Description
Technical field
The utility model relates to a kind of testing of materials analysis technical field, especially relates to a kind of solid sample holder for sepectrophotofluorometer.
Background technology
Sepectrophotofluorometer is a kind of instrument that can be used for testing the fluorescence spectrum that fluorescent marker sends.It can provide and comprise many physical parameters such as excitation spectrum, emission spectrum and fluorescence intensity, quantum yield, fluorescence lifetime, fluorescence polarization, reflects the fluorescence property of material, the Cheng Jian of molecule and structure situation from all angles.By the mensuration to these parameters, not only can do general quantitative analysis, but also molecule conformation change under circumstances can be inferred, thus illustrate the relation between molecular structure and function.The excitation wavelength sweep limits of sepectrophotofluorometer is generally 190 ~ 650nm, and emission wavelength sweep limits is 200 ~ 800nm.Can be used for the spectral scan of liquid.
The general principle of sepectrophotofluorometer is, the ultraviolet light sent by high-pressure sodium lamp or xenon lamp and royal purple light are irradiated in sample cell through optical filter, fluorescent material in excited sample sends fluorescence, fluorescence is after filtering and reflecting, 's accept by photomultiplier, then to scheme or the form of numeral shows.
The generation of material fluorescence becomes excitation state after the material molecule being in ground state under normal conditions absorbs exciting light, these molecules being in excitation state are unstable, in the process returning ground state, the energy of a part is released again in the form of light, thus produce fluorescence.
Different material is due to the difference of molecular structure, the distribution of its excited level has features different separately, this feature is reflected in and fluorescence shows as various material has its characteristic fluorescence excitation and emission spectra, therefore can carry out the qualification of material qualitatively by the difference of fluorescence excitation and emission spectrum.
In the solution, when the concentration of fluorescent material is lower, the concentration of its fluorescence intensity and this material has good proportional relation usually, i.e. IF=KC, utilize this relation can carry out the quantitative analysis of fluorescent material, similar with UV-VIS spectrophotometry, fluorescence analysis also adopts calibration curve method to carry out usually.
At present, on market, the sepectrophotofluorometer major design of main flow carrys out test liquid sample, what equipment was equipped with is all liquid sample stand, in actual use, also sepectrophotofluorometer test powders sample can be used, but, because sepectrophotofluorometer is not equipped with solid sample holder, need buy separately or make solid sample holder, expensive, and existing solid sample holder is mostly the sepectrophotofluorometer for a certain model, there is no versatility, in addition, solid sample holder needs the placed angle adjusting solid sample holder when putting into sample cell, the ultraviolet light that high-pressure sodium lamp or xenon lamp are sent and royal purple light be irradiated to solid sample makes solid sample send fluorescence and can accept by photomultiplier, because existing solid sample holder does not have firm banking, all directly put into sample cell in use, then placement location and angle adjustment period of artificial, and test all can carry out many groups usually, artificial placement and adjustment make the placement location of solid sample holder and angle all inconsistent, this can make many group measuring result error larger, the test result finally obtained is accurate not.
