ICS 65.120 CCSB46 National Standards of People's Republic of China Replacing GB/T 17814-2011 Butylated hydroxyanisole, dibutyl hydroxytoluene, tert-butylhydroquinone, ethoxyquinoline and gallic acid Determination of Propyl Ester Posted on 2022-12-30 2023-07-01 implementation State Administration for Market Regulation Released by the National Standardization Management Committee forewordThis document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules for Standardization Documents" drafting. This document replaces GB/T 17814-2011 "Butylated hydroxyanisole, dibutyl hydroxytoluene, ethoxyquin and propyl gallate in feed Determination of Esters", compared with GB/T 17814-2011, except for structural adjustment and editorial changes, the main technical changes are as follows. a) Extend the scope of application of high performance liquid chromatography to concentrate supplements and feed ingredients (see Chapter 1, Chapter 1 of the.2011 edition); b) The determination of butyl hydroxyanisole, dibutyl hydroxytoluene, ethoxyquinoline and propyl gallate by high performance liquid chromatography has been changed. Limit of detection and limit of quantitation (see Chapter 1 and Appendix A, Chapter 1 of the.2011 edition), adding high-performance liquid chromatography for the determination of terbutin Detection limit and determination of butylated hydroxyanisole, dibutyl hydroxytoluene and ethoxyquinoline by hydroquinone and gas chromatography Quantity limits (see Chapter 1 and Appendix A); c) Added high-performance liquid chromatography for the determination of tert-butylhydroquinone (see Chapter 4); d) Added the preparation of oil sample solution (see 4.5.1.1); e) Deleted the packed column method in gas chromatography (see 4.2.4.1.2 of the.2011 edition).
