Safety, efficacy and content labeling are key requirements in the food industry. At-line or near-line monitoring of production processes improve cost savings by decreasing waste, rework and materials costs. The US FDA, the European Union and various other entities around the world strictly regulate the allowable concentrations of heavy metals in food, drugs and other products and packaging; for example, the over-the counter (OTC) pharmaceutical regulations for cosmetics in the U.S. Rigaku supplies a wide range of dedicated X-ray Fluorescence (XRF) instruments for elemental analysis and X-ray Diffraction (XRD) instruments for phase and structural analysis for both R&D and production applications. Rigaku’s Small Angle X-ray Scattering (SAXS) instruments are the perfect solution for particle size analysis of optically opaque formulations.
