Overview
The instrument can detect components such as hydrogen, carbon monoxide, carbon dioxide, methane, ethylene, ethane, acetylene, and GC-9800 transformer oil specific chromatograph. It is a newly launched specialized gas chromatograph by Jingce Company for the determination of dissolved gas components in insulating oil for power use. The instrument adopts a three detector process, equipped with TCD detector and two FID detectors. With one injection, the full analysis of the content of seven dissolved gas components in insulating oil can be completed within 7 minutes. Among them, H2 was detected by TCD; Hydrocarbon gases (CH4, C2H4, C2H6, C2H2) are detected by FID1, while CO and CO2 are detected by FID2, overcoming the impact of a large amount of CO and CO2 on hydrocarbon gases, especially on C2H2. This not only shortens the detection time but also greatly improves the detection sensitivity.

GC-9800Oil Chromatographic Analysis System for Power Transformers The determination of dissolved gas content in insulating oil by gas chromatography is an effective means for power generation and supply enterprises to determine whether there are latent overheating, discharge and other faults in oil filled power equipment during operation, in order to ensure the safe and effective operation of the power grid. It is also an important means for oil filled electrical equipment manufacturers to conduct factory inspections on their equipment GC-9800The transformer oil specific gas chromatograph is a newly launched specialized gas chromatograph by Jingce Company for the determination of dissolved gas components in insulation oil for power use. The instrument adopts a three detector process, equipped with TCD detector and two FID detectors. With one injection, the full analysis of the content of seven gas components dissolved in insulation oil can be completed within 7 minutes.

Specialized chromatographic workstation for transformer insulation oil analysisIntroduction
The calculation method complies with GB/T 7252-2001 and DL/T 722-2000.
Automatically provide three ratio coding, fault nature, and typical examples in the report.
The management of oil sample spectrum library can be achieved by sampling points (creating, adding, deleting, modifying, querying, sorting).
Generate equipment analysis file cards based on the analysis results of the same device, automatically completing calculations such as total hydrocarbon growth and gas production rate.
The trend curve of the content of each gas component over time can be made for the same sampling point.
Multiple sample analysis results can be consolidated into one report, and the average, standard deviation, and relative standard deviation (RSD) of these results can be provided.
Spectral peak intelligent identification technology greatly reduces the need for user set spectral processing parameters, and basically achieves automatic processing of peak detection, baseline correction, and overlapping peak segmentation.
Provide the function of manually cutting shoulder peaks (small bulges) accurately from trailing peaks for quantitative analysis of trace components.
The spectrum file (including analysis results) can be sent over the Internet to higher-level units or supervisory departments for analysis and review through the "send" function.
Quantitative results, explanatory text, etc. can be directly entered into the Access database.
The effective parts of two channel spectra can be grafted onto one spectrum, and ultimately only one spectrum needs to be processed, calculated, and saved.
Using split window technology, tables and spectra are displayed in the same document window, and the table arrangement adopts an intuitive and easy-to-use tab format, avoiding the need to switch back and forth between different screen interfaces during operation. The interface layout is compact and the operation is very simple.
