Reliability in Analytical Chemistry 24 SENSITIVITY vs SELECTIVITY. The use of the term “selectivity” in analytical chemistry has evolved in parallel with the development of more sensitive and discriminating methods that have a capability to identify and quantify analytes with less interference from other components, similar or dissimilar, than earlier methods were able to do. This volume, written by three distiguished experts, systematically delivers the complete and in-depth information that enables both researchers and users of square-wave voltammetry to apply this technique effectively. Research work on this reagent was first carried out by Hellmuth Fischer, originally as a purely personal interest — virtually a hobby. The sensitivity of a test can help to show how well it can classify samples that have the condition. The key difference between specificity and selectivity is that specificity is the ability to assess the exact component in a mixture, whereas selectivity is the ability to differentiate the components in a mixture from each other. Increase in gain, increases m and s by similar amount. A very important step in validation is the recovery test, performed using the addition of known amounts of analyte(s) in real samples.
