Fluorescence SpectroMeter

Fluorescence spectrometers analyze material composition by exciting samples to produce fluorescence and detecting the fluorescence wavelength and intensity. They are used to detect fluorescent substances in coatings and inks, plastic additives, paper fluorescent brighteners, etc., enabling qualitative and quantitative analysis of material composition.
Selection
When selecting, consider the matching of the detection element range with the sample. The power of the X-ray tube affects the detection limits, the type of detector relates to accuracy, and the sample chamber size should accommodate different shapes. The operating software needs to be intuitive and user-friendly, while maintenance costs and manufacturer technical support should be practically evaluated.
