3 Terms and Definitions

Terms and definitions GB/T 4946 and GB/T 9977 defined apply to this document. Principle 4 Using a gas chromatograph equipped with a thermal conductivity detector by gas chromatography column to separate sample components, and through integrator or microprocessor Write down the value of chromatographic peak area of \u200b\u200beach component. Under the same operating conditions, analyze the content of the standard gas of known composition using the external standard method, the measured Obtained samples with standard gas chromatographic peak area of \u200b\u200bchromatographic peak area compared to calculate the content of each component.

5 Apparatus and materials

5.1 standard gas Standard gas analysis may be required by the national standard of two substances or GB/T 5274 preparation. Component standard gas should be in uniform gaseous. For the sample component concentration of not more than 5% of the standard gas concentration should not be a large component To 10%, should not be less than 50% of the concentration of the respective components in the sample. For the sample component concentrations greater than 5%, the concentration of the standard gas composition Not less than 50% of the corresponding component concentration of the sample, the sample should not be greater than 50% of the concentration of the respective components. After checking the syringe can be used with pure gas formulated as a standard component in the sample gas standard as close as possible. When formulated, should be maintained Permit its accuracy. 5.2 Gas Chromatograph With dual thermal conductivity detector, gas chromatograph Double Air Road. 5.3 Working conditions typical chromatogram Typical chromatographic operating conditions are shown in Table 1. ......
