Inlet ionization: Polar molecules including peptides and medium-sized proteins

Inlet ionization[5] complements DART by allowing the operator to analyze polar and charged compounds.  The sample can be aspirated directly from solution into orifice 1, or a matrix (3-nitrobenzonitriile) can be added to induce ionization.
