Sample preparation
The AMS analysis require sample processing and separation of carbon inherent to the formation of studied material. The process of extraction suitable carbon or removing the contaminants is called sample pre-treatment. In the next step extracted carbon is either combusted (oxidized) or released in acidification (carbonates, water) and dependent on the sample size Graphitized or directly analyzed in the Gas Ion Source.
Original samples are photographed and investigated under binocular (left). The final, clean material ready for combustion in Elemental Analyzer and subsequent graphitization (right).
