| Abstract: | Acephate in acetone reference material with 1.00 mg/mL was prepared by using purity reference material.The concentration was assessed by gas chromatography – flame ionization detector(FID),high-performance liquid chromatography–diode array detection(HPLC–DAD),respectively.The uncertainty of certified value was estimated including the uncertainty of the measurement repeatability(0.009%),solution preparation(0.43%),purity reference material(0.10%),unhomogeneity(0.87%) and unstability(0.24%).The expanded uncertainty was 0.03 mg/mL(k=2).The concentration value for acephate was(1.00±0.03) mg/mL. |
