Hydrophilic interaction liquid chromatography (HILIC) has emerged as a promising alternative to traditional ion-pair reversed phase liquid chromatography (IP-RPLC) methods for separating oligonucleotides (ON). This work investigates the application of HILIC to the separation of ON sequence and length variants, duplexes, and single-stranded components.

The “matrix effect” is one of the sticky details that can make the use of liquid chromatography (LC) for quantitative purposes challenging, even though it is conceptually quite straightforward. In this installment of LC Troubleshooting, Dwight Stoll reviews what is being referred to during talks about “matrix effects”, and discusses some of the potential origins of the phenomenon in practice.
