Factory wholesale Paper Shaper - DK-9000 Headspace sampler–semi-automatic – Yueyang

DK-9000 automatic headspace sampler is a headspace sampler with six-way valve, quantitative ring pressure balance injection and 12 sample bottle capacity.It has unique technical characteristics such as good universality, simple operation and good reproducibility of analysis results. With durable structure and simplified design, it is suitable for continuous operation in almost any environment.

DK-9000 headspace sampler is a convenient, economical and durable headspace device, which can analyze volatile compounds in almost any matrix.It is widely used in (solvent residue detection), petrochemical industry, fine chemical industry, Environmental Science (drinking water, industrial water), food industry (packaging residue), forensic identification, cosmetics, drugs, spices, health and epidemic prevention, medical supplies and other samples.

1. It is applicable to the interface of any gas chromatograph. It is convenient to replace the injection needle. It can be connected to all types of GC injection ports at home and abroad to achieve maximum flexibility.

2. Microcomputer control, LCD display and touch keyboard make the operation more convenient

3. LCD screen display: real-time dynamic display of working status, method parameter setting, operation countdown, etc

4. 3Road events, programmable automatic operation, can store 100 methods and call them at any time, so as to realize rapid startup and analysis

5. The GC and chromatographic data processing workstation can be started synchronously, and the device can also be started with external programs

6. Metal body heating temperature control, high temperature control precision and small gradient;

7. Sample heating method: constant heating time, one sample bottle at a time, so that samples with the same parameters can be treated exactly the same.The 12 sample bottles can also be heated in turn to shorten the detection time and improve the analysis efficiency.

8. The six way valve quantitative ring pressure balance injection technology is adopted, and the peak shape of headspace injection is narrow and the repeatability is good

9.Three independent heating and temperature control of sample bottle, six way valve injection system and transmission line

10. Equipped with additional carrier gas regulation system, headspace injection analysis can be carried out without any modification and change of GC instrument.The carrier gas of the original instrument can also be selected;

11. The sample transfer pipe and injection valve have automatic back blowing function, which can automatically back blow and clean after injection, so as to avoid cross pollution of different samples.
