Description
· High Performance Liquid Chromatography (HPLC) Method for Analysis of Trimellitic anhydride .
Trimellitic anhydride is a trifunctional, highly reactive aromatic anhydride with the chemical formula C 9 H 4 O 5 . It is used as a curing agent for epoxy and other resins; in vinyl plasticizers, paints, coatings, dyes, pigments and a wide variety of other manufactured products.
Trimellitic anhydride can be retained in HPLC with a Newcrom BH mixed-mode column using a mobile phase of acetonitrile (ACN) and water and Sulfuric Acid (H2SO4) buffer allowing the use of a UV detector at 210 nm.
