FEATURES

1.Dual FID detectors, optional GCl22-TCD, GCl22-ECD, GCl22-NPD, GCl22-FPD, converter, gas sample inlet valve, etc.

2.Dual packed columns, dual samplers and dual gas path system structure, which can effectively restrain baseline fluctuation and drift in real time, suitable for temperature programming analysis.

3.Can work with 3 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.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 on-column 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.

6.The instrument supports following injection methods:

7.Packed column: on-column sample injection, instantaneous vaporizing sample injection, gas sample injection

8.Capillary column: split injection, split less injection, large diameter column direct injection

9.Newly developed computer aided temperature control system. It can manage the temperature control of six path heating areas at the same time, including column, ion chamber, thermal conductivity detector, capillary column sampler, packed column sampler auxiliary and standby, with high precision (less than ±0.1℃) and wide range (up to 400℃), and temperature overload and deviation is less than 2℃ or even lower.

10.The column has five-phase programmed temperature control, and the highest heating rate is up to 40℃/min.

11.The system has such functions as switch-off protection, temperature limit setup, temperature scanning,rapid automatic cooling, i.e. back opening door, and etc.

12.Open-end computer system can apply RS-232 interface and N-2000 chromatogram workstation to achieve single path communication control and data processing.

13.Large volume full lens stainless column (350mm×280mm×300mm) can support capillary column and dual packed columns at the same time. Inner-placed heating wire structure can facilitate silicon capillary column analysis.
