[求助] 河流沉积物有机物测定方法检出限怎么做?

论文投稿时提的意见:
L135-137 S/N is not feasible for most complex matrices such as river sediments. MDLs should be based on the deviation from the lowest standard on the calibration curve using spiked samples, or similar.
而我论文中原本是这样写的:
the method detection limits (MDLs) of PAHs were determined as the concentration of analyses in a sample that gives rise to a peak with a signal-to-noise ratio (S/N) of 3.
当时是空白基3倍线性噪比作为method detection limits。
