ABSTRACT:
When analysing saccharides by HPAEC, the eluate from the column is typically analysed using a amperometric detector. According to the invention, amperometric detection is coupled with ultraviolet detection, with both methods being applied to the eluate. Thus the invention provides a method for analysing the eluate from a liquid chromatography column, wherein the eluate is analysed by both (a) amperometric detection and (b) ultraviolet detection. The information content derivable from using both sorts of detection advantageously exceeds that derivable from either of the two detection methods alone.
