With the development of science and technology, the technology of hydrogen flame chromatographic detector has also been greatly improved, such as the minimum detection concentration of hydrogen flame detector is getting smaller and smaller. The improvement of the technical indicators of hydrogen flame chromatographic detector has enabled it to be more widely used on the one hand, but it also brings certain problems to the instrument detection work on the other hand. When testing the minimum concentration and other technical indicators of hydrogen flame detector, the traditional detection method usually adopts the method of artificial gas preparation, and its sample preparation uncertainty and large subjective error become the main part of the system error. This article starts with the introduction of the working principle of hydrogen flame detector. On the basis of analyzing the traditional detection method, it proposes to use the gas preparation instrument to realize automatic sample preparation, so as to achieve the purpose of effectively detecting the technical indicators of hydrogen flame detector. Keywords: hydrogen flame detector principle gas preparation instrument detection technology detection method hydrogen flame detector plays an important role in the process of oil and gas exploration, and is an important tool for judging and identifying the properties of oil and gas layers. Its development trend is: the minimum detection concentration is getting smaller and smaller, and the chromatograph analysis cycle is constantly shortened. For example, the minimum detectable concentration of hydrocarbon components in the SK-3Q02 hydrogen flame detector produced by Shanghai Shenkai Instrument Factory is 0.003%, and the minimum detectable concentration of hydrocarbon components in the SK-3Q04 hydrogen flame detector is 0.0001%; the minimum detectable concentration of hydrocarbon components in the GEO6000 hydrogen flame detector produced by Geoservices of France is 0.001%; the minimum detectable concentration of hydrocarbon components in the HP6890 hydrogen flame detector produced by Agilent is ≤0.0005%. However, the rapid development of hydrogen flame detector technology has also brought certain challenges to instrument detection work, especially when detecting the minimum detectable concentration and the measurement repeatability of the instrument, the traditional manual sample matching error greatly affects the measurement system error of the instrument. In view of the above problems, it is necessary to study the detection method of the technical indicators of the hydrogen flame detector. The purpose is to develop a set of automatic gas matching devices to replace manual gas matching and reduce the influence of sample matching errors on system errors; the second is to explore a set of inspection methods suitable for hydrogen flame detectors to improve the detection quality. At the same time, the research and development of hydrogen flame detectors in the petroleum industry has become the only way for petroleum enterprises to develop. The detection of hydrogen flame detector technical indicators is also an important link in the process of instrument development and subsequent use, and it is necessary to grasp the technical performance indicators of the instrument. The research on the detection method of hydrogen flame detector technical indicators is helpful to form its own characteristics in the research and development of research and instrument matching, and in the research and development of instruments. It is necessary to improve the professional technical level of the petroleum industry and enhance market competitiveness.
