XRF Calibration Standards

Available Elments            Certification Sheets            ISO/IEC 17025

nanoXRF offers a full range of thin film standards ofbrochures elements and compounds for use in calibration of x-ray fluorescence equipment. These standards are most often used for instrument calibration and quality control in various industries. They are also useful as a source of pure element spectra for use in background subtraction routines, and as a routine check of x-ray detector resolution and overall system performance. nanoXRF specializes in hard to find standards for very demanding applications in university/industrial R&D, air/water/soil pollution control, cancer R&D, ROHS/WEEE compliance, oil contamination, and various manufacturing industries such as automotive, semiconductors, flat panel displays, solar cells, batteries/fuel cells, pharmaceuticals, petroleum, disk drives and military.
Our state-of-the-facilities enable us to manufacture standards for 69 elements with areal densities from a few nano-grams/cm2 to tens of milli-grams/cm2 including five in-stock thicknesses. nanoXRF standards are available for almost all XRF instruments requiring nucleopore, mylar, polypropelene, other backings and A25, B25, A32, B32, A36. B36, A47 and B47 mounting options. nanoXRF standards are prepared by high vacuum deposition under precisely controlled environment resulting in highly accurate standards. Raw materials used are 99.9% pure or better. Each piece of manufacturing and certification equipment is periodically calibrated. The consistency and accuracy of nanoXRF standards is guaranteed by a certification process involving 5 levels of quality control as listed below:

Each nanoXRF standard is measured in-situ during manufacturing with a resolution of 1 nanogram.

Each nanoXRF standard is measured with a high precision balance with a resolution of 100 nanograms.

Each nanoXRF standard is measured with a XRF instrument to confirm the standard accuracy.

Each nanoXRF standard is measured by XRF to guarantee absence of contamination.

Each nanoXRF standard is compared against other XRF standards to >95% agreement.
