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.

“…Limits of detection were 2.3 and 0.70 mg L À1 for Sb and Bi, respectively and enrichment factors 534 and 192, respectively. An interesting collodion lm sample holder was tested by Kunimura et al 82 The spectrum 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. A river water sample was measured on the collodion lm sample holder, and 10.0 mg L À1 of Cr and 5.1 mg L À1 of Mn were detected.…”

Trace Determination of Cyanocobalamin (Vitamin B12) by Analyzing Cobalt Using a Portable Total-Reflection X-ray Fluorescence Spectrometer

“…Portable TXRF spectrometers, [8][9][10] which can be applied to on-site trace elemental analysis, have been developed since 2006. The dry residue of a solution sample on a sample holder, such as a quartz glass substrate, a diamond-like carbon (DLC) coated quartz glass substrate (DLC sample holder), 11 or a collodion film, 12,13 is analyzed by these portable spectrometers. A detection limit of 8 pg, 10 which was equivalent to 8 ng/mL in 1 μL of a sample solution, was obtained for chromium by using a portable TXRF spectrometer.…”

Trace Elemental Determination Using a Portable Total Reflection X-Ray Fluorescence Spectrometer with a Collodion Film Sample Holder

“…The method for preparing a collodion film sample holder was described elsewhere; 7 it is briefly summarized here. After a solution containing 2% of pyroxylin was prepared by diluting collodion (10%) (Wako Pure Chemical Industries, Ltd., Osaka, Japan) with 3-methylbutyl acetate, 5 μL of the solution was dropped on distilled water.…”

“…Yamaguchi et al 6 reported that the use of a silicon wafer sample holder covered with a polyester film is more useful for detecting the Al Kα and P Kα lines than a silicon wafer sample holder. Recently, we have used collodion film as a sample holder 7 for a portable TXRF spectrometer. 8 Because a collodion film sample holder can be produced at low cost, it can be used as a disposable sample holder.…”
