Rapid analysis of shale gas components by laser Raman spectroscopy1 ScopeThis standard specifies the analytical method for determining the main chemical composition of shale gas by laser Raman spectroscopy. This standard applies to the analysis of shale gas components in the range shown in Table 1, and it also applies to the determination of one or several components in shale gas. Note. The range of shale gas component concentrations that can be measured by laser Raman spectroscopy can be wider, but the reliability of the measurement results is not within the scope of this standard.2 Normative referencesThe following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this document. For undated references, the latest version (including all amendments) applies to this document. GB/T 5274.1 Preparation of mixed gas for gas analysis and calibration Part 1.Preparation of first-level mixed gas by weighing method SY/T 7433 Natural gas composition analysis by laser Raman spectroscopy3 Principles of the methodLaser Raman shale gas composition analysis should follow the method principle specified in SY/T 7433.As shown in Figure 1, the laser emits laser to the gas. In the sample cell, the laser collides with the shale gas component and emits Raman scattered light, which is processed by the detection module and converted into a Raman signal, which is then transmitted to the signal The measurement result is output after processing and user interface. Since the Raman scattering spectra of different components are specific, by detecting different molecules in the sample The specific frequency and intensity of the spectrum are compared with the frequency and intensity of the Raman spectrum of a known standard gas to obtain the composition and content of the sample. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 39540-2020_English be delivered?Answer: Upon your order, we will start to translate GB/T 39540-2020_English as soon as possible, and keep you informed of the progress.
