The following methods for detection of melamine/cyanuric acid were developed bythe Food and Drug Administration's (FDA's) Office of Regulatory Affairs.
GC-MS Screen for the Presence of Melamine, Ammeline, Ammelide and Cyanuric Acid (Version 2.1), May 16, 2007
GC-MS Method for Screening and Confirmation of Melamine and Related Analogs (Version 2), May 7, 2007
The FDA Field laboratories are using LC-MS/MS methods that are capable of determining melamine and cyanuric acid at levels of 0.25 ppm in powdered infant formula and other dairy-containing food products or ingredients. These and a GC/MS method for melamine and its analogues are:
*Melamine Methodology
*Determination of Melamine and Cyanuric Acid Residues in Infant Formula using LC-MS/MS
*Interim Method for Determination of Melamine and Cyanuric Acid Residues in Foods using LC-MS/MS
*GC/MS method for melamine and analogues
