摘要
采用乙酰甲胺磷纯度标准物质为原料,以丙酮为溶剂,制备了浓度为1.00 mg/mL的乙酰甲胺磷丙酮溶液标准物质,用液相色谱法和气相色谱法进行了确认,A类标准不确定度为0.009%,B类标准不确定度包括标准物质制备、原料纯度、不均匀性和不稳定性引入的不确定度,其量值分别为0.43%,0.10%,0.87%和0.24%,合成不确定度为0.03 mg/mL(k=2),乙酰甲胺磷丙酮溶液标准物质的浓度为(1.00±0.03)mg/mL。
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.
