Chapter 5.1, Problem 1TY

Interpretation Introduction

Interpretation:

The $\%$ recovery if the spike sample gave a concentration of $\text{15}\text{.3μg/L}$ has to be calculated.

Concept Introduction:

Spike is also called as fortification, is better known as the amount of analyte added to a sample to test whether the response to the spike is the equal as that predictable from a calibration curve.

Definition of spike recovery percentage is the difference between concentrations of spiked sample and unspiked samples by concentration added.

$\text{\%}\text{recovery}\text{=}\frac{{\text{C}}_{\text{spiked sample}}{\text{- C}}_{\text{unspiked sample}}}{{\text{C}}_{\text{added}}}\text{×100}$
