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 and J.T.Baker® standards and reagents are specifically produced to give you that blank background so that you can solve even the most baffling cases.

Chemicals for sample preparation

Ultrarene syrer og syrer med høj renhed

Et komplet udvalg af syrer med høj renhed med maks. Tilladte niveauer af fremmedlegemer i ppb og ppt, som er essentielle i applikationer med ultra-sporanalyse.

ARISTAR® acids for trace analysis

This high purity acid range is essential in sample preparation for metal trace analysis with max. permitted levels contaminants in ppm and ppb

Fluxes for XRF

Used for rocks, metals, ceramics and cement analysis. Digestion by fluxing is a common sample preparation step for XRF.

Mercury determination


Mercury is one of the most toxic and poisonous heavy metal in the environment. Its determination usually made by AAS is common in different sectors as Food, Environment and Pharma industries.
