Final answer:
To calculate the signal detection limit, concentration detection limit, and lower limit of quantitation for EDTA, we would need the standard deviation of the blank measurements in addition to the mean blank reading and the slope of the calibration curve. Without this information, exact values cannot be provided.
Step-by-step explanation:
To estimate the signal detection limit (SDL) for EDTA, you usually start from the mean blank reading and the standard deviation of the blank measurements. Although the standard deviation is not provided, if we had it, we'd typically calculate the SDL as the mean of the blanks plus three times the standard deviation of the blanks. In this case, you only provided the mean of the blanks which is 45.0.
The concentration detection limit (CDL) can then be calculated using the slope of the calibration curve. If SDL were known, CDL = SDL / (slope of the calibration curve). Here, the slope is given as 1.75 x 109 M-1.
The lower limit of quantitation (LLOQ) is typically calculated as the mean of the blanks plus ten times the standard deviation of the blanks, divided by the slope of the calibration curve. This is the lowest concentration at which the analyte can not only be reliably detected but also quantified with suitable precision and accuracy.
Without the standard deviation of the blank measurements, it's not possible to provide exact values for SDL, CDL, and LLOQ. Had we had all the necessary data, we could use the provided slope and the measurements to calculate the actual limits.
