WebHILIC SPE can also purify labeled glycans after derivatization from excess reagents, which can potentially interfere with downstream chromatography, reduce the lifetime of a column, and thereby impair method robustness. WebDec 26, 2008 · The ZIC-HILIC SPE efficiently removed sources of interference present in the supernatant after protein precipitation of plasma proteins. The main advantage of the ZIC-HILIC SPE sample preparation step was that it allowed load and elution conditions to be optimised to extract only peramivir and minimize co-extraction of lipophilic phospholipids.

WebHILIC is a particularly useful separation mode for polar organic compounds that are poorly retained by reversed phase. Retention of these polar compounds using reversed phase methods is often difficult because of co-elutions with the solvent front or elutions within the chromatographic region where ion suppression is the greatest.
