METHOD FOR MEASURING FORMALDEHYDE IN SOLUTIONS CONTAINING CERTAIN FORMALDEHYDE-RELEASING BIOCIDES

摘要

A method for measuring formaldehyde in an aqueous solution of an oxazolidine or hexahydro-1,3,5-triazine biocide; said method comprising separating an amino alcohol produced by hydrolysis of said biocide via mixed mode chromatography and detecting said amino alcohol using a charged aerosol detector or an evaporative light scattering detector.
