Zusammenfassung

This test method covers the testing of the spectral bandwidth and wavelength accuracy of fluorescence spectrometers that use a monochromator for emission wavelength selection and photomultiplier tube detection. The method can be applied to instruments that use multi-element detectors, such as diode arrays, but results must be interpreted carefully. Atomic lines between 250 nm and 1000 nm are used in the method. The difference between the apparent wavelength and the known wavelength for a series of atomic emission lines is used as a test for wavelength accuracy. The apparent width of some of these lines is used as a test for spectral bandwidth.
