Liquid chromatographic determination of triamino-s-triazine in fertilizer mixes: collaborative study.
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.
