working principle

AS-12 multifunctional gas automatic samplerThe sample is steadily and uniformly passed through the quantitative loop using a constant flow pump. The flow rate is precisely controlled using a mass flow meter, and the quantitative loop is filled at a constant speed. After completion, the 10 (6) valve is switched to inject the sample into the chromatographic column for analysis. The quantitative loop and sample transfer line can be heated and temperature controlled. Main parameter indicators:

1. Input power supply voltage: single-phase AC220V ± 10%, 20Hz

2. Power: 0.5KW (AC)

3. Standard gas flow range: 0~100ml/min

4. Nitrogen flow range: 0~500ml/min

5. Single stage maximum dilution factor: 500 times

6. Injection volume: 1ml (can replace quantitative rings of different volumes such as 1, 3, 5ml, etc.)

7. Automatic sample injection position: 12 positions

8. Number of injection positions for standard samples: 1

9. Sampling time range: 0~999 seconds

10. Operating temperature range: room temperature -50C11, injection method: six way valve quantitative ring injection

12. Sample dilution function; Can automatically complete sample dilution and automatic injection, with secondary sample

Dilution function, can easily dilute samples up to ten thousand times in multiple stages

13. Operating software: Dedicated workstation software that can be operated through a touch screen and remotely controlled through a PC. 14. Heating function of transmission line and quantitative ring: The sample transmission line, valve, and quantitative ring can all be heated,

Ensure that there are no cold spots throughout the entire sample transfer process

15. Transmission line temperature range: room temperature -180 ℃ Valve and quantitative loop temperature: room temperature -150 ℃ 16. Automatic configuration standard curve function: multiple standard concentration points can be injected in sequence at once, up to

Set 12 standard curve points

17. Automatic sample pipeline cleaning function: After injection is completed, the sample pipeline can be automatically cleaned

18. Backblowing and pre blowing function: Before injection, nitrogen can be used to back blow the injection pipeline and pre blow the sample

Rinse the sample pipeline

19. Using ceramic sample valve, no adsorption or residue
