SpectroCertified® organo-metallic concentrated standard solutions are formulated with a proprietary chelation and stabilization solution to avert metallic content precipitation out-of-solution. The starting materials are representative of ultra-pure reagents certified against NIST standard reference materials, whenever available. The solution standards do not contain phosphorus or sulfur, unless otherwise noted. They are particularly useful in formulating sets of standards for the analysis of additive elements in lubricating oils; nickel and vanadium in residual and wear metals in oils by x-ray fluorescence (XRF) spectroscopy. They are inter-miscible for optional preparations of diluted standards or for multi-element formulations for plasma emission (ICP or DCP), rotating disk (rotrode) or atomic absorption (AA) analyses. Each item is accompanied with a Certificate of Analysis that documents any trace impurities.
Stabilized and “ready-for-use” as supplied:
