Abstract
The present disclosure is directed to methods of separating one or more non-modified oligosaccharide(s) with degree of polymerization 6 or higher from a sample using a hydrophilic interaction liquid chromatography (HILIC) column connected to a liquid chromatography system that includes coated flow paths. The methods disclosed herein requires, inter alia, a liquid chromatography system, wherein at least one component of the LC system includes a fluid-contacting alkylsilyl coating. When implementing a standard HILIC method, the methods of the present technology can be used to decrease the analyte loss and/or carry-over of the separation leading to improved analysis.
