Prepare.
Background technology
Xray fluorescence spectrometer is a kind of detecting instrument that elemental analysis is carried out using fluorescent X-ray, and it can
It is enough that quantitative analysis is carried out to material, qualitative analysis can also be carried out.Therefore, Xray fluorescence spectrometer be widely used to it is biological,
In the ambits such as medical science, material, each development about subject is promoted.
At present, when detecting powder sample using Xray fluorescence spectrometer, 3.5 centimetres of diameter, thickness are generally compressed into
2 millimeters of fine and close sheet standard sample.When detecting little power, because the volume of powder is not enough, standard can not be generally prepared
Sample.Traditional solution be added in little power powder adhesive known to a certain amount of composition with it is to be measured micro
Powder is mixed, to prepare standard sample.But there is three below shortcoming using binding agent, first, the addition of binding agent is introduced into
New impurity, increases analytical error；Second, it can cause the intensity of spectral line because of being diluted for the low element of concentration or light element
Step-down, if adhesive particle degree is larger, can also cause grain dispersion, so that without quantitative analysis.3rd, binding agent plus
Membership declines analysis line strength, the Monitoring lower-cut of influence light element and trace element.Therefore, the present invention specifically addresses tradition
The drawbacks of little power sample preparation methods are brought.
