GC102AF and GC102AT gas chromatographsDetailed product description：

1、 Product Description:
GC102AF and GC102AT gas chromatographs are microcomputer based, newly designed single detector universal gas chromatographs. GC102AF is a gas chromatograph equipped with a single hydrogen flame ionization detector (FID); GC102AT is a gas chromatograph equipped with a thermal conductivity detector (TCD).

2、 Characteristics:
1. Microcomputer based temperature control with high temperature control accuracy (better than ± 0.10C).
2. The keyboard is used to set various control and usage parameters (including detector operation parameters), and the machine has functions such as self diagnosis, power-off protection, file storage and retrieval, extreme temperature setting, and FID automatic ignition.
3. The large screen Chinese character LCD display has a large amount of information and is intuitive and easy to understand. It can accurately display various temperature control settings, actual values, TCD working current, FID amplifier sensitivity, etc.
4. The instrument can achieve filling the column for sampling. Optional options include instantaneous vaporization injection, gas injection, and gas injection valve, as well as a 0.53mm large-diameter capillary column direct sampler.
5. The open microcomputer system can be optionally paired with RS-232 interface and FJ-2000 chromatography workstation to achieve bidirectional communication control and data processing.
6. The large capacity column box (300mm × 280mm × 270mm) is convenient for installing packed columns or large-diameter capillary columns.
