High-precision isotope analyses in forensic anthropology, nuclear forensics and food authentication applications, requires the generation of large data sets. A new, fully automated Sr purification method for the prepFAST-MC™ eliminates the sample preparation bottle neck. Reproducibility, reliability, recovery, blank and carry over are at required levels for the determination of Sr isotopes in a variety of natural samples. Potential applications of prepFAST-MC™ are illustrated by accurate and precise determination of Sr isotopes in rock, bone, and seawater reference materials.
Unattended, the prepFAST-MC™ can process up to 48 samples in 24 hours and, (depending on chemistry), collect several purified extractions from each sample.
Strontium recovery for 55 consecutive, fully automated extractions is plotted.
