Single stage reversed-phase liquid chromatography-mass spectrometry for the characterization of triglyceride positional isomers.
Poster Nov 12, 2009
The high level of selectivity afforded by RP-HPLC in combination with CID allowed recognition of eight groups of TAG positional isomers. Development of UPLC approach has reduced the run time by half while maintaining separation. The improved method combined with principal components analysis was used to assess the extent of variation of major TAGs in subcutaneous and intermuscular pork fat from four different locations of adipose tissues.

Fast Pesticide Residue Analysis Using a Novel Benchtop Time-of-Flight Mass SpectrometerPoster
The objective of the study was to maximize throughput without introducing a significant number of additional chromatographic co-elutions not separable by deconvolution, whilst transitioning from a standard 30 m column to a 15 m column using LECO's software.READ MORE
