Hello,did anybody heard before the method to determin LOD via calibration curve? How to do this?
By vijay on Tuesday, July 27, 2004 - 05:08 am:
from the linearity curve find out residual standard deviation and slope.
Now one can derive
LOD = 3.3*residual stdandard deviation / slope.
LOQ = 10*residual stdandard deviation / slope.
FOR finding out resdiual standard deviation one can use MS-EXCEL application. for the selected two sets of variables follow =styex(Y1:Yn, X1:Xn).
i hope this may give some details about your query.
