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 heatable optics of liquids detection cell of low 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, generally use infrared detector, UV-vis detector and Composition distribution etc.For the detection of liquid, because the density of liquid is comparatively large, absorbance is comparatively large, cannot meet the detection demand of fluorescence detector as infrared detector, UV-vis detector.General method of operating includes liquid diluting and the light path reducing optical detection.Sample to be determined is poured in planchet by the former, is then positioned in the detection light path of detecting device and detects.This detection mode can destroy the original state of liquid, such as temperature and pressure, and simultaneously dilution can bring measuring error, and the problem such as troublesome poeration, therefore cannot be used for the detection of liquid in-situ.And for used in-situ liquid optical detection tank, owing to being subject to the restriction of technique, general liquid cell light path is all comparatively large, the testing requirement of detecting device cannot be met; Do not possess the function of heating in addition, after high-temp liquid introduces optical cell, there will be the condensation of liquid, so can change the original state of liquid yet, therefore affect the in situ detection of liquid yet yet.
For this reason, the applicant proposes the application for a patent for invention of " ultralow path liquid bulk optics detection cell " and " can heating liquid optical detection tank " in January, 2014, achieve the ultralow liquid detecting pond of light path respectively and there is the liquid detecting pond of heating function, on this basis, present applicant has proposed a kind of structural manufacturing process simple, low light path easy to use can heating liquid optical detection tank, low light path and heating function are combined, the liquid guaranteeing to enter optical detection tank keeps original state, realizes the optical characterisation of original position.
Summary of the invention
It is simple that the present invention have devised a kind of structural manufacturing process, low light path heat insulation liquid optical detection tank easy to use.This low light path heat insulation liquid optical detection tank adopts kapillary through O type circle, window presses the structural approach that O type circle carries out sealing and realizes low light path, adopt the pond body of particular design to realize heating optics of liquids detection cell simultaneously, ensure that the liquid of flowing in it is not lowered the temperature, realize the in situ detection of liquid.Specifically, in the present invention, low light path heat insulation liquid optical detection tank is made up of pond body, O type circle, kapillary, window, pad, pad clamping screw, heating ring and heating ring clamping screw etc.There is circular hole at body left and right sides center, pond, 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.Pad and clamping screw are hollow structure, ensure that the test light of vertical irradiation can not be blocked.Distance between two windows is the light path entering the liquid that Chi Tizhong detects, and namely light path may diminish to 0.5mm.The upper and lower side of pond body has long and narrow duct simultaneously, heats pond body for putting into heating ring, makes the liquid of inflow pond body keep temperature, ensures the detection of liquid in-situ.
Be described in detail below in conjunction with accompanying drawing
Fig. 1 is the Longitudinal cross section schematic of the pond body of low light path heat insulation liquid optical detection tank of the present invention
Fig. 2 is the mounting structure schematic diagram (not containing pond body) of low light path heat insulation liquid optical detection tank of the present invention;
Fig. 3 is the Longitudinal cross section schematic of mounted low light path heat insulation liquid optical detection tank of the present invention.
In the present invention, optics of liquids detection cell is made up of pond body 1, O type circle 2, kapillary 8 (comprising 8-1,8-2), window 3 (comprising 3-1,3-2), pad 4 (comprising 4-1,4-2), pad clamping screw 6 (comprising 6-1,6-2), heating ring 5 (comprising 5-1,5-2) and heating ring clamping screw 7 (comprising 7-1,7-2) etc.Pond body 1 is stainless steel, also can be other materials such as rigid plastic, aluminium, copper.There is circular hole 12 at pond body 1 left and right sides center, kapillary 8-1 and 8-2 of certain external diameter can be each passed through, the one end of kapillary 8-1 and 8-2 inside pond body 1 penetrates in O type circle 2 respectively again, and O type circle 2 can be made for soft materials such as butyronitrile, fluororubber, silica gel, and its thickness can be 0.5 ~ 10mm.Window 3-1 is put respectively successively in O type circle 2 upper end, pad 4-1, window 3-2 is put respectively successively in lower end, pad 4-2, O type circle 2, window 3-1, 3-2 and pad 4-1, the external diameter of 4-2 conforms to the endoporus aperture of pond body 1, just snap in pond body 1, two ends, Chi Tinei center about 11 are female thread structure (not shown), with there is externally threaded pad clamping screw 6-1 and 6-2 mate, by tightening clamping screw 6-1 and 6-2 coincide with pond body 1 upper and lower side screw thread, window 3-1 and 3-2 is utilized to compress O type circle 2, also kapillary 8-1 and 8-2 inserted in O type circle 2 is compressed, 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
