I would encourage the author's to revisit the LOQ calculation as the signal is the height of the peak after background subtraction. While the calculation is correct, how do the authors define the standard deviation of the background since it was removed? Was error propagation performed in this case? The data in Fig 7 does not show the background, which would help convince the reader. Please be rigorous in the important LOQ estimate. 我做的是電化學(xué)分析方向,在做曲線(xiàn)的過(guò)程中由于電容背景較大,導(dǎo)致DPV曲線(xiàn)基線(xiàn)不是平的,所以我將曲線(xiàn)的DPV曲線(xiàn)減去了空白的DPV曲線(xiàn),就是扣除了背景,但是在計(jì)算檢出限和定量限時(shí),審稿人問(wèn)了這樣一個(gè)問(wèn)題,說(shuō)我既然把背景扣除了我怎么得到的空白信號(hào)的標(biāo)準(zhǔn)偏差,同樣如果我用一個(gè)空白DPV再扣除背景的話(huà)會(huì)不會(huì)又進(jìn)行了誤差傳播。 確實(shí)不知道怎么修改怎么回復(fù)了,希望能得到大家的幫助,不甚感謝。! |
