Automatic headspace samplerTechnical parameters:
Heating range of headspace bottle: 5 ℃ to 200 ℃ above room temperature, set in increments of 1 ℃;
Heating range of injection valve and quantitative loop: 5 ℃ to 160 ℃ above room temperature, set in increments of 1 ℃;
Heating range of sample transfer pipeline: 5 ℃ to 160 ℃ above room temperature, set in increments of 1 ℃;
Injection valve quantitative tube volume: 1mL (optional 0.5mL, 3mL);
Headspace bottle specification: 20 mL (optional 10 mL);
Heating bottle workstation: 16 positions
The RSD of the injection result is ≤ 1.5% (0.02% ethanol aqueous solution, N=5）
Synchronously start the communication interface of the chromatographic data processing workstation

Each product can provide the relative standard deviation (RSD) of chromatographic analysis results at the factory, including corresponding chromatograms and data.

Automatic headspace samplerKey Features:
The sampling pump and injection valve are combined for negative pressure sampling, without the dilution effect of external added gas, with high sensitivity and precise quantification;
A sample heating position uniformly distributed around the circumference reduces the temperature gradient between different bottle positions and improves the stability of analysis results;
The injection valve, quantitative loop, and sample transfer pipeline can control the temperature to avoid sample condensation during transmission;
The sampling pipeline and injection valve are equipped with blowback function to prevent cross contamination;
Single chip microcomputer control, LCD display temperature parameters, and thin film keyboard input;
Overtemperature and power outage protection, safe to use;
The injection needle can be freely replaced, making it convenient to connect various models of gas chromatographs at home and abroad;
