Main functions and features

1. Strong universal performance: can be used in combination with any brand of gas chromatograph (GC) and (GC-MS)

2. Easy to operate and highly automated: simply place the sample bottle in the sample tray, and other operating software will complete it, so the experiment has good repeatability; The host is equipped with a large size

Touch LCD screen, rich interface information, fully tracking temperature and operation commands throughout the process

3. The cold trap adopts semiconductor cooling and air cooling, with a low cooling temperature of up to -40 ℃ (at room temperature of 20 ℃)

4. The heating of the capture tube is achieved through direct resistance heating, with a heating rate greater than 3000 ℃/min

5. The built-in foam sensor can detect the foam in the purging pipe, prevent the way of polluting the sample, and protect the entire analysis system

6. Users can customize the cleaning frequency of the sampling needle and blowing tube

7. Solid sample bottles can be heated and directly injected with distilled water for oscillation, mixing, and blowing

8. The gas separation between the capture tube and the blowback tube reduces cross contamination between samples. In the blowback cycle, compounds blown out of the capture trap will not flow into the blowback

9. The water trap removes water vapor at the blowing end, greatly reducing the impact of water vapor on GC and GC/MS

10. The sample tubing is made of PEEK material and treated with silane inert stainless steel to reduce residual pollution

11. All pipelines and six way valves are temperature controlled for heating, eliminating system cold spots and reducing sample loss

12. Provide a synchronization interface that can start both the chromatography and workstation simultaneously during sample injection

Common application areas

By combining with GC or GC/MS, it can be widely applied in environmental analysis, such as the analysis of organic pollutants in drinking water, wastewater, and soil, as well as the analysis of volatile compounds (such as odor components) in food.
