ICS 37.040.20 CCSG80 National Standards of the People's Republic of China Replaces GB/T 25248-2010 Infrared Absorbing Cyanide Dyes for 830nm Digital Imaging Materials Determination of content by high performance liquid chromatography Published on 2026-01-28 Implemented on August 1, 2026 State Administration for Market Regulation The State Administration for Standardization issued a statement.

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 25248-2010 "Determination of Cyanide Content in 830nm Digital Plate Making Materials by Infrared Absorption Spectrometry". Compared with GB/T 25248-2010, the main technical changes in "Chromatography" are as follows, apart from structural adjustments and editorial modifications. a) The reagent "dioxane" was changed to "potassium dihydrogen phosphate" (see 7.2, 6.2 in the.2010 edition); b) The specifications for the water used have been changed (see 7.3, 6.3 in the.2010 edition); c) The 10mL volumetric flask has been removed (see 7.3 in the.2010 edition); d) The instrument "pipette" was changed to "pipette" and its capacity was changed (see 8.4, 7.4 in the.2010 version); e) The pore size of the filter membrane used was changed (see 8.5, 7.5 in the.2010 edition); f) Columns of the specified brand were removed (see 8.1 in the.2010 edition); g) The mobile phase composition was changed (see 9.2, 8.2 in the.2010 edition); h) The detection wavelength was changed (see 9.5, 8.5 in the.2010 edition); i) Added relevant content on chromatograms (see 9.6); j) The sample solution preparation method and the specifications for the filter membrane used before entering the column have been changed (see 10.1, 9.1 in the.2010 edition).
