High Resolution Mass Spectrometry Unit


The High Resolution Mass Spectrometry Unit provides ICIQ researchers with access to state-of the-art mass spectrometry instruments capable of characterizing the wide range of compounds which are typically of interest in the institute. The instrumentation includes a variety of ionization options, sample introduction and chromatographic techniques required for mass spectrometry analysis of organic and organometallic compounds, including polymers, nanoparticles, non covalent interactions and mechanistic studies.

The MS Unit provides comprehensive training for ICIQ researchers to ensure optimal use of the facility and appropriate data interpretation, including periodic talks on practical aspects of MS.

In 2016, there were 2544 samples submitted, most of them to obtain accurate mass (87%).

Most of the samples (80%) were analyzed using electrospray as ionization method. The use of MALDI ionization has decreased from 9 to 5 % while APCI has increased from 5 to 14%.
