The solvents used in HILIC methods are similar to those employed in reversed-phase LC (e.g., water, methanol, and acetonitrile) and vola-tile buffers and modifiers may also be used. Because HILIC stationary phases are polar, the technique is well suited for the analysis WebMar 28, 2016 · Follow Storage of HILIC columns with buffer is recommended to decrease equilibration time. Storing a column with buffer in the mobile phase is typically not recommended for a number of reasons, most have little to do with sorbent stability. Buffers can precipitate if the organic concentration is too high but water will evaporate first.
