Accuracy in sampling analysis could be determined by analyzing a reference material of known concentration (or value), or by re-analyzing a sample to which a material of known concentration has been added (recovery method). For example, if T is the total concentration of a water quality parameter in a spiked sample, U is the concentration of the same parameter in the unspiked sample, and A is the amount of the parameter added to the hitherto unspiked sample, the percent recovery R is calculated as [R equals (T minus U) divided by A, multiplied by 100]. 2, record 1, English, - spiked%20sample
