Description
Technical field
The utility model belongs to the transmission spectral analysis field, relates in particular to a kind ofly to be used for the light path of quality of agricultural product analysis and sample accommodating is adjustable and the solid sample pond that can eliminate the edge parasitic light.
Background technology
Modern near-infrared spectrum analysis can not carry out any processing to sample, directly solid samples such as seed, powder is analyzed.Sample cell is between light source and monochromator and detecting device in transmission spectral analysis, and the light that light source produces enters monochromator after by sample cell and detecting device is analyzed.When conventional solid sample is done the spectral transmission analysis, mainly there is the problem of following three aspects:
1, analysis luminous energy and light path (promptly analyzing the distance of light process in the sample) exponent function relation by sample, therefore very big to the influence of analyzing, because the state (as powder sample, seed sample) of agricultural product sample is different with shape (seed, size), require difference very big to what analyze light path, generally require between 3-40mm approximately.In order to adapt to the difference of these samples, traditional spectrometer need be equipped with the several samples pond.
2, because the difference of sample size, the volume of sample cell also there are different requirements, generally require several to arrive the dozens of cubic centimetre approximately.In order to adapt to the difference of these samples, traditional spectrometer also needs to be equipped with different sample cells in addition, has improved instrument cost, and uses inconvenience.
3, after sample cell was deposited the seed sample, owing to have the space between the pool wall of seed and sample cell, analyzing light during tem analysis became the parasitic light that was leaked by the edge by these spaces, is directly detected by detecting device, has influenced the result who analyzes.
The utility model content
The purpose of this utility model is to provide a kind of can be the light path of one and the adjustable solid sample pond of sample accommodating with multiple functions set such as regulating light path, adjusting sample accommodating and elimination sample cell edge parasitic light.
The utility model comprises the sample cell body that is made of a cylinder that has an internal thread, its characteristics are: the top of sample cell body is the internal diameter of base pool body promptly removes the external cylinder of base pool less than its bottom internal diameter, Chi Tizhong puts into the some light modulation journey/volume packing rings and the optical glass window of combination, be fixed in the sample cell body by tight loop again, wherein, the external diameter of packing ring is consistent with the bottom internal diameter of sample cell body, the internal diameter of packing ring is consistent with the top internal diameter of sample cell body, so that can put into the pond body, constitute the sample cell of different light paths and volume with the base pool body portion together, washer height can be regulated, so that select the washer combinations of differing heights on request for use, the light path of sample cell that adjusting constitutes; The bottom internal diameter of optical glass window diameter and sample cell body is consistent, in order to the carrying sample, simultaneously as at the bottom of the sample cell; Tight loop has external thread, and the internal thread size of its size and sample cell body is supporting, so that be screwed into the sample cell body by screw thread, in order to the fixed optics glass sheet.
Described last a slice packing ring is taper type, outside consistent with light modulation journey/volume packing ring trimming edge parasitic light packing ring for inside, and its external diameter is consistent with the bottom internal diameter of sample cell, and the top internal diameter needs greater than the bottom internal diameter.When sample was packed sample cell into, the taper type packing ring can guarantee the closely combination in the marginal portion, the influence of the parasitic light that sees through with elimination to detecting.
Certainly, also can be by scribble the light tight annulus of 2-5mm at described optical glass window edge, this light tight annulus can block the sample cell edge and leak the parasitic light of coming, thereby eliminates the influence of parasitic light to detecting.
Can also be the purpose that the taper type structure reaches the elimination parasitic light by described tight loop being made inside.
Described optical glass window thickness is between 1-3mm, and material is neutral optical glass.
The gross thickness that described light path equals used packing ring adds the base pool body degree of depth of sample cell pond body front end, its scope can be between 3-40mm the interval with 1mm adjustable continuously.
The utility model cooperates with the light source that is equipped with in addition, monochromator, detecting device etc., the transmission spectral analysis system that can form sample, can more accurate scanning samples spectrum, so that the component in the analytic sample more accurately, that this sample cell in use has is easy to operate, the dress calibration really, be easy to control characteristics such as light path.When carrying out sample spectra scanning, light path and sample cell volume can be set on request, avoid needing to design and provide the sample cell of all size, save cost effectively and can reach desirable effect.
