Low concentrations of EDTA near the detection limit gave the following dimensionless instrument readings: 175, 104, 164, 193, 131, 189, 155, 133, 151, and 176. Ten blanks had a mean reading of 50.0. The slope of the calibration curve is 1.75 x 10^-9 M^-1.
1. Estimate the signal detection limit for EDTA. (with correct sig figs)
2. What is the concentration detection limit? (with correct sig figs)
3. What is the lower limit of quantification? (with correct sig figs)
