Abstract
This invention employs solid phase extraction media and column methods to apply external and internal standards and compounds. Analytical standard or compounds including PFAS are adsorbed to a solid phase extraction media and are stored indefinitely. The standards or compounds remain stable on the solid phase extraction media without decomposing. The standards or compounds may be removed from the solid phase extraction media with an elution solvent or reagent.
