2． Equipment Usage Description

2.1 Used for pre-treatment of liquid and solid samples, and combined with gas chromatography or gas chromatography-mass spectrometry to achieve qualitative and quantitative analysis of trace or constant volatile organic compounds in liquid and solid samples.

3. Main technical indicators

3.1 Standard configuration includes a 45 position sample tray (optional from 45 to 90 positions), a sampling dual three-axis motion platform, and independent bottle picking and needle tying, which improves sample making speed and enhances bottle and furnace expansion capabilities;

3.2 The PC control interface intuitively displays the dynamic diagram of instrument operation, allowing real-time monitoring of instrument operation and the current status of each sample; Editable methods and sequences, capable of running a single method or multiple methods, and can be set to a common language including Chinese;

3.3 The headspace sampler adopts pressure equilibrium time injection technology, with only one metal injection needle in the injection flow path, and no metal components such as the six way valve and quantification ring that are prone to adsorb residual substances;

3.4 The headspace sampler uses a fully enclosed transmission system to transfer the sample to the gas chromatography injection port through a transmission pipeline, with no diffusion during the injection process; No carrier gas dilution;

3.5 Injection volume control mode: Time injection mode and volume injection mode can be switched directly on the touch screen or software. The injection volume can be set through parameter settings without the need to replace the hardware quantification ring, etc;

3.6 The self checking, fault alarm and prompt functions of the startup system, temperature overload protection function, leakage protection function, etc. have increased the safety factor of instrument use;

3.7 Multiple specifications of headspace sample bottles such as 10ml and 20ml can be used;

3.8 The control software can form a queue of discontinuous multiple sample grades, achieve skip position combination, and adjust the priority order of the sample queue for emergency sample analysis;

3.9 Equipped with dedicated interfaces, it can be used in conjunction with various models of gas chromatographs or gas chromatographs both domestically and internationally;

3.10 The heating position has oscillation function, which can reduce the time required for the sample to reach equilibrium and improve the efficiency of sample preparation;

3.11 Needle heating function to avoid sample condensation and increase experimental accuracy;

3.12 The sample transmission pipeline and injection needle are made of inert materials to prevent sample residue and loss;

3.13 The connection modes with gas chromatography include: injection port connection, two-way connection, and reverse serial connection;

3.14 Equipped with a zero dilution liner (optional for positions 45 to 90), it can completely eliminate carrier gas dilution during headspace injection;

The 3.15 injection system has an automatic blowback function, which can effectively reduce cross contamination of different samples;

3.16 The length of the transmission line can be selected according to actual usage, making it convenient for multiple devices to connect and use;

3.17 Optional electronic pressure control (EPC) system can be used to reduce manual errors, improve analysis accuracy and reproducibility;

3.18 Headspace injection reproducibility, RSD of ethanol in water ≤ 1.0% (N=10);
