Lcms hilic
WebHILIC separation is an alternative that permits sensitive MS detection and without the use of ion-pair reagents. Nucleotides are the building blocks of nucleic acids. They comprise a nitrogenous base, a sugar, and a phosphate group making them highly polar and ionic. This causes a challenge for typical reversed phase chromatography (RPC). Web17 mei 2024 · LC-MS is suitable for the analysis of polar and non-polar compounds, as well as thermolabile molecules. These compounds can range from low molecular mass analytes with m/z values < 1000 Da, to very high molecular mass proteins with m/z …

WebHILIC or Hydrophilic Interaction Liquid Chromatography is a high-performance liquid chromatographic (HPLC) technique for separation of polar and hydrophilic compounds. Originally the separation technique was called "Hydrophilic-Interaction Chromatography", and occasionally the expression "Aqueous Normal Phase" has also been used.
