Abstract
The utility model relates to a double-wave long fluorescence analysis lamp, which is composed of a dark box, an observation cover, a lamp tube rack, etc. The observation cover is positioned at the middle position of the top part of the dark box, and the lamp tube rack is positioned at the rear of the top part of the dark box is provided with a front door and a side door. The bottom surface of the lamp tube rack is provided with a long-wave ultraviolet lamp tube and a short-wave ultraviolet lamp tube side by side. The outer wall of the short-wave ultraviolet lamp tube is provided with an iodine-starch light filter, or the periphery of the short-wave ultraviolet lamp tube is provided with an iodine-starch filter plate. The utility model has the advantages of little parasitic light interference, high analysis sensitivity, high accuracy, no mildew of light filter (filter plate), etc.
Description
The utility model relates to a kind of analytical instrument, a kind ofly utilizes ultraviolet ray excited fluorescence to send the analytical instrument that fluorescence carries out the analyzing and testing material composition.
The fluorescence analysis lamp is a kind of analytical instrument commonly used.Whether its ultimate principle is, utilizes ultraviolet lamp tube to send ultraviolet laser fluorescence molecule generation fluorescence, exist to detect fluorescence.General often combine with thin layer chromatography (TLC), promptly earlier with unknown sample after thin-layer chromatography separates, place the fluorescence analysis lamp under observation again or make film.Because the excitation wavelength difference of various fluorescence molecules, the need that have excite with short wave ultraviolet light (254nm), and the need that have excite with long wave ultraviolet light (366nm).There is following shortcoming in this present quasi-instrument: the one, and the wavelength of shortwave ultraviolet lamp tube is impure, when sending the 254nm ultraviolet light, also send the light of other wavelength, comprise visible light, cause the background light intensity excessive like this, fluorescence is not obvious, impact analysis sensitivity and accuracy.The 2nd, optical filter or filter coating are mouldy easily, make that ultraviolet ray is obstructed, light weakens, and also reduce sensitivity for analysis.In addition, existing do not have camera bellows with quasi-instrument, needs to carry out under dark situation operation inconvenience when observing fluorescence.
The purpose of this utility model be to provide a kind of with camera bellows, its ultraviolet wavelength purity height, no veiling glare disturbs and filtering apparatus can be not mouldy double wave length fluorescent analyze lamp.
For achieving the above object, the utility model is equipped with the fluorescent tube of two kinds of wavelength on tube rack, and fluorescent tube is placed rear, camera bellows top, is provided with at the camera bellows crown center and observes cover.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is an overall construction drawing of the present utility model;
Fig. 2 is the structural drawing of tube rack of the present utility model.
With reference to Fig. 1, the utility model is made up of camera bellows (100), observation cover (200) and tube rack (300) three parts.Observe the centre position, top (103) that cover (200) is positioned at camera bellows (100); Tube rack (300) is positioned at camera bellows (100) rear, top, and tube rack (300) bottom surface becomes 30～45 with the camera bellows bottom surface.
Be provided with camera bellows door (101) in the front of camera bellows (100), be used to place sample; Also be provided with side door (102) in camera bellows (100) side, use for record.
With reference to Fig. 2, the bottom surface of tube rack (300) is equipped with long wave (366nm) ultraviolet lamp tube (305,307) and shortwave (254nm) ultraviolet lamp tube (306) side by side; Scribble the iodine-starch filter coating at shortwave ultraviolet lamp tube outer wall, or on shortwave ultraviolet lamp tube peripheral equipment the iodine-starch optical filter.
Side or top at tube rack (300) also are provided with long wave switch (301), short wave switch (302), long wave pilot lamp (303), shortwave pilot lamp (304) etc.The operating circuit of fluorescent tube adopts traditional inductance ballast circuit, and ballast resistor and starter are installed in the tube rack (300).
Because the utility model is provided with camera bellows and is added with filter coating (sheet) at the shortwave ultraviolet lamp tube, thereby do not have veiling glare and disturb, improved sensitivity and the accuracy analyzed, this filter coating filter effect is good and can be not mouldy, has improved the practical value of this instrument greatly.
Claims (2)
1, a kind of double wave length fluorescent is analyzed lamp, it is characterized in that being made up of camera bellows (100), observation cover (200) and tube rack (300) three parts; Observe the centre position that cover (200) is positioned at camera bellows top (103), tube rack (200) is positioned at camera bellows (100) rear, top; The front of camera bellows (100) is provided with camera bellows door (101), is provided with side door (102) in the side; The bottom of tube rack (200) is equipped with long-wave ultra violet lamp pipe (305,307) and shortwave ultraviolet lamp tube (306) side by side; Scribble the iodine-starch filter coating or iodine-starch optical filter on shortwave ultraviolet lamp tube peripheral equipment at shortwave ultraviolet lamp tube outer wall.
2, double wave length fluorescent according to claim 1 is analyzed lamp, it is characterized in that tube rack (300) bottom surface becomes 30～45 with camera bellows (100) bottom surface.
