Automated Sample Prep Methods for Mixing and Centrifugation:

This poster describes two applications that benefited from centrifugation in the sample extraction and clean-up, using Element’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 implement fully automated sample prep for complex LC and GC applications.



Element Application Notes:

Element (and our partners) regularly produce Application Notes. These cover a wide and diverse range of methods, techniques, applications, and related chromatography technology. Our Application Notes provide detailed technical information, unique applications insight and method development & validation, as well as systems configuration innovations to ensure readers can further their knowledge in an engaging way. For many years, Element’s Application Notes have helped and supported analytical chemists in the fields of Gas Chromatography – GC, Liquid Chromatography – LC, and Mass Spectrometry – MS achieve to develop analytical solutions. Visit our Applications Note page to search for the insight you need in the following categories: Matrix, Technique, Analyte, Instruments, Product, Industry. Or alternatively, CONTACT US for more information or to put forward an Application Note subject and our Applications Team will be happy to support you in any way they can.
