Fenbutatin Oxide ANALYSIS
Product analysis by potentiometric non-aqueous titrimetry (CIPAC Handbook, 1988, D, 77). Residues determined by glc with ECD or FPD of suitable derivative (Anal. Methods Pestic. Plant Growth Regul., 1978, 10, 139; Methodensammlung Rückstandsanal. Pflanzenschutzmitteln, 1987, S24; M. Sano et al., J. Assoc. Off. Anal. Chem., 1979. 62, 764). Details available from BASF.
