DC-688 Headspace sampler

DC-688 Headspace samplerIt is a sample pretreatment equipment for gas chromatography, which can quickly and accurately extract volatile compounds from any matrix and transfer them completely to the gas chromatograph. The instrument adopts a 7.0-inch graphic dot matrix color LCD touch display screen, with a friendly interface, clear and concise; The animation display and settings based on the principle of injection can be easily mastered without much effort, making it convenient for users to operate quickly.

DC-688 Headspace samplerKey Features:

1. Full Chinese 7-inch LCD display, easy to operate, one click start. The functions of automatic heating balance, pressurization, sampling, injection, analysis, and blowing after analysis, as well as the replacement of sample bottles, achieve full automation of the process.

2. 20 samples can be pre-set, greatly improving time utilization. No manual intervention is required, improving the reliability and consistency of analysis work.

3. It has complete parameter settings, real-time working status, running time, etc.

4. Comprehensive power on self-test function, automatic positioning of sample tray, automatic alarm for component faults, wiring faults, etc.

5. Multiple injection modes: single bottle multiple times, single bottle single time, multiple bottles single time.

6. There are multiple fault diagnosis and handling modes, which can automatically determine the position of the sample bottle and avoid unfilled positions. In the event of a positional malfunction, it can prevent bottle collision. When mechanical motion is abnormal, it can automatically stop and prompt, effectively ensuring the reliability of high-precision motion and avoiding damage.

7. All sample transfer pipelines and quantitative rings use imported high inertia deactivation pipelines, with no residue or cross contamination, ensuring the repeatability and accuracy of sample injection.

8. The combination of a six way valve and a quantitative loop minimizes dead volume and ensures injection accuracy to the greatest extent possible.

9. The connection point between the six way valve and the transmission pipeline is located inside the heating insulation box, without any transmission cold points, ensuring the integrity of the sample.

10. By using the classic positive pressure sampling method, liquid or solid samples can be measured with high detection sensitivity. Inject at normal pressure without baseline drift.

11. All actions are driven by a motor, without the need for external driving gas, making it safe and convenient to use.

12. Strong compatibility, can be connected to various gas chromatographs at home and abroad, can synchronously start chromatography and workstations, and work together with chromatography. 13. Six way valves with different operating temperatures can be selected according to customer needs.
