Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 30431-2013 "Laboratory Gas Chromatograph".
Compared with GB/T 30431-2013, the main technical changes of this standard are as follows.
---Modified the abbreviation FID for hydrogen flame ionization detector (see Chapter 3, Chapter 3 of the.2013 edition);
--- Modify the normal working conditions of the instrument (see 4.1, 4.1 in.2013 version);
--- Modify the technical requirements and safety test methods of contact current in safety requirements (see 4.3, 5.3, 4.3.1 and 5.3 of.2013 edition);
--- Increasing the technical requirements and methods of carrier gas flow stability (see 4.5, 5.5);
--- Modify the temperature gradient to temperature uniformity, modify the relevant detection methods (see 4.6.4, 5.6.3,.2013 version 4.5.3, 5.5.2);
---Modified the range of capillary split ratio (see 4.8, 5.8.3, 4.7, 5.7.1.2 in.2013 edition);
--- Deleted the recorder [see 4.12b.2013, 5.6];
--- Increased the technical requirements and methods of high and low temperature environment adaptability and power supply voltage adaptability (see 4.12, 4.13, 5.12, 5.13);
--- Deleted the collision test during the transportation and storage of the instrument (see 4.11 and 5.11 of the.2013 edition);
--- Modified the content of the complete set of the instrument (see 4.15, 4.12 of the.2013 edition);
--- Added illustration of the reading method of baseline noise and baseline drift (see Figure 5.7.2.1 Figure 2 and Figure 3);
---Modified the ECD and NPD test reference conditions and added test reference conditions for different samples TCD and FID (see
5.7.1 Table 2,.2013 version 5.6.1 Table 2);
--- Increased TCD detection limit technical indicators and test methods (see Table 4.7, 5.7.2.2);
--- Increased TCD linear range of the sample benzene-toluene solution (or n-hexadecane-isooctane solution) (see 5.7);
--- Modified the test conditions and methods of the linear range (see 5.7, 5.6 of the.2013 edition);
--- Modified the FPD (sulfur) detection limit formula [see 5.7.5.2
