The Azomethine H by Dinâmica, available at LojaLab, is a chromogenic reagent used for colorimetric determination of boron. In a buffered medium under controlled conditions, it reacts with boron species to form a yellow complex that can be measured by spectrophotometry. Wavelength, color-development time, buffer composition and sample treatment vary among methods. Calibration standards, reagent blanks, interference control and an analytical curve are therefore essential.
