Question:
The following calibration data were obtained by an instrumental method for the determination of the species X in aqueous solution:
Conc.X,CₓPPm | No. Replications N | Mean Analytical Signal, S | Standard Deviation, PPm |
0.00 | 25 | 0.031 | 0.0079 |
2.00 | 5 | 0.173 | 0.0094 |
6.00 | 5 | 0.422 | 0.0084 |
10.00 | 5 | 0.702 | 0.0084 |
14.00 | 5 | 0.956 | 0.0085 |
18.00 | 5 | 1.248 | 0.0110 |
a) Calculate the Calibration sensitivity
b) Find the analytical sensitivity at each analytic concentration
c) Find the coefficient of variation for the mean of each of the replicate sets.
d) what is the detection limit for the method?
