Deleterious Effects of Formic Acid without Salt Additives on the HILIC Analysis of Basic Compounds

LCGC International spoke with Daniel Meston and Dwight Stoll from Gustavus Adolphus College in St. Peter, Minnesota, USA, about a project they worked on with Todd Maloney from Eli Lilly in Indianapolis, Indiana, USA, to investigate the optimal performance conditions of antisense oligonucleotides (ASOs) when using hydrophilic interaction liquid chromatography (HILIC).

A new review article provides an overview of the use of two-dimensional liquid chromatography (2D-LC) for the quantitative analysis of natural products.

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.

Paris-Saclay University scientists used hydrophilic interaction liquid chromatography (HILIC) coupled to electrospray ionization mass spectrometry (ESI-MS) and inductively coupled plasma mass spectrometry (ICP-MS) to assess thorium’s interaction with peptides.

New methods have been developed to determine polar emerging contaminants with hydrophilic interaction liquid chromatography (HILIC) techniques.
