Automatic headspace sampler

HS-12AAutomatic headspace samplerCharacteristics and main functions of

1.Heating and temperature control of metal body, with high temperature control accuracy and small gradient;

2.The pre sample area makes it easier for personnel to operate when placing samples;

3.Microcomputer program control, main functions include:

⑴ Method parameter settings, real-time working status, and running time;

⑵ The sample area, injection valve system, and sample transfer tube are all separately heated and temperature controlled;

⑶ Set the control program and press the run button to automatically complete the entire sample analysis;

⑷ Can store 9 methods for easy calling at any time, achieving fast startup and analysis;

⑸ It can synchronously start GC and chromatographic data processing workstations, and can also be started by external programs;

4.Equipped with an external carrier gas regulation system, headspace injection analysis can be performed without any modifications or changes to the GC instrument. The original instrument carrier gas can also be used;

5.Through time programming, automatic functions such as pressurization, sampling, injection, analysis, and post analysis blowback cleaning can be achieved;

6.The use of pressure equilibrium injection technique for headspace injection can obtain narrow chromatographic peak shapes;

7.The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;

8.For active substance analysis, an elastic quartz tube can be selected as the sample transfer tube;

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

10.The injection needle is easy to replace and can be connected to all models of GC injection ports at home and abroad.
