Boron is a nutritional component that facilitates cell division and strengthens cell walls. In the Fertilizers Regulation Act (Law No. 127 of 1950), there is a specification for the minimum contents of nutritional components to ensure the quality of a fertilizer and the labeling of the contents according to the solubility is mandated. ZA3000 series instruments employ the polarized Zeeman method for BKG corrections even for the flame method. The accurate BKG corrections and a very stable baseline allow the analysis of boron at low concentrations with a high temperature burner. When citrate soluble boron in a fertilizer certified reference material was analyzed, the analysis value corresponding to the certified value was obtained.
