MALDI-TOF mass spectrometry detects specific peptide peaks in cerebrospinal fluid to identify neurodegenerative diseases.
Circular and ring magnets create opposing fields to increase extracted ion beam amount in glow discharge mass spectrometers.
Ionizes source gas to generate primary ions, enabling detection of trace compounds with high ionization energy.
An atmospheric pressure ionization source enables rapid switching between liquid and gas chromatography modes on a single mass spectrometer.
