Please define what the “selectivity” for a given analytical method refers to? (b) How does the selectivity of a method vary as the calibration sensitivity of potential interfering species vary?
Homework Answers
Selectivity refers to the extent to which a method can determine particular analytes in mixtures or matrices without interferences from other components.

2. Many spectroscopic techniques require an optimal compromise between selectivity and sensitivity. Define these two analytical figures of merit and explain why the compromise is necessary (Hint: Think about how the spectrometer slit width would affect the Raman analysis of a calcium ascorbate sample with impurities with peaks that overlap with those of calcium ascorbate).

How would you demonstrate accuracy of an analytical method? a)Run a sample with a known concentration of analyte and see if the concentration you determine matched the known value b)Determine LOD for the method – it must be below 100 ng/ml for analyte dissolved in reagent (ultrapure) water c)Use least-squares method to determine the slope of the calibration curve (in the slope is less than 10, the method is inaccurate)

A new analytical method to detect pollutants in water is being tested. This new method of chemical analysis is important because, if adopted, it could be used to detect three different contaminates - organic pollutants, volatile solvents, and chlorinated compounds - instead of having to use a single test for each pollutant. The makers of the test claim that it can detect high levels of organic pollutants with 99.3% accuracy, volatile solvents with 99.97% accuracy, and chlorinated compounds with 89.8%...
