HZSV-7910AType fully automatic headspace sampler

1、 Instrument Introduction

HZSV-The 7910A fully automatic headspace sampler isIThe company has recently developed and launched a new generation of fully automatic headspace sampler with more convenient operation and higher cost-effectiveness.

2、 Characteristics and main functions of the instrument

1. It can automatically run up to 10 samples without the need for personnel on duty;

2. Power on self-test, fault alarm and prompt, automatic positioning of sample tray;

3. Microcomputer program control, with main functions including:

⑴ Method parameter setting, real-time animation display of working status, and running time;

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

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

⑷ It has multiple expansion functions: dynamic headspace, purge and capture, low-temperature cold trap;

⑸ The GC and chromatographic data processing workstations can be started synchronously, and the device can also be started using external programs;

4. Equipped with an external carrier gas regulation system, the GC instrument can be used for headspace sampling analysis without any modifications or changes. 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. Adopting pressure equilibrium injection technology, the peak shape of headspace injection is narrow and the repeatability is good;

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

8. In order to make it more convenient and accurate to use with imported gas chromatographs, this instrument is also equipped with dedicated interfaces for various imported instruments, which are easy to connect;

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

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