You are asked to do quality control and quality assurance during the determination of lead concentration in a city’s tap water using ICP-AES. Plotting ICP -AES signal as a function of lead concentration (in ppb) gave you a linear regression equation of y = 1.97x + 1.50 with an R^2=0.99. The instrumental response (signal) had a standard deviation of 0.75. What is the limit of quantitation in terms of lead concentration (ppb) of this instrumental method?
