Description
Technical Field
The invention relates to the technical field of photochemical derivatization equipment, in particular to a photochemical derivatization device.
Background
When detecting an analyte by liquid chromatography, if the analyte is a compound having fluorescence, the detection can be performed by using a fluorescence detector. By analyzing each constituent component having fluorescence in the target, it is possible to distinguish between the components by the difference in their fluorescence. However, liquid chromatography requires that an analysis target be injected into a column under the drive of a liquid mobile phase for analysis. Therefore, the analysis target inevitably comes into contact with the aqueous phase. Generally, most types of analyte targets that exhibit fluorescence do not significantly adversely affect their fluorescence when contacted with water. However, for some types of analyte targets (e.g., aflatoxins B1 and G1), the fluorescence of the analyte targets decreases or even loses upon contact with water, i.e., quenching of the fluorescence occurs. However, if the fluorescence of the analyte is low or lost, it cannot be directly detected by the fluorescence detector.
For this purpose, the fluorescence can be enhanced or restored by derivatization and then detected. At present, commonly used derivatization methods mainly include trifluoroacetic acid derivatization, iodine derivatization, and the like. However, the method has complicated operation steps and poor test repeatability; the photochemical derivatization device can conveniently carry out derivatization reaction on a target object to improve the fluorescence of the target object, but the internal structure of the existing photochemical derivatization device is too simple, and only one ultraviolet lamp tube fixed in a reaction coil blocks the illumination of some parts due to the blocking of a bracket, and simultaneously causes the illumination intensity of the inner ring part and the outer ring part of the derivatization pipeline to be different; in addition, the existing device is lack of a heating and heat-insulating assembly to cause unstable environmental temperature of the derivatization reaction, so that the inhomogeneous reaction effect of the derivatization reaction at each position in the derivatization pipeline is poor, and the later-stage detection result is influenced finally.
