ASTM E579 – Standard Test Method for Limit of Detection of Fluorescence of Quinine Sulfate in Solution
1.1 This test method employs the signal-to-noise ratio to determine the sensitivity of a fluorescence measuring system in testing for the limit of detection (LOD) of quinine sulfate dihydrate in solution. The results obtained with quinine sulfate dihydrate in solution are suitable for specifying instrument performance on samples having excitation and fluorescence bands wider than 10 nm at or near room temperature.
1.1.1 This test method is not intended to be used as (1) a rigorous test of performance of instrumentation, or (2), to intercompare the quantitative performance of instruments of different design. Intercomparison of the LOD between instruments is commonly expressed as the ratio of the water Raman peak intensity to the root-mean-square (rms) noise as measured on a fluorometer using an excitation wavelength of 350 nm This test method uses the excitation and emission peak wavelengths for quinine sulfate dihydrate in solution, which are approximately 350 nm and 450 nm, respectively.
