Mass spectrometry of biomolecules: from PDMS to MALDI

MALDI Mass Spectrometry of Synthetic Polymers

This paper reviews the application of matrixassisted laser desorption/ionization mass spectrometry (MALDI-MS) to the analysis of synthetic polymers, and includes data obtained by Toyota CRDL. In MALDI-MS of synthetic polymers, the selection of a matrix and cationizing agent, as well as the sample preparation techniques, are very important to obtaining a successful spectrum. MALDI-MS makes it po...

Using AP-MALDI Ion Trap Mass Spectrometry

Atmospheric pressure MALDI/ion trap mass spectrometry.

A new sample ionization technique, atmospheric pressure matrix-assisted laser desorption/ionization (AP MALDI), was coupled with a commercial ion trap mass spectrometer. This configuration enables the application-specific selection of external atmospheric ionization sources: the electrospray/APCI (commercially available) and AP MALDI (built in-house), which can be readily interchanged within mi...

Fish authentication by MALDI-TOF mass spectrometry.

Recent EU directives and regulations for quality control and authentication of food products have prompted the development of new methods for large-scale tests to ensure the protection of consumers. In view of this, an innovative method based on MALDI-TOF mass spectrometry has been developed and successfully applied to fish authentication. Highly specific mass spectrometric profiles from 25 dif...
