TraceSELECT^® / TraceSELECT^® Ultra

Reagents for Trace Analysis

Sample prep for trace analysis applications requires reagents of highest purity. Specifically, they must have very low metal content to ensure appropriately low blanks. Fluka-brand TraceSELECT^® and TraceSELECT^®Ultra reagents from Sigma-Aldrich include high purity acids, bases and salts that are designed for trace and ultra-trace analysis. These reagents are handled under clean-room conditions and supplied in Teflon PFA bottles to ensure long-term purity.


TraceSELECT^®Ultra

TraceSELECT^®Ultra products are designed for the ultra-trace analysis at ppb and even ppt levels. Typical metal trace impurities are below 0.1 µg/kg (<0.1 ppb), in some cases even as low as the ppq level. To maintain purity, TraceSELECT^®Ultra products are delivered in Teflon PFA bottles.
