Determination of Selenium and Zinc in Hair and Serum of Companion Animals by PIXE Method

We examined the concentration of selenium and zinc in hairs, sera and feeds using a Particle Induced X-ray Emission (PIXE) analysis. In the pre-treatment of animal hair, it was shown that the radio-frequency heating (RF) ashing method using the Teflon container for tightly sealing and nitric acid is...

Description
Summary:We examined the concentration of selenium and zinc in hairs, sera and feeds using a Particle Induced X-ray Emission (PIXE) analysis. In the pre-treatment of animal hair, it was shown that the radio-frequency heating (RF) ashing method using the Teflon container for tightly sealing and nitric acid is advantageous compared to the conventional wet ashing methods with Kjeldahl flask. The Se concentrations of the sera and hairs in cats were found to be higher than those in dogs (Mann-Whitney's U-test ; p
