Hilic-uplc法

WebHILIC Overview. HILIC can be described as a variation of reversed phase chromatography performed using a polar stationary phase. The mobile phase employed is highly organic in nature (> 60-70% solvent, typically acetonitrile) containing a small percentage of aqueous solvent/buffer or other polar solvent. The water in the mobile phase forms an ... WebHILIC has been referenced as one of possible approaches. However, there is a lack of experimental evidence in scientific literature so far. Methodology: Matrix effects were evaluated using spiked serum samples after SPE and protein precipitation prior to UHPLC-ESI-MS/MS. Chromatography was performed in both HILIC and reversed-phase mode. The …
