5. The vial Specifications : 20 mL ( optional 10 mL )

6. Heating bottles station : 9

7. The injection RSD ≤ 1.5 % ( 0.02 % ethanol aqueous solution , N = 5 )

8. Started simultaneously chromatography data processing station communication interface

l The main features

1. Sampling pump and injection valve, with vacuum sampling ,have no gas dilution affect, high sensitivity and quantitative accuracy;

2. Circumference uniform sample heating, reduce the temperature gradient between the different bottles, increase the stability of analysis results.

3. Injection valve, loop tube and sample transfer tubing to control the temperature, and avoid sample condensation in the transmission ;

4. Sampling lines and the injection valve are equipped with back flush function to prevent cross-contamination ;

5. Single-chip microcomputer control, LCD temperature parameters shows , membrane keyboard input ;

6. Over temperature power off function which safety for use;

7. The injection needle can be freely replaced which is convenient for connections for various types of gas chromatography.

l Instrument introduction

The DK-3001A semi-automatic headspace injector’ sampler vials thermostat furnace adopts circumferential distribution design which is more reasonable, so that to minimize all the top bottles’ heating temperature gradient, improve the stability and reliability of the results analysis. The injection needle is freely to be replaced, convenient for connections for various types of gas chromatography.
