Q.109
Orbitrap technology is mainly used for the determination purpose of
- Orbitrap Mass Spectrometer Capabilities:
- The Orbitrap mass analyzer (invented by Alexander Makarov) captures ions in electrostatic oscillation around a central spindle electrode, determining $m/z$ from the harmonic axial oscillation frequency.
- It is globally celebrated in metabolomics and pesticide residue analysis for providing ultra-high mass resolving power ($\gt 100,000$ to $500,000$) and sub-ppm accurate mass measurement, enabling unambiguous elemental formula determination of unknown analytes.
- Conclusion: Orbitrap is primarily used for Accurate Mass determination (Option 1).
Correct option: (1) Accurate mass
