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).
