Mass spectral measurements were made on 10 replicate low concentration Pb-EDTA samples: 190.5 190.5 , 146.2 146.2 , 160.9 160.9 , 175.9 175.9 , 144.9 144.9 , 214.3 214.3 , 165.9 165.9 , 170.5 170.5 , 159.9 159.9 , and 177.5 177.5 counts. Ten measurements of a blank had a mean measurement of 44.3 44.3 counts. A sample containing 3.00 3.00 μM Pb-EDTA gave a measurement of 1777 1777 counts. Estimate the signal and detection limit for Pb-EDTA.
