EDX-7200 New Primary Filter-Quantitative Analysis of Titanium Dioxide in Antibacterial Coatings -

User Benefits

- EDX-7200 can nondestructively analyze coatings. - The amount of titanium dioxide can be determined by thin-film FP method. - The new primary filter is effective for analyzing Ti to Co (energy range: 4~8 keV).

Introduction

With growing interest in hygienic products, various antibacterial products have recently been developed. Due to titanium dioxide’s relative safety and photocatalytic capability, titanium dioxide coatings are being applied as antibacterial coatings in both indoor and outdoor products. However, there is also concern that the coating may come off as a result of rubbing or wiping with a solvent like alcohol. Energy Dispersive X-ray Fluorescence Spectroscopy (EDX) is effective at measuring titanium dioxide coatings because it does not require cumbersome sample preparation and can analyze samples nondestructively. The newly launched EDX-7200 comes standard with a series of primary filters that are effective for trace element analysis, and the newly installed filter is especially effective for the analysis of Ti to Co. In this application note, we present examples of titanium dioxide photocatalytic coatings applied on resins and subsequently analyzed for coating amount before and after wiping with chlorine disinfectant and alcohol.
