This poster describes two applications that benefited from centrifugation in the sample extraction and clean-up, using Anatune’s solvent safe CF200 centrifuge. The first method was a methanolic extraction of soils for the analysis of BTEX followed by GC-MS analysis. It showed good linearity for benzene, ethyl benzene, toluene, and the xylenes. The other was a pharmaceutical application for the dissolution and extraction of a tablet for HPLC analysis. This method showed excellent repeatability with a %rsd of 0.7% (n=9).
This application shows that by using the CF200 Centrifuge and mVorx vortexer instrumentation, it is possible to fully automate difficult sample preparation for LC and GC applications.
