Abstract

This document specifies a method for determining the total content (solvent extractable) of melamine in chemicals for the leather tanning industry.

This method requires the use of liquid chromatography (LC) with a triple quadrupole mass spectrometer (MS/MS), an ultraviolet (UV) detector, or diode array detector (DAD) to identify and quantify the melamine.
