GC-8890 portable gas chromatograph Introduction: GC-8890 Transformer Oil Chromatography Instrument is a high-performance chromatograph that is networked, fully reverse controlled, and has automatic control of gas path pressure and flow rate. By using a ten way valve to automatically cut and blow back, all nine gas components dissolved in transformer oil, including hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, methane, ethylene, ethane, and acetylene, can be measured in one injection. characteristic: 1. The 10/100M adaptive Internet communication technology can be used to form a LAN and realize long-distance data transmission. 2. Reliable anti control technology, all instrument parameters can be remotely set through a computer and subjected to general image processing. 3. Digitally control all parameters of the gas path (flow and pressure), with three working modes: constant current, constant pressure, and split current. 4. Various parameter settings and operations of the instrument can be set using a beautiful and elegant touch screen or computer. 5. High performance detectors and methane converters with detection capabilities that meet the requirements of the Ministry of Electric Power for measuring gas content in transformer oil. 6. Adopting a new type of column packing and a dual column temperature process, the detection time of C2H2 is advanced, the sensitivity is high, and the analysis cycle is shortened. 7. It has automatic ignition and automatic detection and extinguishing functions. Technical parameters: 1.
