LECO has added a -100 mesh Ultra High Purity Graphite Powder and a Fly Ash Carbon Concentrate material to the existing standard offerings. The -100 mesh UHP Graphite Powder, with a certificate value (lot 1000) of 100% (+/- 0.3%), is ideal for calibrating SC organic combustion instruments for coal, coke, graphite, carbon black, or other high carbon applications. The 502-843 Fly Ash Carbon Concentrate standard is a unique co-product material of a fly ash beneficiation process resulting in a material containing a mid-level carbon composition (~42%) with sulfur and mercury values typical of a fly ash material also on the certificate.
