Basic dataStandard ID: GB/T 23325-2009 (GB/T23325-2009)Description (Translated English): Textiles -- Determination of surfactant -- Linear alkylbenzene sulfonates Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: W04 Classification of International Standard: 59.080.01 Word Count Estimation: 8,832 Date of Issue: 2009-03-19 Date of Implementation: 2010-01-01 Quoted Standard: GB/T 6682 Regulation (derived from): National Standard Approval Announcement 2009 No.3 (Total No.143) Issuing agency(ies): General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, Standardization Administration of the People's Republic of China Summary: This standard specifies the use of liquid chromatography-tandem mass spectrometry (LC-MS/MS) determination of textile products in ten carbon, eleven carbon, twelve carbon, thirteen carbon, fourteen carbon and other five linear alkyl benzene sulfonate Methods salt (LAS) residues. NOTE: LAS refers to the structure R-C6H4-SO3-(wherein R is a straight chain alkyl group) series of alkyl benzene sulphonate. Common to ten carbon linear alkyl benzene sulphonate (C10), eleven carbon (C11), twelve carbon (C12), thirteen carbon (C13), tetradecene (C14) linear alkylbenzene sulfonic acid, etc. sodium (see Appendix A). This standard applies to all types of textile products.
