Easy analysis of copper in seawater

Wow, it's been busy. Got a new ICP mass spec with some new features not seen before on any previous ICP mass spectrometers. Now, for the first time ever, copper can be analyzed in a matrix of salt water without any matrix removal, all while keeping the detection limit below the EPA action limit. Also, no internal standard suppression more than 60%. Since we don't write papers for journal submission, I'm announcing this to the chemistry community here.

Important factors in the analysis include a specific nebuliser optimization, cones that are water cooled, but are allowed to be at a higher temperature than previous models, and a really long rinse time.

Any chemist out there that are analyzing copper in seawater on ICPMS, inquire here for smooth analyses.
