Description
Technical field
The utility model relates to a kind of tintmeter, belongs to the chemical analysis instrument technical field.
Background technology
The tintmeter of Measurement and analysis liquid commonly used in the chemical analysis field is based on the absorption photometry principle substantially at present, and the law of this principle (lambert-law of Beer) mathematical formulae is A=log (I
0/ I)=and Kbc, in the formula: A-absorbance, I
0-incident intensity, I-transmitted intensity, K-characteristic constant, b are liquid layer thickness (or light path), c-solution concentration.Can be found out that by formula when A one timing, b is big more, then c is more little, that is to say, increases liquid layer thickness (light path) b, can detect lower material concentration; And when c one timing, b is big more, and then A is big more, that is to say, increases liquid layer thickness (light path) b, can improve sensitivity for analysis.
For example, existing water sample automatic analyzer tintmeter commonly used is (also can referring to all Chinese patent 200720043444.9 accompanying drawings 1,2 openly formerly of the utility model applicant) as shown in Figure 1, tintmeter is arranged in the reactor both sides of being made by clear glass, and light source is accepted by the optical receiving set of reactor opposite side after reactor one side emission light passes reactor; Because reactor diameter fixedly is difficult to enlarge, therefore the sensitivity of this tintmeter is not high.For this reason, existing water sample automatic analyzer has developed two kinds of flow cell formula tintmeters, as Fig. 2, shown in Figure 3.Fig. 2 is U font flow cell (Hellma colorimetric pool) tintmeter, and Fig. 3 is a zigzag flow cell tintmeter, the be placed in flow cell both sides of these two kinds of tintmeters of light source and optical receiving set, the reactant liquor of extracting out from the reactor fluid passage in the flow cell of flowing through.It is bigger that the light path of these two kinds of tintmeter flow cells can be made, but adhere to micro-bubble very easily at random at random in the fluid passage in the flow cell, thereby make incident light that rambling scattering take place, and has a strong impact on the measurement of absorption photometric.For the bubble in the fluid passage in the flow cell, at present majority is that obvious this method not only needs extra degassing equipment, and has brought many inconvenience to practical operation to the liquid processing that outgases; In addition liquid is carried out pressurized treatments, suppress the generation of bubble, but this high pressure processing method requires the high pressure resistant and good seal of flow cell, not only increase the cost of tintmeter, and failure rate height, maintenance are big by high pressure; In addition by strengthening the fluid passage diameter and reducing the unpolarized light beam diameter, though can reduce the diffuse transmission influence of bubble, can not stop the incident scattering of light fully, but also bring the fluid passage dead volume big incident light, raffinate is detained many, and flushing consumes problems such as a large amount of reagent.
The utility model content
The technical problems to be solved in the utility model is: propose a kind of optical length, thereby have the fluid analysis tintmeter that high analyte sensitivity also can detect the lower concentration reactant liquor.
The technical solution of the utility model is: a kind of fluid analysis tintmeter, comprise the support that to be located at liquid-transparent runner both sides, be placed in the light source and the optical receiving set that is placed at least one side of support of support one side, at least one side of described support is mounted with at least one catoptron, and the light that described light source sends arrives optical receiving set through mirror reflects.
Like this, when the utility model fluid analysis tintmeter uses, because the light that light source sends arrives optical receiving set through mirror reflects, therefore the light direct projection of comparing existing fluid analysis tintmeter arrives optical receiving set, light path can be multiplied, according to aforementioned lambert-law of Beer as can be known, the sensitivity for analysis of the utility model tintmeter after light path significantly increases can significantly improve, and can detect the reactant liquor of lower concentration; And then can improve precision to liquid absorbance and concentration determination.
