Disclosed herein are embodiments of methods for oligonucleotide analysis using a novel solid-phase extraction and hydrophilic-interaction liquid chromatography. The unique polar-based retention methods provided herein provide a high-recovery extraction. The methods improve assay reliability and reproducibility and reach picomolar sensitivity with the demonstrably beneficial accurate mass platform. Also disclosed herein are systems and computer program products for performing these methods.

Methods and systems for hydrophilic-phase extraction

Methods of LC-MS analysis of oligonucleotides free of ion-pairing reagents are disclosed herein. Historically, ion-pairing reagents have been used for acceptable extraction and chromatography prior to mass spectral analysis. The disclosure herein presents methods free of ion-pairing reagents at each stage, from extraction through the LC-MS endpoint. Also disclosed herein are systems for performing these methods.
