1. The composite filling adsorption tube has good adsorption performance for different types of target compounds, with a large sampling volume of up to 1L or more;
2. Rapid flash evaporation technology, with a high heating rate of up to 40 ° C/s in the adsorption tube, ensures a narrow injection band width;
3. Adopting pre column/back blowing technology to retain target components and blow back high boiling point components in the sample not only shortens the total analysis time, but also extends the service life of the analysis column and reduces operation and maintenance costs,
4. The analysis flow path adopts deactivated and passivated pipelines and devices, which have no adsorption on the sample and accurate star measurement results,
5. Use automatic electronic flow control technology (EPC) to control the carrier gas, air, and hydrogen with high precision (0.01psi), Good repeatability and reproducibility,
6. The core components are all made of well-known brands, with high reliability and long service life.
