Description
Technical field
The utility model relates to a kind of automatic polarimeter, is specifically related to the polarization tube sample adding device on a kind of automatic polarimeter.
Background technology
Automatic polarimeter is the instrument measuring material optical activity.By the mensuration of optical activity, concentration, content and the purity etc. of determining material can be analyzed.
Same sample, under different temperatures, optical activity is different.Because the optical activity of sample is relevant with sample temperature, so in high precision and high speed are measured, Quality control temperature is the key ensureing to measure.
Carry out on the polarimeter with Peltier function of temperature control to use temperature control polarization tube being measured as example, see Fig. 1, the application of sample of current domestic many temperature control polarization tubes 100 needs the end cap 110 at two ends to open.This mode can affect speed and the accuracy of measurement.The stress that the piezoid 120 at temperature control polarization tube two ends can produce, the reflection of stress is exactly be embodied in have in optical activity.After adding blank solvent and carrying out school zero, end cap 110 need be opened and carry out application of sample, again end cap 110 be tightened after application of sample terminates, certainly different when the stress of now piezoid 120 generation at two ends and school zero, will measuring error be caused like this; And application of sample needs the Peltier temperature control chip of temperature control polarization tube 100 from instrument to take off, at the outside application of sample of instrument, external temperature and Peltier temperature control temperature inconsistent, temperature control is again needed when remeasuring, take the many time, have impact on efficiency, reduce measuring speed and precision.
Utility model content
The utility model in order to solve the problem that the measuring speed existed in above-mentioned measurement mechanism is low and precision is low, thus provides a kind of polarization tube sample adding device improving the practical convenient of measuring accuracy and speed.

Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the cut-open view of existing polarization tube;
The cut-open view of the polarization tube that Fig. 2 provides for the utility model;
Fig. 3 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 2 and Fig. 3, the polarization tube sample adding device on the automatic polarimeter that the utility model provides, it is made up of polarization tube 200, nesting tube 300, sample feeding pipe 400 and injector 500.
Polarization tube 200, it is for settling sample, and it is the same with existing polarization tube 100, and two ends are also respectively equipped with end cap 210 and piezoid 220, and it is specifically placed in sample cell, also can be arranged in instrument temperature controlling groove according to the actual requirements.
Be provided with nesting tube 300 in one end of polarization tube 200, nesting tube 300 is communicated with polarization tube 200 inside, is provided with sample feeding pipe 400 at the other end of polarization tube 200.
Nesting tube 300, it is that specifically can arrange a waste liquid cup 600, waste liquid can be drained in waste liquid cup 600 by nesting tube 300 for being discharged by the waste liquid in polarization tube 200.
Injector 500, it is connected with sample feeding pipe 400, and sample or blank solvent or air can enter in polarization tube 200 by sample feeding pipe 400 by it.
For the ease of controlling feed rate, sample feeding pipe 400 is also provided with a regulator 410.
Here is specific works principle of the present utility model:
6ml blank solvent is got to use injector 500, all be pressed in polarization tube 200 by sample feeding pipe 400 by solvent, feed rate can regulate by difference regulator 410 per sample, and waste liquid drains in waste liquid cup 600 by nesting tube 300, after solvent is all pressed into, regulator 410 is adjusted to closed condition.
Instrument carries out school zero, after school zero is terminated, open regulator 410, use injector 500 by 6ml air press-in polarization tube 200, now in polarization tube 200, solution is all discharged by nesting tube 300, injector 500 is used to get 6ml sample, by sample feeding pipe 400, sample is all pressed in polarization tube 200, feed rate can per sample in difference sample feeding pipe regulator 410 regulate, waste liquid drains into waste liquid cup 600 by nesting tube 300, after sample is all pressed into, regulator 410 is adjusted to closed condition.
By above-mentioned enforcement, polarization tube 200 is placed on all the time in instrument temperature controlling groove in measuring process, the piezoid 210 at two ends need not be taken off and loads onto, the optical activity that the piezoid 210 at two ends produces due to stress when school zero by error concealment, can not measuring error be produced, improve measuring accuracy;
Because polarization tube 200 is placed in instrument temperature controlling groove all the time, temperature in temperature control temperature claimed range, does not need temperature control again during measurement all the time, has saved the many time, has improve measuring speed.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
