Description

Polyolefin sample cup for X-ray fluorescence spectrum analysis tabletting sample preparation

Technical Field

The utility model relates to a polyolefin sample cup technical field specifically is a polyolefin sample cup that is used for X fluorescence spectral analysis preforming system appearance.

Background

As a relatively mature component analysis means, X fluorescence spectrum analysis is widely applied in the fields of geology, metallurgy, environment, chemical industry, materials and the like. The analysis objects of the method are mainly three types, namely bulk solid, powder and liquid, wherein the powder is the most analyzed one. Since many samples such as cement, coal, dust, etc. are powders themselves, bulk solids with irregular shapes are often pulverized into powders due to the immaturity of direct analysis techniques. The liquid sample can be put into a liquid sample cup for analysis, but the liquid is sometimes converted into a solid due to the reason that the liquid sample cannot be vacuumized, and the like, and the result of some pre-separation and enrichment is also often powder, so the sample preparation technology of the powder sample is an important research topic in X fluorescence spectrum analysis.

There are two main methods for preparing powder samples for X-ray fluorescence spectrum analysis: powder tableting and melting. The melting method can better eliminate the influence of the granularity effect and the mineral effect, but the melting method also has the defects that: the measured strength of the light element is reduced as the sample is diluted and absorbed by the flux; the sample preparation is complex, and a large amount of time is spent; the cost is also high. The powder tabletting method has the advantages of simplicity, rapidness, economy, common application when the analysis workload is large and the analysis precision requirement is not high, and is also commonly used for analyzing trace elements. In practical applications such as analysis of cement and rock samples, the powder tabletting method is a widely used XRF sample preparation method.

Typically, powder tableting is compression of a powder sample into a mold to make a coupon or directly into an aluminum or plastic injection molded sample cup. In the sample preparation process using the mold, when the pressure is removed from the mold, the sample often cracks, which affects the detection result, because the sample ring has slight deformation under high pressure, and meanwhile, the sample piece prepared by using the mold is easy to drop sample residues during the test, so that the X-ray tube is polluted. In the sample preparation process using the aluminum sample cup, in order to increase the strength of the sample piece, or when only a small amount of powder sample is used, the substrate sheet needs to be edged with polyethylene or boric acid, which makes the sample preparation procedure complicated and takes a lot of time for cleaning the sample cup. Still a bubble plastic cup can directly put into the powder, and direct preforming, but ordinary foaming bubble plastic cup has certain elasticity, and the pressfitting back edge is easy and the sample separation, can't laminate well, leads to the sample juncture to produce the crackle for the sample has the risk of drawing of patterns.
