Features
1. Newly designed, high performance HRGC
2. Double FID detectors in the basic type with wide accessory options such as GCl22TCD thermal conductivity detector, GCl22ECD electron capture detector, GCl22NPD nitrogen and phosphorous detector, GCl22FPD flame photometric detector, converter, gas sample inlet valve, etc.
3. In the basic type, the instrument has dual packed columns, double samplers and dual gas path system structure, which can effectively restrain baseline fluctuation and drift in real time, suitable for temperature programming analysis. The instrument can work with three types of detectors at the same time. With different detector combination in different application, the instrument can support detectors working in either cascade or paralleled connection.
4. The instrument in the basic type is equipped with completed capillary analysis system and independent capillary split sampler, which includes diaphragm cleaning, split flow and auxiliary gas adjustment. It supports capillary split / split less sampler, cold oncolumn sampler, and 0.53mm large diameter capillary column direct sampler. It's suitable for all kinds of capillary column of various diagrams, speculations, and lengths, and made of glass or flexible silicon glass.
5. The gas path of the instrument adopts high precision scale flow control valve, unloading valve and needle valve. It's easy to adjust flow capability and has better reproducibility and stability
