InertSphere FA-1, for USP/EP/JP, Povidone, Formic Acid Test

Povidone (polyvinylpyrrolidone, PVP) is used in the pharmaceutical industry as a synthetic polymer vehicle for dispersing and suspending drugs. It additionally acts as a disintegrant and tablet binder. The revision to the harmonized standard for Povidone has been approved and Formic Acid in Povidone is now required to be measured. The new InertSphere FA-1 columns are inspected using a standard solution of formic acid prior to shipment, which is the most appropriate column to be used in this new testing.
