Low concentrations of warfarin near the detection limit gave the dimensionless instrument readings: 195.5, 166.9, 152.5, 164.5, 209.5, 150.3, 213.3, 191.9, 124.9, and 195.7. Ten blanks had a mean reading of 40.7. The slope of the calibration curve is 3.09 x 10° M-¹. Estimate the signal and concentration detection limits and the lower limit of quantitation for warfarin.
