Performance characteristics

1 Strong applicability of the three-stage cold trap method

Adopting the rapid sample transfer mode, the VOCs in the focusing trap enter the chromatographic column quickly. 色谱柱， 在柱子管内传输时实现二次聚焦， 从而能够保证峰形更 加锐利。 The system is compatible with HJ759-2015, and can analyze 117 VOCs in ambient air, indoor air, pollutant exhaust, and other scenarios, especially 13   aldehydes and ketones with higher analytical efficiencies. lt;p>系统内置定量环，高达 1000 倍以上的浓缩率，满足高浓度样品分析的进样应用需求，有效提升分析仪器检测下限，精度优 于国家标准。

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 autosamplers, to achieve unattended sampling work. Easy to operate, record process data, report and print to support quality control.

4 Compatible and powerful

Compatible with imported or domestic canisters and gas bags, compatible with the mainstream GC or GC-MS on the market; Independent 4-way sampling, can be connected to multiple autosamplers; Can be used to create unique analytical methods based on the characteristics of compounds on the preset analytical methods. The analyzer can be connected to multiple autosamplers.

5 Stable operation and intelligent baking

The composition of the gas path is more abundant, flexible and changeable, which is more adaptable to more advanced analytical methods. In addition, the gas path switching and time control are more accurate and reasonable. The rich gas path changes, precise control can greatly improve the accuracy of the instrument. 5min before the end of the GC delay time, preheat the cold trap 3 baking, remove residual water to ensure the consistency of each baking, to avoid the impact of impurities, water on the system and the results of the analysis, and improve the stability of the analysis.

6 deep-cooling technology application

Unique liquid nitrogen cooling module technology, liquid nitrogen cooling can be directly to the core of the trap, to achieve rapid cooling, improve the cooling rate and temperature control sensitivity, and reduce the consumption of liquid nitrogen. The deep-cooling technology can be used to analyze the determination of 8 kinds of sulfur-containing organic compounds.
