PFA – Chemical Resistance
PFA is an excellent choice for sample introduction systems because it resists the most aggressive organic and inorganic chemicals and solvents over the broadest temperature range, including:
- strong mineral acids (including HF)
- inorganic bases
- inorganic oxidizing agents
- salt solutions
- aldehydes
- chlorocarbons
- organic acids
- anhydrides
- aromatics
- alcohols
- ketones
- esters
- fluorocarbons
PFA is only attacked by certain halogenated complexes containing fluorine, molten sodium and potassium. PFA, therefore, is resistant to any liquid sample that can be analyzed by ICP-OES and ICP-MS.
