Fertilizers - Determination of urease inhibitor N-(n-butyl)thiophosphoric triamide (NBPT) using high-performance liquid chromatography (HPLC); English version of DIN EN 15688:2008-11
This document specifies a method for the quantitative determination of the urease inhibitor N-(n-
butyl)thiophosphoric triamide (NBPT) content in water-soluble matrices, i.e. urea based fertilizers using high
performance liquid chromatography (HPLC).
NOTE Pure NBPT reference material is required as a standard for the quantitative calibration.
