Analysis of oligonucleotides using an ion-pairing-free reversed-phase method with TOF LC/MS

The most common method for the analysis of synthetic oligonucleotides is ion-pairing reversed-phase (IPRP) however, it is costly, environmentally harmful, and requires dedicated instrumentation. Explore an alternative method that uses time-of-flight liquid chromatography/mass spectrometry (TOF LC/MS) and a reversed-phase (RP) chromatographic method which enables accurate and repeatable analysis of diverse oligonucleotides without the use of ion-pairing reagents.
