace bottle, the sampling system and the sampling (injection) catheter are unified and coordinated through the touch screen to achieve three-way heating and temperature control 3) 10 methods for editing, storing and recalling at any time 4) The GC and chromatographic data processing workstations can be started synchronously, and the device can also be started by an external event program to realize repeated injections of the same sample bottle 5) With self-check function (board level and gas circuit) and fault display function 4 With sample bottle shaking function, shorten the balance time, improve sensitivity and repeatability 5 The combination of six-port valve and quantitative ring effectively reduces dead volume and improves analysis sensitivity 6 The six-way valve and the transmission pipeline link have no transmission cold spots, ensuring the integrity of the sample 7 Support time progressive mode 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 headspace furnace workers: 1 or 3 Headspace bottle station: 12/24/30 station optional, upgradeable 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) Power supply: AC220V 50Hz Power: 500W Instrument size: 650×380×620mm3 Instrument weight: about 40kg
