GX-1000 Gas Chromatograph

Characteristics and performance:
_A completely new design of microcomputer temperature control system has adopted international advanced control technology. The temperature control accuracy is high (better than (+0.05 C) and the reliability and anti-interference performance are superior.
_The health disk sets various control and use parameters (including detector operating parameters), and has functions of self-diagnosis, power-off protection, file storage and invocation, limit temperature setting, etc. It can accurately display the temperature control setting value, actual value, TCD bridge current, FID amplifier sensitivity, retention and analysis time, etc.
There are five independent control areas: column box, sampler, detector, thermal conductivity pool and auxiliary device.
The product can realize five-order program heating, with the function of automatic cooling of column box and back door opening, to achieve rapid cooling.
The product can easily install filling column and capillary column (0.53 large-caliber column or small-caliber column), and there is a complete set of capillary diversion injection joint and tail-blown joint in the accessories (without additional payment). Diversion/non-diversion injector and 0.53mm large caliber capillary column direct injector are optional.
_The instrument can be used for filling column analysis or capillary column analysis, and can realize various injection methods.
Filling column: column injection, instantaneous vaporization injection, gas injection; capillary column: split injection, non-split injection, 0.53 large diameter column direct injection.
_The instrument has the structure of double gas path, double sampler and double packed column system. It can effectively suppress baseline fluctuation and drift in real time, and is suitable for temperature programmed analysis. Precise calibrated air control valve with high reproducibility and stability.
