X-Ray Fluorescence Analysis of Light Elements in Liquid Samples – EDX-8100 and Helium Purge Unit –

Introduction

Shimadzu’s EDX-8100 is an energy dispersive X-ray fluorescence spectrometer with high sensitivity for light elements and can be configured with an optional helium purge unit. The helium purge unit enables high-sensitivity analysis of light elements in samples that cannot be depressurized to a vacuum state such as solutions and samples that generate gas. As one effect, detection of fluorine (F) in liquid samples is possible with the EDX-8100, whereas it was not possible with the conventional EDX-8000. The detection limits of the elements F to K in liquid samples in a He atmosphere and differences depending on the film used to hold the samples were evaluated.
