Mass spectral measurements were made on 10 replicate low concentration Cu-EDTA samples: 173.7 , 130.0 , 146.3 , 161.3 , 130.3 , 199.7 , 151.3 , 155.9 , 145.3 , and 162.9 counts. Ten measurements of a blank had a mean measurement of 25.1 counts. A sample containing 3.00 μM Cu-EDTA gave a measurement of 1679 counts. Estimate the signal and detection limit for Cu-EDTA.
