Embodiment 1

[0046] like figure 1 , figure 2 Shown, a kind of hydrogen isotope chromatographic peak data processing method, comprises the following steps:

[0047] S1, collecting hydrogen isotope chromatographic data;

[0048] S2, calculating the average value of the baseline amplitude of the hydrogen isotope chromatogram;

[0049] S3, polarity inversion processing negative peak data in hydrogen isotope chromatographic data;

[0050] S4, judging the starting point, end point and apex of the chromatographic peak;

[0051] S5, delete the noise peak data in the hydrogen isotope chromatographic data;

[0052] S6, calculating the time, peak width, peak height and peak area information of the effective peak shape.

[0053]Through the above steps, the present invention conveniently integrates the test of hydrogen isotope and the quantitative calculation of chromatogram, is convenient to realize based on the integrated hardware and software environment, and can be integrated into an online a...

Embodiment 2

[0082] like figure 1 , figure 2 As shown, as a further refinement of Embodiment 1, this embodiment provides a specific method for implementing the present invention by taking tritiated hydrogen isotopes as an example.

[0083] It includes the following steps:

[0084] 1) The output voltage of the TCD detector is collected at a certain time interval. Each data point has two elements, time and amplitude. The abscissa is time in minutes, and the ordinate is amplitude in microvolts. Each data point has a sequence number, the sequence number of the first point is 1, the sequence number of the second point is 2, and so on; the time interval is ΔT. It is agreed that the data with the smaller sequence number is the front-end data, and the data with the larger sequence number is the back-end data.

[0085] 2) Several data collected at the beginning are tritiated hydrogen isotope chromatographic baseline data (that is, partial data with smaller serial numbers), and some data are sel...

Description

technical field [0001] The invention relates to the technical field of chromatographic quantitative analysis, in particular to a method for processing hydrogen isotope chromatographic peak data. Background technique [0002] As a mature technology, gas chromatography technology is widely used in various fields, but the commercial conventional chromatography and microchromatography that are really applied to hydrogen isotopes have poor results, and major chromatography companies have not carried out extensive technical development in this direction. and market development. It is often necessary to purchase conventional chromatographs and then modify them. Only through a large number of experiments and method establishment can they be applicable to the test scenarios of hydrogen isotopes. However, the quantitative calculation methods of chromatography are often integrated in its dedicated supporting software, and calculation parameters cannot be adjusted. Such a technical sol...
