Low concentrations of methylmercury near the detection limit gave the dimensionless instrument readings: 208.1 , 176.5 , 165.1 , 177.1 , 222.1 , 162.9 , 225.9 , 204.5 , 137.5 , and 208.3 . Ten blanks had a mean reading of 41.9 . The slope of the calibration curve is 1.45 × 10 9 M − 1 . Estimate the signal and concentration detection limits and the lower limit of quantitation for methylmercury.
