1) The filler retains the title compound
Solid phase extraction operation generally has four steps:
Activate - remove impurities from the column and create a solvent environment.
Loading - the sample is dissolved with a certain solvent, transferred into the column and the components remain on the column.
Leaching - to maximize the removal of disturbances.
Elution - elutes the test substance with a small volume of solvent and collects it.

2) Filler retains impurities

Solid phase extraction operation generally has three steps:
Activate - remove impurities from the column and create a solvent environment.
Loading - the sample is transferred to the column, where most of the target compound will flow out of the sample base and the impurities remain on the column. So this step is to start collecting.
Elution - The components are rinsed and collected in small volumes of solvent. Consolidate the collection solution.
This situation is mostly used in food or pesticide residue analysis to remove the pigment.
