WebSolid Phase Extraction. 19 Sample Preparation. Dissolve the sample in the mobile phase or in a solvent weaker than the mobile phase. The sample volume should be kept as small as possible. 20 Column Storage. Avoid any physical stress to the column. Close on both ends to avoid dryness. Store the column well flushed with the appropriate solvent. WebSep 2, 2024 · The majority of HPLC systems are quaternary in nature, i.e. can pump from four different inlet lines. If more than one line is to be used (i.e. the method involves a gradient), then the final solution to be flushed through each line should be a solvent that is compatible with the mobile phase. For instance, if the mobile phases have high buffer ... Web2.
