Individual monosaccharides can be linked in a variety of different combinations to form complex glycoconjugates. In contrast to DNA and proteins, glycoconjugate synthesis does not follow any template but is the consequence of the concerted action of various enzymes such as transferases and glycosidases . Thus, tools for glycoconjugate sequencing need to differentiate individual monosaccharide identity, linkage and anomericity to investigate and understand glycoconjugate function. In this chapter we provide a concise overview on the most commonly used and robust tools to separate and characterise glycoconjugate isomers.
