Measuring Silver in Antimicrobial Fabric with HDXRF<sup>®</sup>

XOS
7 Feb 2019

No one wants to make a stink. That’s why manufacturers are introducing premium innerwear and activewear using antimicrobial fabrics treated with a solution of silver ions to kill odor-causing bacteria. Fabrics treated with products such as Silvadur™ are effective as long as a minimum concentration of the silver remains after washing. The longevity of the treatment is partially based on the initial concentration applied to the fabric, so an important quality control test is to quantify the amount of silver found in the fabric. To comply with manufacturer standards of quality, a minimum concentration of silver is required based on the application, and HDXRF provides a reliable, low-cost, and non-destructive test for quality assurance programs.

Fluorescence SpectroscopyFluorometers and spectrofluorometers (also called fluorescence spectrometers) are used to measure the intensity and wavelength of fluorescent light emitted from a sample after excitation by illumination. Spectrofluorometers utilize monochromators to select the desired wavelengths, whereas filter fluorometers employ a set of filters. Spectrofluorometers for measuring steady-state fluorescence and lifetime fluorescence (or time-resolved fluorescence) are available, as well as fluorescence microscopes and microplate readers.

X-Ray diffractometers (XRD) are superior instruments in elucidating the dimensional atomic structure of crystalline materials, including powders, thin films and single crystals. For large unit cells or ordered macromolecules, consider small-angle X-ray scattering (SAXS). X-ray spectroscopic techniques include X-ray fluorescence (XRF) and X-ray photoelectron spectroscopy (XPS), both providing simple and accurate methods for determining the elemental composition of a material. Energy dispersive (EDXRF) and wavelength dispersive (WDXRF) XRF spectrometers are available, as well as handheld/portable devices. High-resolution, 3D microstructure characterization of materials can be achieved with X-ray microscopes combining sub-micron resolution imaging with 3D computed tomography.
