Portable Total Reflection X-ray Fluorescence Spectrometer with a Collodion Film Sample Holder

Abstract

Grazing incidence X-ray fluorescence analysis with a collodion film sample holder was performed by using a portable total reflection X-ray fluorescence spectrometer. The spectral background was low when using this sample holder, and a Cr detection limit obtained with this sample holder was comparable to that obtained with a diamond-like carbon coated quartz glass sample holder which was usually used as sample holder for the portable spectrometer. A river water sample was also measured with the collodion film sample holder, and 10.0 μg/L of Cr and 5.1 μg/L of Mn were detected. Collodion film sample holder can be used as a disposable sample holder for trace elemental analysis using the portable spectrometer.
