Foreword
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents"
Drafting.
This document replaces GB/T 23961-2009 "Gas Chromatography Method for Determination of Low-Carbon Fatty Amine Content" and is consistent with GB/T 23961-2009
In addition to structural adjustments and editorial changes, the main technical changes are as follows.
---The minimum detection content has been added to the range (see Chapter 1);
---Changed the chromatographic analysis conditions (see Chapter 8, 3.5 of the.2009 edition);
---The calculation formula has been changed (see Chapter 10, 3.7 of the.2009 edition);
---Added relative correction factor reference value list (see Appendix A).

1 Scope
This document describes the gas chromatography method for the determination of main content and organic impurity content in 15 low-carbon fatty amine products.
This document applies to monoethylamine, diethylamine, triethylamine, monoisopropylamine, diisopropylamine, mono-n-propylamine, and di-n-propylamine produced by the alcohol ammoniation process.
Amine, tri-n-propylamine, mono-n-butylamine, di-n-butylamine, tri-n-butylamine, mono-isobutylamine, diisobutylamine, mono-sec-butylamine, di-sec-butylamine, and ketone amination process
Determination of the main content and organic impurity content of the prepared monoisopropylamine, diisopropylamine, mono-sec-butylamine and di-sec-butylamine. The minimum detectable content is
0.01% (mass fraction).

3 Terms and definitions
There are no terms or definitions to be defined in this document.
4 Method summary
Under the selected working conditions, the sample is vaporized in the vaporization chamber and passes through the capillary chromatographic column, so that each component in the sample is effectively separated.
Isolation was detected using a hydrogen flame ionization detector and quantified using the calibrated area normalization method.
5 Reagents and materials
5.1 Hydrogen. the volume fraction is not less than 99.99%, dried and purified by silica gel and molecular sieves.
5.2 Nitrogen. the volume fraction is not less than 99.99%, dried and purified by silica gel and molecular sieves.
5.3 Air. oil-free, dried and purified by silica gel and molecular sieves.
5.4 Standard reagents. used to prepare calibration mixed solutions. See Table A.1 in Appendix A for the reagents used and specifications.
