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.
To analyze samples properly, they need a suitable pre-treatment. A sample must first be dissolved, digested or fused. All the auxiliary reagents used must perform these tasks, but be invisible in the final analysis.
Avantor®, 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.

Atomic spectroscopy lets analysts determine the composition of liquid or solid samples by measuring the amount of light absorbed by atoms and ions in the material at specific wavelengths.
By applying electromagnetic radiation to a compound, it puts atoms in the sample into an excited state. As they return to their original condition, they emit energy as light. By measuring the wavelength and intensity of the emitted light, analysts can identify the atoms in the sample.
