Separation of Different Mass/Charge Ions in Air
Researchers at Purdue University have developed a simple new instrument where all steps of ion formation, ion focusing, ion reaction, ion separation, and ion detection are performed in air. Ion transport and focusing was achieved with a zigzag system of curved electrodes. What differentiates this device from current solutions in the marketplace is the separation of ions of different mass/charge ratio in air, as well as, the use of a single integrated instrument to perform ionization in air, ion transport from the source to the detector in air while accomplishing ion focusing, and ionic reactions and ion detection in air. Eliminating the need for a vacuum system simplifies the mass spectrometer, providing the potential for cost reduction.
