Reference standard:
GB/T 17623-1998 "Determination of dissolved gas components in insulating oil by gas chromatography"
GB/T 7252-2001 "Guidelines for Analysis and Determination of Dissolved Gases in Transformer Oil"

Instrument features:
New networked control and transmission to achieve real-time monitoring and data collection by multiple people:
The GC6600 transformer oil gas chromatograph adopts the 10/100M adaptive Ethernet communication interface of technology * and built-in IP protocol stack. After setting the PI address of the instrument, the chromatograph can be accessed remotely through the network, so that the instrument can control the chromatograph work and collect the data transmission of the spectrogram remotely through the enterprise's internal LAN and the Internet; Three independent connection processes are designed inside the instrument, which can be connected to the local processing (laboratory technician), unit supervisor (team leader), and superior supervisor (special duty, chief engineer, etc.) through the Internet, which can facilitate multiple people to monitor the operation of the instrument and analyze the data results in real time, and improve the cooperation and timeliness of work.
Multiple workstations are controlled, enabling one computer to simultaneously monitor N gas chromatographs
The NETChromTM workstation equipped on the GC-6600 instrument can support multiple chromatographs to simultaneously process and control data, reaching the industry's highest level, effectively solving the problem of too many laboratory computers and freeing up experimental space.
3. Electronic pressure display, accurate adjustment, and display of various gas flow rates
GC-6600 * abandons traditional mechanical valves and pointer pressure gauges, and installs an electronic flow display system for gas path control, accurately controlling, adjusting, and displaying gas path flow, eliminating the interference of injection peaks on hydrogen gas. The automation level and overall performance of its instruments have been significantly improved.
⦁ Adopting a mature three detector process to separate all components
The GC-6600 transformer oil spectrophotometer is equipped with mature three detector process technology, TCD detector and two FID detectors * in combination, to complete the separation of seven components: H2, CO, CO2, CH4, C2H4, C2H6, and C2H2 *. FID1 is used in conjunction with nickel catalyst conversion to detect CO and CO2, while FID2 detects CH4, C2H4, C2H6, and C2H2, eliminating mutual interference and shortening detection time, while greatly improving detection sensitivity.
Automated control of ⦁ *, workstation protection program of *
The GC-6600 transformer oil and gas chromatography is equipped with software that implements dual protection measures for flow control and temperature control, as well as over temperature protection and gas cut-off protection. Greatly avoiding experimental safety hazards, in line with the most important production safety principles.
