Researchers at Purdue University have developed a new method for generating ionic wind in mass spectrometers. Traditionally, a gas is moved through a container by conventional pumps which can exhaust the gas. Purdue researchers introduce ionic wind moves directionally from high to low voltage at speed between 0.1-1.5 m/s, a uniquely noninvasive approach. This setup allows for smaller vacuum pumps and power supply units in mass spectrometers and similar equipment.
