[Analysis of Acidic Tar Dyes in High-Protein Foods: Achievement of Improved Recoveries and Shortened Operation Time by Loading Sample Extract onto Polyamide Columns at pH 8.5]
{{output}}
The recoveries of xanthene dyes in the analysis of acidic tar-dyes in high-protein foods were improved by loading them onto polyamide columns at pH 8.5, instead of using the conventional pH 3-4 solution. The experimental scale was reduced to approximately half... ...
