Title:
METHOD FOR QUANTIFYING 3,6-ANHYDRO-L-GALACTOSE USING HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY AND DIFFERENTIAL REFRACTOMETRIC DETECTOR
Document Type and Number:
WIPO Patent Application WO/2019/013489
Kind Code:
A3
Abstract:
The present invention relates to a method for quantifying 3,6-anhydro-L-galactose using high-performance liquid chromatography and a differential refractometric detector, whereby L-AHG and D-galactose, which are saccharification products of agarose or agar, can be independently quantified by controlling the separation conditions of the high-performance liquid chromatography/differential refractometric detector, even though the two materials are difficult to separate due to having similar molecular weights and structures.
