Abstract
The present invention is concerned with the analysis of polar metabolites and provides methods for analyzing polar metabolites including extracting a biological sample with a extraction buffer containing a phase separator and a volatile neutral ammonium salt under conditions which allow for immediate disruption of cells in the biological sample, separating the polar metabolites in the extract by chromatography, and analyzing the separated polar metabolites. Moreover, a method for quenching a biological sample containing cellular material is contemplated.
