Common Background Contamination Ions in Mass Spectrometry
In this poster, the accurate mass of elements, organic solvents and all potential contaminant ions observed in mass spectrometry are listed in 12 useful tables to help troubleshoot potential contamination in LC-MS systems.
Common background contamination ions encountered in mass spectrometers are polyethylene glycol, polypropylene glycol, phthalates, organic solvent clusters, solvent modifiers, fatty acids, metal ions, tritons, tweens and siloxanes. Metal ions form adducts with varying numbers of substrates to give characteristic ESI+ ions. Such common contaminant groups are split over 12 separate tables for easier investigation.
