GC126B Gas chromatograph

GC126B Gas chromatograph 

Introduction
      The newly designed GC126 gas chromatograph , using the international advanced control technology . High temperature accuracy ( better than ± 0.1 ℃) superior reliability and robustness. Control and use the keyboard to set the various parameters , the machine has a self- diagnosis , power protection , file storage and call , extreme temperature setting and other functions. 3.8 " large screen can accurately display the brightest temperature setpoint, actual value and real-time curve , each detector parameters , the signal value and its real-time curve . Control area has six independent : the oven , injector , detector, aids . The product can achieve nine bands temperature program , after the oven has automatic cooling function that is open to achieve rapid heating and rapid cooling . Instrument base with a double and a single type of high sensitivity hydrogen flame ionization detector (FID), one of the following optional detectors, gas sampling valve , reformer and other accessories can also install two detectors and detection high sensitivity ( e.g. FID test results for : DFID≤4 × 10-12g / s), the settling time is short, easy cleaning and nozzle mounting

Features :

     Embedded 32-bit processor and multi- CPU systems development, IT interface-related technology, automatic temperature parameter settings, select the detector , the detector operating parameters and data of the auto-zero function , sensitivity and polarity of digital settings.
Full Chinese menu interface , and can display multiple sets of parameters , the operation is very simple and convenient.
Computer anti-control function , you can operate the instrument all the features inside the computer ( via USB interface ) No external workstation and provides an analog output interface.
