In this study a specific taste-modulating flavor ingredient, N-lactoyl ethanolamine, was determined in two Beerenauslese wines using preparative LC, as a first isolation and concentration step, followed by LC-MS/MS on a triple quadrupole in accurate mass (AM) mode. The accurate masses of the analyte and three characteristic fragments were determined with mass accuracies between 8 and 20 ppm. N-lactoyl ethanolamine concentrations in the wines were 0.4 and 2.5 mg/L. 
Liquid chromatography with accurate mass measurement on a triple quadrupole mass spectrometer for the identification and quantification of N-lactoyl ethanolamine in wine.
TLDR
A method is described to demonstrate that no potential cross-contamination from the reference target molecule had given rise to an incorrect positive identification of N-lactoyl ethanolamine in wine. Expand

Multi-residue pesticide analysis in fruits and vegetables by liquid chromatography-time-of-flight mass spectrometry.
TLDR
The high degree of confirmation for target pesticides by accurate mass measurements demonstrated the applicability of the method in routine analysis, and is a valuable indicator of the potential of LC-TOF-MS for quantitative multi-residue analysis of pesticides in vegetables and fruits. Expand
Screening and identification of unknown contaminants in water with liquid chromatography and quadrupole-orthogonal acceleration-time-of-flight tandem mass spectrometry.
TLDR
A procedure for the liquid chromatography-tandem mass spectrometry (LC-MS/MS) screening of water extracts was developed, enabling the detection and identification of compounds at levels < or = 0.25 microg/l in surface water. Expand

Diagnostic protein discovery using liquid chromatography/mass spectrometry for proteolytic peptide targeting.
TLDR
This peptide targeting method was superior to previous experiments using single sample MALDI analysis for protein profiling or proteolytic peptide profiling, because more potential protein markers were identified. Expand

TLDR
Mass spectrometry plays a key rôle in proteomics-associated analyses and this review describes that function in terms of the instrumentation used, the results generated, data interpretation and the advances in analytical techniques being made to deal with the production of highly specific, high throughput data.
