Low concentration replicate samples of Pb-EDTA gave the following counts in a mass spectral measurement: 188.3, 145.9, 159.7, 174.7, 143.7, 213.1, 164.7, 169.3, 158.7, 176.3. Ten measurements of a blank had a mean of 27.3 counts. A sample containing 1.00 ìM Pb-EDTA gave 1877 counts. Estimate the signal and concentration detection limits for Pb-EDTA.
