A method for measuring the triamino-s-triazine content in various fertilizer mixes has been developed and collaboratively studied. Samples are dissolved in deionized water and analyzed using liquid chromatographic separation on a RP-18 LiChrosorb column. Collaborators analyzed 5 sets of blind duplicates, comparing peak heights to an external standard to quantitate the triamino-s-triazine content. Coefficients of variation ranged from 0.8 to 2.2%. The method has been adopted official first action.

UI	MeSH Term	Description	Entries
D007202	Indicators and Reagents	Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.
