Concrete technological means can adopt spectroanalysis instrument that several points of some analysis faces of sampling sample are analyzed; Therefore, on sample, select suitable several points to analyze and just seem very crucial.
Material spectrum analysis with the scolder industry is an example, material spectrum analysis with most of industries is the same, existing spectral analysis sample mostly still is solid cylindrical structural, selects the several points on the crossing seamed edge in the face of cylinder and upper surface to carry out the spectral analysis of material usually only.
But, no matter be the aura mass spectrometer, or spark direct-reading spectrometer, because sample as negative electrode, with copper pipe or copper rod as anode be to place in opposite directions, have small distance between two electrodes, when analyzing, to be analyzed of sample contacts with anode, and operating personnel can't accurately observe and be provided with the accurate position of shot point.
Therefore, prior art still haves much room for improvement and develops.
The utility model content
The purpose of this utility model is, a kind of locating device of spectral analysis sample is provided, and can improve the accurate positioning of sample or sample, shortens the sampling process time of analysis face.
The technical solution of the utility model is as follows: a kind of locating device of spectral analysis sample is used on the worktable of spectroanalysis instrument; Wherein: comprise a location-plate; Location-plate is provided with breach; The side of breach is the plane.
The locating device of described spectral analysis sample, wherein: the shape of breach is in the shape of the letter V.
The locating device of described spectral analysis sample, wherein: the shape of location-plate is set to square; The axis of the both sides phase square shaped location-plate of V font breach is symmetrical arranged.
The locating device of described spectral analysis sample, wherein: the angle on V font breach both sides is set to the right angle.
The locating device of described spectral analysis sample, wherein: the worktable surface of the lateral vertical spectroanalysis instrument of breach is provided with.
The locating device of described spectral analysis sample, wherein: the upper surface of location-plate is provided with leg-of-mutton boss; A wedge angle of triangle boss points to the edge of breach.
The locating device of a kind of spectral analysis sample provided by the utility model, owing to adopted location-plate to be provided with breach, side plane by breach is positioned on the circular outer wall of analysis face, thus when analyzing, to be analyzed rounded edge of cooperation sample contacts with the conical conical surface of anode and contacts, thereby do not need operating personnel accurately to observe and the accurate position of shot point is set, sampling process time of the face of analyzing has also been shortened in the accurate positioning that has improved sample or sample.
