the IS normalized MF was calculated by dividing the MF of the analyte by the MF of the IS. The stability tests were conducted on the bench-top for 6 h, 3 freeze/thaw cycles, post-preparative for 8 days in the autosampler (set at 10 ?C) and in a freezer set at ?30 ?C for 1 month. Analyte concentrations were calculated using a 1/x2 weighted linear least-square regres-sion analysis of the standard curve. 这几句啥意思啊 |

IS(Internal Standard) 内标 MF (matrix factor)基质效应因子 IS normalized MF:内标归一化基质效应因子 the IS normalized MF was calculated by dividing the MF of the analyte by the MF of the IS. 待测物与内标的MF的比值为内标归一化基质效应因子 The stability tests were conducted on the bench-top for 6 h, 3 freeze/thaw cycles, post-preparative for 8 days in the autosampler (set at 10 ?C) and in a freezer set at ?30 ?C for 1 month. 稳定性试验: 室温稳定性:试验台上放置6h 冻融稳定性:3个冻融循环 处理后样品稳定性:自动进样器内放置8天(某温度)、冰箱内放置1个月(某温度)。 Analyte concentrations were calculated using a 1/x2 weighted linear least-square regres-sion analysis of the standard curve. 待测物浓度由标准曲线计算,线性拟合:最小二乘法,加权因子1/x^2 。 |
