Bulk analysis by wet chemistry

Wet chem lab

The most accurate means to obtain the bulk composition of certain major components a rock or meteorite remains classical gravimetric and colorimetric analysis. Our "wet" lab is fully equipped to handle problems that demand high accuracy, such as characterization of standard materials as a benchmark for instrumental methods.

Ferrous Fe determination by potassium dichromate titration is routinely performed as part of our standard bulk analysis, typically as a complement to X-Ray fluorescence results.
