Advantages and Disadvantages of Ningbo Instrument X-ray Fluorescence Spectrometer

X-ray fluorescence instrument disadvantages revision bill Spectrometer

advantage

a) The analysis speed is high. The time required for the measurement depends on the precision of the measurement. After 2 to 5 minutes, all the tested elements in the sample can be measured.

b) X -ray fluorescence spectroscopy has nothing to do with the chemical bonding state of the sample, but also basically does not matter with the solid, powder, liquid and crystalline, amorphous and other substances (gas sealed in the container can also be analyzed) but at high resolution In the precision measurement of the rate, a phenomenon such as a wavelength change can be seen. Especially in the ultra soft X -ray range, this effect is even more pronounced. Wavelength changes are used for the determination of chemical sites .

c) Non-destructive analysis. No changes in the chemical state will occur during the measurement, nor will the sample fly. The same sample can be measured repeatedly and the result is reproducible.

d) X -ray fluorescence analysis is a physical analysis method, so elements that are chemically identical can also be analyzed.

e) High analytical precision.

f) Simple preparation, solids, powders, liquids, etc. can be analyzed.
2. Disadvantages

a ) Difficult to make absolute analysis, so quantitative analysis requires standards.

b ) The sensitivity to light elements is lower.

c ) susceptible to mutual elemental interference and superimposed peaks.
