Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents"
Drafting.
This document replaces GB/T 30433-2013 "Standard Chromatographic Columns for Liquid Chromatograph Testing". Compared with GB/T 30433-2013,
In addition to structural adjustments and editorial changes, the main technical changes are as follows.
---Modified the term "theoretical board number" and moved the original standard formula (1) to 6.2.2 (see 3.1, 6.2.2, 3.1 in the.2013 edition);
---Modified the term "tailing factor" and moved the original standard formula (2) to 6.2.3 (see 3.2, 6.2.3, 3.2 in the.2013 edition);
---Clarify that the column efficiency is expressed by the number of naphthalene peak theoretical plates (see 5.2, 4.2 in the.2013 edition);
---It is clear that the tailing factor is expressed as a naphthalene peak, and 1,4-dihydroxyanthraquinone has been deleted (see 5.3, 4.3 in the.2013 edition);
---Modified the test equipment, changed the "10μL (or 20μL) syringe" in the original standard to "sampler" and added "volume flask" (see
6.1.1, 5.1.2 of the.2013 edition);
--- Deleted "It is necessary to operate in a fume hood when preparing the test solution" (see 5.1.3 of the.2013 edition);
---Modified reagents, deleted 1,4-dihydroxyanthraquinone, nitrobenzene, sodium dihydrogen phosphate dihydrate, sodium hydroxide, fluorene and other items (see 6.1.2.1,
5.1.3.1 of the.2013 version);
---Modified the standard solution, and modified the test column performance and tailing factor with fluorene and 1,4-dihydroxyanthraquinone to test column performance and
The tailing factor is prepared with naphthalene solution (see 6.1.2.2, 5.1.3.2 of the.2013 edition);
---The buffer salt preparation has been deleted (see 5.1.3.3 of the.2013 edition);
--- Deleted the 1,4-dihydroxyanthraquinone method (see 5.2.3.2 in the.2013 edition);
---Modified the standard column pressure drop test method, and described the test method in more detail (see 6.2.4, 5.2.4 of the.2013 edition).
