Why is an Analytical Guard Column Necessary?

Various reagents are used in the mobile phase of HPLC, in which some insoluble or impure substances are mixed. Most insoluble can be removed by filtering the mobile phase through a frit or membrane filter, but very fine particles will pass through the filter. In addition, after the mobile phase is prepared, there is a possibility that insoluble or impure substances may fall in from the air, a container, a human body, or the like. These insoluble and impurities may contaminate the column, cause clogging, or adversely affect analysis, depending on the purpose of analysis. At this time, it can be prevented by installing an analytical guard column in front of the chromatographic column, which can protect the chromatographic column.
