Preface

This 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 13090-2006 “Determination of 666 and DDT in feed”. In addition to structural adjustments and editorial changes, the main technical changes are as follows. a) The scope of application and detection limit have been changed, and the limit of quantification has been added (see Chapter 1, Chapter 1 and Chapter 3 of the.2006 edition); b) The principles have been changed (see Chapter 4, Chapter 3 of the.2006 edition); c) The sample preparation method has been changed (see Chapter 7, Chapter 6 of the.2006 edition); d) The test steps have been changed (see Chapter 8, Chapter 7 of the.2006 edition); e) The test data processing has been changed (see Chapter 9, Chapter 8 of the.2006 edition); f) The precision requirements have been changed (see Chapter 10, Chapter 9 of the.2006 edition). This document is modified to adopt ISO 14181.2000 “Determination of organochlorine pesticide residues in animal feeding stuffs—Gas chromatography method”. This document has the following structural adjustments compared to ISO 14181.2000. ---Added Chapter 3; --- Chapter 4, Chapter 5 and Chapter 6 correspond to Chapter 3, Chapter 4 and Chapter 5 of ISO 14181.2000; --- Chapter 9 corresponds to 9.1 of ISO 14181.2000; --- Chapter 10 corresponds to 11.2 of ISO 14181.2000. The technical differences between this document and ISO 14181.2000 and their reasons are as follows. --- Changed the scope of application and clarified the types of feed (see Chapter 1, Chapter 1 of ISO 14181.2000) to match the feed Standards are coordinated to facilitate understanding and application by document users; --- Increased the detection limit and changed the quantification limit (see Chapter 1, Chapter 1 of ISO 14181.2000) to comply with the requirements of the 6-hexadecene in feed in my country. Liuhe DDT actual detection technology level, to meet the actual detection needs; --- The sample extraction method has been changed (see 8.1, 8.2, 8.3 of ISO 14181.2000) to meet the requirements of the six 6.DDT testing needs; --- The purification method adds "chromatographic column purification II method" and "concentrated sulfuric acid sulfonation method" (see 8.2, 8.4 of ISO 14182.2000) to meet the requirements of Meet the needs of detecting BHC and DDT in various feed samples in my country; --- Deleted "sample" (see Chapter 6 of ISO 14181.2000), "recovery calculation" (see 9.2 of ISO 14181.2000), "confirmation "Analysis of the quality of the product" (see Chapter 10 of ISO 14181.2000), "Inter-laboratory testing" (see 11.1 of ISO 14181.2000), "Re- "Presence" (see 11.3 of ISO 14181.2000), "Test Report" (see Chapter 12 of ISO 14181.2000), in order to comply with my country's The actual situation of detection of BHC and DDT in feed. The following editorial changes have been made to this document. --- To coordinate with the existing standard, the name of the standard is changed to "Determination of 666 and DDT in Feed"; --- To comply with the actual situation of the detection of 666 and DDT in feed in my country, the informative annex in ISO 14181.2000 is deleted.

4 Principles

According to the principle of similarity, the analyte in the sample is extracted with a mixed solution of acetone and n-hexane, and the extract is purified by solid-liquid partition chromatography. (Or use concentrated sulfuric acid to dehydrate and sulfonate the interference, remove it), the purified liquid is separated by capillary column gas chromatography, and detected by electron capture detector.
