Where y is the response ratio and x is the concentration
(ng/g).
(
2
) Calculate the concentration in a final sample dilution, by
interpolating from the standard curve: Interpolated concn.,
(ng/g) = (sample response ratio – b)/m
(
3
) Calculate the concentration in a sample, based on the
interpolated concentration:
