Chapter 5, Problem 5.9P

Interpretation Introduction

Interpretation:

The following statements has to be explained.

1. 1. Above the detection limit approximately $\text{1\%}$ chance of falsely concluding that the sample does contain no analyte.
2. 2.  Above the detection limit approximately $\text{50\%}$ chance of concluding that the sample doesn’t contains analyte.

Concept Introduction:-

Detection limit:-

The concentration of an analyte that produces a signal which is equal to three times the standard deviation of a signal from a blank.

$\text{minimum detectable concentration}\text{=}\frac{\text{3s}}{\text{m}}$

Where,

S = Standard deviation.

m = Slope of linear calibration curve.
