Performance evaluation of polarity switching for plasma untargeted metabolomics using Orbitrap mass spectrometer.
Untargeted metabolomics often requires separate positive and negative ionization mode injections to maximize metabolome coverage, increasing analytical time, analysis cost, and complexity. Polarity switching (PSW) represents a promising alternative, yet its adoption in untargeted metabolomics remains limited, likely du...
