In the first GC columns, gas chromatography phases were simply coated onto the column. This was mostly the case with packed columns, but also the same with the very first capillary columns. Injecting water onto these phases dissolved the phase and caused the phase to elute from the columns.
Hydrophilic interaction liquid chromatography (HILIC) is a chromatographic mode used mainly for the separation of polar compounds that are too hydrophilic to be retained in a reversed phase column.

Peaks in your chromatogram not attributed to the sample injected are commonly referred to as ghost peaks. Several problems can be the cause of ghost peaks manifesting, including: Late Continue Reading
