Automated Ultra-Trace Analysis using the contrAA® Dynamic Mode

This technical note details some of the key benefits featured in the contrAA^® Dynamic Mode. For ultra-trace analysis the contrAA^® yields detection limits up to an order of magnitude better than traditional AAS technology. The contrAA^® 800 series Dynamic Mode automates many key operations, enabling the connection of multiple calibration curves to provide a wide-range calibration over up to five orders of magnitude. This allows measurements of ultra-trace- and major elements in the same sample with a single method, thus offering a dynamic range similar to that of ICP-OES instruments.
