Metal trace analysis and detection
In metal analysis, elemental evidence is now gathered from the tiniest traces in the ppm, ppb and ppt ranges with sophisticated instrumentation like AAS, ICP-OES or, more recently, ICP-MS.
Rather than just looking – modern day laboratory sleuths can only rarely analyse a sample directly without suitable pre-treatment. The sample must be first skillfully dissolved, digested or fused. All the auxiliary reagents used must perform these tasks, but be effectively invisible in the final analysis.
VWR Chemicals, J.T.Baker® and Merck standards and reagents are specifically produced to give you that blank background so that you can solve even the most baffling cases.
