Abstract
The utility model discloses a portable laser raman spectrometer liquid sample measurement positioning device, relating to a laser raman spectrometer. The portable laser raman spectrometer liquid sample measurement positioning device is provided with a liquid sample sleeve, a liquid sample tank support and screws, wherein a hole for filling a liquid sample test tube is formed in the liquid sample tank support, the liquid sample sleeve and the liquid sample tank support are screwed, the connection surface of liquid in the liquid sample test tube and the tube wall right falls on a focus of a raman spectrum collection lens by regulating the liquid sample tank support to move front and back, an inner hole of the liquid sample sleeve and a collection lens barrel are matched and are positioned by virtue of the end surfaces, and the central position of liquid in the tested liquid sample test tube can be kept unchanged when being in rearranged every time. The portable laser raman spectrometer liquid sample measurement positioning device can conduct accurate positioning and is not required for mechanism regulation, samples are fast put at the best measurement position by one step, the maximum raman light signal of the samples can be fast obtained, the sample detection efficiency is high, and the portable laser raman spectrometer liquid sample measurement positioning device is applicable to various portable or small-size laser raman spectrometers, reasonable in structure, accurate to position, convenient to operate, and low in cost.
Description
Technical field
The utility model relates to laser Raman spectrometer, especially relates to a kind of portable laser Raman spectrometer fluid sample measurement and positioning device.
Background technology
Laser Raman spectrometer is that one utilizes laser as excitation source, the Raman spectrum producing by measuring sample, the instrument that carries out Matter Composition analysis.Because the Raman spectrum that sample produces is very faint, approximately only has 10 of laser excitation main line light Strong
-10～10
-6therefore how to make Laser Focusing point accurately drop on sample, can accurately drop in the focus of Raman spectrum collecting lens again, as much as possible improve the collection efficiency of Raman light intensity, become a major issue that needs solution in laser Raman spectrometer simultaneously.
On large-scale precision laser Raman spectrometer in the market, be all furnished with optics or videomicroscopy platform, by regulating the Precision trimming mechanism of X-Y-Z three-dimensional, can be positioned at solid sample or the fluid sample in detection platform by fine adjustment, make sample fast on best tram.So both can improve the collection efficiency of Raman light intensity, save again detection time, improve the detection efficiency of sample.But because microscope stage manufacturing cost is higher, volume is larger, is only suitable for using in large-scale instrument, is unsuitable for being used in portable instrument.
Medium-sized Portable laser Raman spectrometer, because instrument volume is little, cost is low, generally be not equipped with other servicing units, in measuring process, only depend on manually the front end that solid sample or fluid sample is placed on to laser probe, by the position of mobile example, search out a Best Point, make tester the Raman light signal of sample maximum can be detected.Although this method is simple, but operation inconvenience, needs usual test experience accumulation, each measurement need to just can be found a suitable position by repetitiousness test repeatedly, even professional is also difficult to find fast an optimum position, measure detection efficiency very low.
Summary of the invention
The purpose of this utility model is to provide and can accurately locates, regulate without mechanism, fast sample is settled at one go, be positioned over the optimum position of measurement, obtain rapidly the maximum Raman light signal of sample, thereby greatly improve and detect sample efficiency, applicable to various portable or miniature laser Raman spectrometers, a kind of portable laser Raman spectrometer fluid sample measurement and positioning device of the feature such as there is rational in infrastructure, registration, easy to operate, cost is low.
The utility model is provided with fluid sample sleeve, liquid sample pool support and screw;
Described liquid sample pool support is provided with the circular hole for packing fluid sample test tube into, between fluid sample sleeve and liquid sample pool support, be spirally connected, by regulating liquid sample cell support to move forward and backward, make the invisible spectro liquid of fluid sample and tube wall joint face just in time drop on the focus place of Raman spectrum collecting lens, the endoporus of fluid sample sleeve matches with collecting lens lens barrel and locates by end face, pass through screw, the utility model can be tightened up or be taken off, and reinstalls liquid center's invariant position that can keep in fluid to be measured sample tube at every turn.
The utility model can accurately be located, regulate without mechanism, fast sample is settled at one go, be positioned over the optimum position of measurement, obtain rapidly the maximum Raman light signal of sample, thereby greatly improve and detect sample efficiency, applicable to various portable or miniature laser Raman spectrometers, there is rational in infrastructure, registration, easy to operate, low cost and other advantages.
