Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 30430-2013 "Standard column for gas chromatograph test", compared with GB/T 30430-2013, except
The main technical changes outside the editorial changes are as follows.
--- Removed the relevant content of "large-diameter capillary column" (see 3.1, 4.1, 4.2, 5.2.2, 8.1.3 of the.2013 edition);
--- Removed FPD and FPD (P), FPD (S) related content (see 3.3, 5.1.2, 6.1.1.2, 6.1.1.3,.2013,
6.1.2.4, A.1.2 in Appendix A, and A.1.3 in Appendix A);
--- Increased the terminology and formula, index and test method for separation (see 3.1.2, 5.1.2, 5.2.2, 5.3, 6.1.2.2, Appendix A)
A.1, Appendix A, A.2);
--- Increased the standard column fixed liquid film thickness parameters, modify the column length and its error parameters (see 4.2, 4.2 edition of 4.2);
--- Deleted the relevant content of "effective number of meters per meter" (see 5.1.2, 5.2.2, 6.1.2.2.3 of the.2013 edition);
--- Increased pressure gauge for test equipment (see 6.1.1.1);
---Modified "carrier gas flow rate" as "carrier gas flow rate" (see 6.1.1.3, Appendix A, A.1,.2013 edition, 6.1.1.3, Appendix A)
A.1.1);
---Modified test procedures (see 6.1.2.3, 6.1.2.4, 6.1.2.3, 6.1.2.4 of the.2013 edition);
--- Revised the schematic diagram of the gas resistance measurement of the column and added a statement of the test method (see 6.1.2.4, 6.1.2.3 of the.2013 edition);
--- Modified the mass concentration of naphthalene (see 6.2.1.2, 6.2.1.2 of the.2013 edition);
--- Revised the "standard column can withstand 400 ° C high temperature" provisions (see 8.1.1,.2013 version 8.1.1);
--- Modified the packed column performance test chromatogram and capillary column performance test chromatogram, removed the solvent peak mark (see Appendix A)
A.1 in Appendix A.1, Appendix A, A.1.1 in Appendix A of.2013 edition, and A.2 in Appendix A).

(1)
In the formula.
T ---tailing factor;
W0.05h --- 0.05h peak height at the peak height, in seconds (s);
D1 --- The distance from the peak of the peak to the vertical line, the distance from the intersection of the W0.05h peak width line to the front edge of the peak, in seconds (s).
