Features Computer aided temperature control with high accuracy (less than ±0.1°C) All control and application parameters, including operation parameters of the detector, can be set up through the keyboard. Functions, such as self-diagnosis, switch-off protection, document storage and transaction, limit temperature setup thermal trip valve setup, and FID auto-ignition are incorporated inside of the instrument. Large-screen LCD display, can accurately and clearly present all temperature control setup values, actual values, TCD working electricity supply, sensitivity of FID magnifier, and etc. The instrument supports packed column i.e. on-column sample injection. It is compatible with such devices as instantaneous vaporizing sample injection, gas sample injection with gas sample injection valves, and 0.53mm large diameter capillary column direct sampler. Open-end computer system can apply RS-232 interface and FJ-2000 chromatogram workstation to achieve dual path communication control and data processing. Large capacity column (300mm×280mm×270mm) is easy to install together with packed column and large diameter capillary column.
