Description
Technical field
The present invention relates in general to the instrument field that catalyst performance characterizes, and is specifically to provide a kind of optics of liquids detection cell with ultralow light path detected for optics of liquids.
Background technology
Optical detection is widely used in the qualitative and quantitative analysis such as material detection, structure analysis, Concentration Testing.For the detection of liquid, because the density of liquid is comparatively large, absorbance is comparatively large, cannot meet the testing requirement of fluorescence detector as infrared detector, UV-vis detector.General solution includes liquid diluting and the light path reducing optical detection.But liquid diluting can be destroyed the original state of liquid, obvious the method cannot be used for the detection of liquid in-situ, and simultaneously dilution can bring measuring error, and the problem such as troublesome poeration.Being reduced by light path is a kind of feasible mode, but for meeting the detection demand of fluorescence detector, light path generally needs to be decreased to below 1mm, but be subject to the restriction of technique, general liquid cell is difficult to meet, therefore develop a kind of structural manufacturing process simple, optics of liquids detection cell easy to use seems extremely important.
Summary of the invention
It is simple that the present invention have devised a kind of structural manufacturing process, optics of liquids detection cell easy to use.This optics of liquids detection cell adopts kapillary through O type circle, and window presses the structural approach that O type circle carries out sealing.Specifically, in the present invention, optics of liquids detection cell is made up of pond body, kapillary, O type circle, window, pad and clamping screw etc.Pool center is porose, can through the kapillary of certain external diameter, and the kapillary one end inside the body of pond penetrates in O type circle again.O type circle upper and lower side puts window, pad respectively successively, and then is screwed into clamping screw, utilizes window to compress O type circle, also compresses the kapillary inserted in O type circle, reach the object of sealing.O type circle, pad and clamping screw are hollow structure, ensure that the test light of vertical irradiation can not be blocked.When carrying out optical detection to fluid sample, the distance between two windows is the light path of liquid entering Chi Tizhong and detect, and namely light path may diminish to 0.5mm, can be used for detectable concentration so comparatively large or compare the fluid sample of thickness.
Be described in detail below in conjunction with accompanying drawing
Fig. 1 is the mounting structure schematic diagram (not containing pond body) of ultralow path liquid bulk optics detection cell of the present invention;
Fig. 2 is the Longitudinal cross section schematic of ultralow path liquid bulk optics detection cell of the present invention.
In the present invention, optics of liquids detection cell is made up of pond body 6, kapillary 2 (comprising 2-1,2-2), O type circle 1, window 3 (comprising 3-1,3-2), pad 4 (comprising 4-1,4-2) and clamping screw 5 (comprising 5-1,5-2) etc.Pond body 6 is stainless steel, also can be other materials such as rigid plastic, aluminium, copper.Respectively there is a circular hole at pond body about 6 center, kapillary 2-1 and 2-2 of certain external diameter can be each passed through, the one end of kapillary 2-1 and 2-2 inside pond body 6 penetrates in O type circle 1 respectively again, O type circle 1 can be made for soft materials such as butyronitrile, fluororubber, silica gel, and its thickness can be 0.5 ~ 10mm.O type circle 1 upper end puts window 3-1, pad 4-1 respectively successively, lower end puts window 3-2, pad 4-2 respectively successively, O type circle 1, window 3-1,3-2 conform to the endoporus aperture of pond body 6 with the external diameter of pad 4-1,4-2, just snap in pond body 6, and then be screwed into clamping screw 5-1 and 5-2 coincide with pond body 6 upper and lower side screw thread, utilize window 3-1 and 3-2 to compress O type circle 1, also compress kapillary 2-1 and 2-2 inserted in O type circle 1, reach the object of sealing.Window 3-1 and 3-2 can make for various transparent or nontransparent material, and its material and thickness can require to customize according to user, in general, can select KBr or CaF for infrared detection
2window etc.; Quartz window sheet etc. can be selected for UV detect.Pad 4-1 and 4-2 can be the material such as teflon or nylon.O type circle 1, pad 4-1,4-2, clamping screw 5-1,5-1 are hollow structure, ensure that the test light of vertical irradiation can not be blocked.Can find out, when carrying out optical detection to fluid sample, liquid enters in the space between upper and lower two window 3-1 and 3-2 by kapillary 2-1 or 2-2 inserting body 6 center, pond, as test light vertical irradiation window 3-1 and 3-2, between two windows, the distance of 3-1 and 3-2 is light path, namely light path may diminish to 0.5mm, can be used for detectable concentration so comparatively large or compare the fluid sample of thickness.
Can see, the light path of this optics of liquids detection cell is little, and structure is simple, is convenient to dismounting, and be easy to service sink body and change window, therefore this optics of liquids detection cell can be widely used in the optical detection of liquid, has higher practical value and application prospect.
