Mass spectral measurements were made on 10 replicate low concentration Pb-EDTA samples: 152.7, 114.6, 128.1, 143.1, 112.1, 181.5, 133.1, 137.7, 127.1, and 144.7 counts. Ten measurements of a blank had a mean measurement of 27.7 counts. A sample containing 2.00 µM Pb-EDTA gave a measurement of 1601 counts. Estimate the signal and concentration detection limits for Pb-EDTA. signal detection limit: counts concentration detection limit: µM
