Fluorescence detector (FLD) is a commonly used detector in high-pressure liquid chromatography. When the chromatographic fraction is irradiated with ultraviolet light, it can be detected when the sample components have fluorescence properties.
High selectivity, only responsive to fluorescent substances; The sensitivity is also high, with a minimum detection limit of 10-12ug/ml, suitable for trace analysis of polycyclic aromatic hydrocarbons and various fluorescent substances. It can also be used to detect substances that do not emit fluorescence but can emit fluorescence after chemical reactions. In phenolic analysis, most phenols do not emit fluorescence, so they are first processed to become fluorescent substances before analysis.
