Standard Test Method for Limit of Detection of Fluorescence of Quinine Sulfate
|Publication Date:||30 March 1984|
|ICS Code (Organic nitrogen compounds):||71.080.30|
1.1 This test method employs the signal-to-noise ratio theory to determine the sensitivity of a fluorescence measuring system in testing for the limit of detection (LOD) of quinine sulfate. The results obtained with quinine sulfate are suitable for specifying instrument performance on samples having excitation and fluorescence bands wider than 10 nm.
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.
1.2 This test method has been applied to fluorescence-measuri
1.3 The practical lower limit of this test method is 1 ng of quinine sulfate per mL (one part per billion; 1 ppb).
1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
