Hilic separation
WebHILIC 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% … WebIt uses designed stationary phases instead of bare alumina or silica particles. HILIC fills a need in analytical separations and is used for the separation of very polar molecules like …

Did you know?
WebBecause the separation mechanism in HILIC methods involves the adsorption of a water layer on the particle surface, it is very important to completely reestablish or “reset” this water layer in between injections to ensure retention time reproducibility. We recommend equilibration with a minimum of 10 column volumes starting when the ...
WebHILIC is the most straightforward, versatile and robust separation technique for polar and hydrophilic compounds, compared to the above options. Dedicated, bonded stationary phases with high stability and reproducibility are since a few years available for HILIC … WebApr 2, 2024 · HILIC and RPLC are complementary separation methods . HILIC is separating lipids based on their headgroup polarity leading to coelution of all lipid molecular species of a corresponding subclass and its ISTD. RPLC is separating lipids mainly based on hydrophobicity of their fatty acid chains leading to separation of lipid molecular species …
WebThermo Fisher Scientific WebHILIC phases can be grouped into neutral polar or ionic surfaces. Table 1 shows the different structures of stationary phases that are applicable to HILIC-mode separation. …
WebLike Normal Phase Chromatography, HILIC uses a polar stationary phase and a non-polar yet water-miscible mobile phase. It uses designed stationary phases instead of bare alumina or silica particles. HILIC fills a need in analytical separations and is used for the separation of very polar molecules like acids, bases, and zwitterions.
