Sample preparation for X-ray fluorescence analysis VII.　Liquid sample

We have discussed about the feature of X-ray fluorescence analysis (XRF) which is quick and nondestructive analysis of liquid, solid and powder sample in the previous issues. In this paper, analysis examples of liquid samples are shown. Careful attention is required for handling of liquid sample, because there are many kinds of liquids such as water solution, organic solvent, oil, etc., and each one has various kinds of properties such as acid, alkaline, etc. In this issue, analysis method for liquid samples by wavelength dispersive X-ray fluorescence analysis spectrometer (WDX) is discussed.
