Abstract

The present disclosure relates to a method of reducing degradation of sample components in a liquid chromatography system. The method utilizes a masked metal frit to prevent or reduce metal surfaces from becoming catalytically active. The masked metal frit is a metal based frit that includes a coating on its exterior surfaces to mask or prevent contact between the organic solvents (and/or any analyte or other related solvent) and the underlying metal. The coating is a vapor deposited inorganic-organic hybrid coating, such as a vapor deposited C2 coating.
