Sample preparation of environmental samples for trace metal analysis

A technical note is available from Analytix that highlights using a Milestone Ethos UP microwave digestion system to compare recoveries of three certified reference environmental materials using two different rotors. The system employed a contactless temperature sensor for both rotors and the high pressure 15 place rotor also featured patented ‘vent and reseal’ technology for controlling the internal pressure of each vessel.

The analytical results showed full recovery of the elements reported in the material reference certificates coupled with low RSDs. This data demonstrates that the Ethos UP is fully compliant with the three EPA methods for environmental samples using both rotor systems. In addition, the digestions were completed in a fraction of the time of a traditional hot-block method and used significantly less amounts of acids.
