Comply with California Prop 65 with HDXRF<sup>®</sup>
29 Jan 2019In 1986, California voters approved an initiative to address concerns about exposure to toxic chemicals. That initiative became the Safe Drinking Water and Toxic Enforcement Act of 1986, better known by its original name of Proposition 65 (Prop 65). It is a labeling rule and does not ban or limit chemicals. Proposition 65 requires that consumers have a “clear and reasonable warning” if they are being exposed to chemicals which are known to cause cancer and/or reproductive toxicity. The state is required to publish a list of those chemicals at least annually and it has grown to include approximately 900 chemicals since it was first published in 1987.

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.

Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.X-Ray FluorescenceX-ray fluorescence (XRF) is an analytical technique used to determine the elemental composition of materials. It is widely used in geology, materials science, and environmental testing for detecting heavy metals and other elements. Browse our peer-reviewed product directory to find the best XRF systems, compare products, check reviews, and get pricing directly from manufacturers.Environmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.Drinking Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).
