A+ Single Element Standards

The VHG Labs A+ Single Element Calibration Standards are designed for use for ICP-MS, ICP-AES, AA and other spectrometric techniques. These high purity standards are unique in that they are assayed in accordance with the High Performance ICP (HP-ICP-AES) method that was developed by NIST. The HP-ICP-AES method ensures the highest accuracy standards available, which translates into better analytical results. Both the certified concentration and the uncertainty associated with it are directly traceable to the appropriate NIST SRM through an unbroken chain of measurements. A Certificate of Analysis that documents the traceability to NIST and also reports trace impurity levels accompanies each A+ Standard. VHG also offers consumables and supplies for ICP, AA, ICP-MS, GFAA and XRF.
