Product Description

LCHS-20N Automatic Headspace Sampler Device Oil Gas Chromatograph Autosampler 

Features:

1. 7-inch touch color screen is adopted to automatically realize pressure, sampling, sampling, analysis, backblow cleaning and other functions through time programming;

2. The number of headspace bottle stations is as many as 20, with fast heating speed, high temperature control precision and small gradient;

3. The screen displays the status of the time process, the status of the work and the function of the work prompt, which greatly facilitates the operation and use of the user;

4. Equipped with external loading gas regulation system, without any modification and change of GC instrument, can be carried out headspace sampling analysis, can also choose the original instrument carrier gas, so that the installation becomes very simple;

5. The pressure balance injection technique was used to realize the symmetrical narrow chromatographic peak shape in headspace injection;

6. Transmission tube and sampling valve have automatic backblowing function to avoid sample residue and cross contamination;

7. For the analysis of active substances, elastic quartz tube can be selected as the sample transfer tube;

8. The injection quantity can be adjusted at any time according to the concentration of the sample to be analyzed by the customer;

9. Convenient syringe needle replacement, can be connected to all types of GC injection ports at home and abroad;

10. The structure design of the machine is reasonable, beautiful, generous and practical;

11. Microcomputer program control, the main functions are:

12. Method parameter setting, real-time working state, three-way temperature control, each running time;

(1) Sample area, sample valve system and sample transmission pipe, three separate heating and temperature control;

(2) Set the control program and press the Start button to finish the whole sample analysis automatically;

(3) The chromatograph can be synchronously started, workstation, can also be used to start the device by external procedures.
