ABSTRACT:
A method of obtaining ions of an analyte is disclosed. The method includes aerosolizing a sample using a thermal liquid jetting device or a piezoelectric liquid jetting device to obtain an aerosol without ionizing the sample. The sample includes the analyte in a solvent. The method further includes drying the aerosol to obtain gas phase solvent and gas phase analyte, and ionizing the gas phase analyte to obtain ions thereof. An ion source using the method for obtaining ions of an analyte is also disclosed.
