Automated sample preparation methods offer substantial benefits to any laboratory seeking to maximise the efficiency of workflows and the accuracy of analytical results.

Therefore this edition of Application Note ReView takes a look back at AS160 –  Automated Sample Prep Methods for Mixing and Centrifugation.

This poster describes two applications that benefited from centrifugation in the sample extraction and clean-up.

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 it is possible to implement fully automated sample preparation methods for complex LC and GC applications.
