Embodiment
As shown in Figure 1 and Figure 2, a kind of liquid absorbance measuring of this city embodiment device, comprises main body 1, light source 21, sensor 31, measuring vessel 4; Wherein light source 21 is single color LED or laser tube, is no matter to adopt single color LED or laser tube, and the light launched of light source 21 is all demarcate by the intensity after measuring vessel that water or reagent blank is housed, is designated as Ia; Measuring vessel 4 is the ampoule bottle of 8 ~ 15mm for diameter, encapsulates reagent in advance in ampoule bottle.Ampoule bottle why is selected to be that have special machine perfusion reagent, sealed ampoule bottle bottleneck, with low cost, simple, consistance is good because ampoule bottle uses in a large number in pharmaceuticals industry.Why being arranged between 8 ~ 15mm by the diameter of ampoule bottle, is because if ampoule bottle diameter is less than 8mm, then the light launched of light source 21 is fewer by the amount of the liquid absorption of institute's splendid attire in ampoule bottle, is unfavorable for measuring.And if the diameter of ampoule bottle is greater than 15mm, then the light that light source 21 is launched can be more by the liquid absorption of splendid attire in ampoule bottle, and that is the light that senses completely of sensor 31 is more weak, so the real absorbance time error calculating liquid in ampoule bottle is larger.Through experimental verification when the diameter of ampoule bottle is between 8 ~ 15mm, be beneficial to the parameter measurement of liquid in ampoule bottle most.
Above main body 1, have a groove 11, this groove 11, for loading ampoule bottle, has a through hole 12 in the side of main body 1, and the axes intersect of the axis of this through hole 12 and groove 11;
In the left and right sides of main body 1, the two ends of through hole 12 have left groove, right groove; Wherein light source 21, sensor 31 are arranged in left groove, right groove respectively in opposite directions; Light source can pass through hole 12 directive sensor 31.
In order to realize the location of light source and sensor more efficiently; Liquid absorbance measuring device also comprise respectively with left groove, the left plunger 2 of the corresponding threaded engagement of right groove, right plunger 3, sensor 31 is embedded in the left end of right plunger 3, and now light source 21, sensor 31 are arranged at the two ends of through hole 12 respectively in opposite directions; The light that light source 21 is launched, through through hole 12 directive sensor 31, decreases light loss, improves measuring accuracy.
Convenience in addition in order to dismantle, is also respectively arranged with slip-resistant texture at the outside surface of left plunger 2, right plunger 3.
The use procedure of a kind of liquid absorbance (Abs) measurement mechanism of the utility model is as follows:
1. first, the bottleneck of ampoule bottle is broken, quantitative test substance is added ampoule bottle, and shake up to make the complete Homogeneous phase mixing of the reagent in test substance and ampoule bottle;
2. then ampoule bottle obtained for step 1 is inserted in the groove 11 of body upper surface;
3. then open light source 21, the light that light source 21 is launched also finally is beaten on sensor 31 by through hole 12, ampoule bottle, and the light received responded to by sensor 31, and the intensity that record receives light is I
b; Just can show that in ampoule bottle, the Abs of liquid is-log (I thus
b/ I
a).
Further, the utility model measurements and calculations can also be used to go out the concentration of liquid in ampoule bottle; Concrete steps are as follows:
A) first, choose a coloured ampoule bottle as calibration thing, and the Abs predicting this coloured ampoule bottle is equivalent to certain concentration known is X
1the Abs of liquid.Such as: certain selected coloured ampoule bottle, its Abs is equivalent to the Abs that concentration is the solution of the something of 1mol/L;
B) Abs then this coloured ampoule bottle being measured this coloured ampoule bottle according to step 2 ~ 3 of the use procedure > of above-mentioned < liquid A bs measurement mechanism is I
1;
C) then the ampoule bottle that testing liquid is housed is measured according to step 2 ~ 3 of the use procedure > of above-mentioned < liquid A bs measurement mechanism the AbsI that liquid surveyed by this band
2;
D) the concentration X of this testing liquid is then calculated according to the following equation
2:
X
2＝(X
1*I
2)/I
1
The measuring method of this kind of strength of fluid is owing to adopting coloured ampoule bottle as calibration thing, compared to traditional employing concentration known standard substance as calibration thing, eliminate the preservation problem of the standard substance of concentration known, greatly reduce complicacy and the cost of test procedure, there is larger practical value.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
