Description
Technical field
The utility model relates to a kind of rear deriving device, particularly relates to a kind of online photochemistry post-column derivation device.
Background technology
Some chemical substances, such as aflatoxin, cannot detect very low amount with fluorescence detector at all, and what adopt at present is that fluorescence detector just can reach lower detectability.But aflatoxin has divided multiple, normal detection have aflatoxin B1, G1, B2, G2, wherein AFB 2, G2 can produce fluorescent material, but B1, G1 fluorescent characteristic runs into the easy cancellation of mobile phase, cause can't detect or content very low, only have the derivative enhancing in same various countries fluorescent characteristic, just can detect.Conventional method derives with chemical reagent before post, or use electrochemical derivatization after post.Column front derivation wants manual operations, poor repeatability, takies manpower, and detection efficiency is very low.After post, the reagent of electrochemical derivatization is now with the current, and compound concentration changes, and can affect the repeatability peak of not same date.And these two kinds of methods all will use derivative reagent, cause potential injury to human body.And electrochemical derivatization device needs to prepare the instruments such as independent infusion pump after post, add detection deployment cost, resulting cost is very high, can not meet the requirement of people.
Utility model content
The purpose of this utility model is to provide a kind of online photochemistry post-column derivation device, solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of online photochemistry post-column derivation device, is characterized in that, comprise lamp bracket, lamp house, reflector, bracing frame, uviol lamp, netting twine, support frame as described above is the bracing frame of stainless steel, the bottom of bracing frame is provided with reflector, described reflector has the reflective feature of one side, and reflector is provided with louvre, and louvre is used for connection and the heat radiation of derivative spool, lamp bracket is provided with ultraviolet and derives lamp and starter, lamp bracket is placed on inside lamp house.
Further, the shape of support frame as described above is U-shaped, is convenient to that light is built-in to be prevented from ultraviolet from leaking outside bringing injury to user.
Further, described netting twine is PTFE netting twine or FAP netting twine, and netting twine has withstand voltage and effect that is heat affecting, and light transmission is fabulous, ensures derivative effect efficiently.
Advantageous Effects of the present utility model is: the post-column derivation being mainly used in liquid chromatographic system, thus the online photochemical derivatization of Realization analysis sample and online high-sensitivity detection, structure is simple, easy to assembly, favorable reproducibility, analysis speed are fast, can long-time continuous carry out, without the need to any organic reagent, environmental protection, life-span is long, can not bring impact to whole liquid phase systems.
