The invention provides an oxygen interference compensation method for an FID detector, comprising: performing single-range point calibration on the FID detector; passing the gas to be measured into the FID detector to obtain the first concentration data of the gas to be measured; The sample gas is passed into the FID detector, and the oxygen interference compensation model is obtained based on the nominal value of the sample gas and the obtained concentration data of the sample gas; the first concentration data of the gas to be measured is input into the oxygen interference compensation model to obtain the gas to be measured The second concentration data; judge whether the ratio of the second concentration data of the gas to be measured to the laboratory standard data is within a preset range, if it exceeds the preset range, update the oxygen interference compensation model, if it does not exceed the preset range, the oxygen interference compensation model is maintained. The method provided by the invention effectively solves the problem that the oxygen interference compensation effect of the single-range point calibration method in the prior art is poor.
Description
technical field [0001] The invention relates to the technical field of gas measurement, in particular to an oxygen interference compensation method for an FID detector. Background technique [0002] At present, there are three main methods for measuring non-methane total hydrocarbons using FID detectors: gas chromatography, catalytic oxidation, and low-temperature freezing pre-concentration. The principle of the catalytic oxidation method is as follows: one channel of the gas to be tested is directly passed into the FID detector to obtain the content of total hydrocarbons, and the other channel of the same gas to be tested is passed through a heated catalyst to react the hydrocarbons in the gas to be tested except methane After generating carbon dioxide and water, pass the remaining methane in the gas to be tested into the FID detector to obtain the content of methane, and then subtract the content of methane from the content of total hydrocarbons to obtain the content of to...
