Mass Spectrometry

Methods

• low- and high-resolution MS
• ESI and MALDI ionization
• accurate mass by ESI-MS
• tandem MS
• LC/MS and LC/MS/MS
• electrospray mass spectrometry of biopolymers

Applications

• structure elucidation and verification
• purity and quality control
• elemental composition
• analysis of mixtures
• identification of modifications
• mass determination and purity checks of biopolymers
• sequencing of oligonucleotides
