Daszykowski M, Danielsson R, Walczak B.
PMID: 18384796
J Chromatogr A. 2008 May 23;1192(1):157-65. doi: 10.1016/j.chroma.2008.03.027. Epub 2008 Mar 15.

Hyphenated techniques such as capillary electrophoresis-mass spectrometry (CE-MS) or high-performance liquid chromatography with diode array detection (HPLC-DAD), etc., are known to produce a huge amount of data since each sample is characterized by a two-way data table. In this...

Bioinformatics. 2010 Jun 15;26(12):1574-5. doi: 10.1093/bioinformatics/btq171. Epub 2010 Apr 22.

UNLABELLED: Identifying biologically significant changes in protein abundance between two conditions is a key issue when analyzing proteomic data. One widely used approach centers on spectral counting, a label-free method that sums all the tandem mass spectra for a...

Threshold collision-induced dissociation measurements using a ring ion guide as the collision cell in a triple-quadrupole mass spectrometer.

Analytical chemistry

Anal Chem. 2009 Aug 15;81(16):6805-12. doi: 10.1021/ac9009758.

A triple-quadrupole mass spectrometer has been modified for bond-dissociation energy measurements via threshold collision-induced dissociations (TCIDs) by replacing the conventional collision cell with a ring ion guide. Optimal operating conditions for the ring ion guide were determined or derived,...

Anal Bioanal Chem. 2009 Jan;393(2):427-9. doi: 10.1007/s00216-008-2212-8. Epub 2008 Jul 08.

Mass filters for miniature mass spectrometers are now being constructed using three-dimensional microfabrication techniques. Crossed-field, travelling-wave, time-of-flight, quadrupole and cylindrical ion-trap filters have all been demonstrated, with steadily increasing mass range and mass resolution. This paper reviews the range...
