Performance characteristics

1 three-stage cold trap method applicable

Adopting the rapid sample transfer mode, the VOCs in the focusing trap enter the column quickly and achieve secondary focusing when transferring in the column tube, thus ensuring a sharper peak shape.

2 Wide applicability of high and low concentration

The system has a built-in dosing ring with a concentration rate of up to 1000x or more, which is ideal for analyzing high concentration samples. The system has a built-in quantitative ring, up to 1000 times the concentration rate, to meet the high concentration of samples analyzed by the injection application needs, effectively improve the detection limit of analytical instruments, accuracy better than the national standard.

3 Fully automated sampling

Sequence editing, automatic system operation, automatic error reporting. The number of samples is higher than 19, can be connected to 4 autosampler, to achieve unattended sampling work. It is easy to operate, records process data, and can report and print to support quality control.

4 good compatibility, powerful

Can be paired with imported or domestic sampling canisters, gas bags, compatible with the market mainstream GC or GC-MS; can be independent of the 4-way injection, can be connected to a number of groups of autosampler; can be in the preset analytical methods according to the characteristics of the compounds to establish the application of the unique analysis method. The analytical method can be applied on the preset analytical method according to the characteristics of the compounds to establish the unique analytical method.

5 Stable operation, intelligent baking

The composition of the gas path is richer, more flexible, more variable, more adaptable to more advanced analytical methods. It is also more accurate and reasonable in gas path switching and time control. Rich gas path changes, precise control can greatly enhance the accuracy of the instrument. 5min before the end of the GC delay time to reach the end of the pre-heating of the cold trap 3 baking, to remove residual water to ensure the consistency of each baking, to avoid impurities, water on the system and the analysis of the results of the impact of the analytical stability at the same time improved.  

6 Analysis of low cost

New electronic cooling module technology, free of the traditional liquid nitrogen cooling capture VOCs technology. This makes the analytical workflow simpler and saves on consumables and improves work efficiency.
