Abstract When analyzing extracts of pharmaceutical preparations, the chromatographer may place some of the base fats or oils onto the reverse phase analytical column with each injection. This is not a problem if they are washed free from the column periodically. If not cleaned off the column, column efficiency and selectivity can be lost forever. A simple procedure is described for washing columns.
