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

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）。
