Hilic approaches
WebDec 2, 2015 · This paper describes a HILIC approach for carbohydrate analysis using an organofunctional amide stationary phase that has been developed to overcome many of the separation challenges that are … WebThe charge state of the column itself can also be affected. For example, in a Raptor HILIC-Si column, the bare silica has a pKa between 3.8 and 4.5, so the mobile phase pH changes the charge of the silica surface, making it neutral in very acidic conditions and ionized (negatively charged) as the pH begins to approach 3.8 and above.

WebT cell function is determined by transcriptional networks that are regulated by epigenetic programming via posttranslational modifications (PTMs) to histone proteins and DNA. Bottom-up mass spectrometry (MS) can identify histone PTMs, whereas intact protein analysis by MS can detect species missed by bottom-up approaches. We used a novel … WebThe diluted samples were analyzed by two chromatography methods: Reverse phase and hydrophilic interaction liquid chromatography (HILIC) with a data dependent MS2 acquisition strategy to enable detection and confirmation of markers of honey adulteration.
WebThe HILIC-UPLC method has a potential advantage over reversed-phase methods, as the elution times of lipid classes are predictable, so a reduced list of transitions can be used at a particular time, reducing the duty cycle of the mass spectrometer.
