Identifying oligonucleotide impurities and metabolites with high-resolution mass spectrometry

Stephen Lock, Marketing and Market Development, SCIEX, Marlborough, US (steve.lock1704@gmail.com)

In this presentation learn how a QTOF system can be used for high resolution quantitation of oligonucleotides providing the performance of a triple quadrupole. Learn how the improvements in sensitivity in MS/MS scanning and quantitation together with new software solutions are enabling users to easily identify impurities and improve the characterization of oligonucleotides and finally understand how LCMSMS can be used with ion pairing or HILIC chromatography to detect oligonucleotides in biological extracts.
