Method and Device for Transferring Ions for Mass Spectrometry Analysis
Summary
Purdue University researchers have developed devices and methods that provide enlarged flow to carry the ions from a distant sample to close to the MS inlet. The large flow conductance of the tube allow the gas carrying ions to move toward the MS inlet at a fast flow rate. Pumps with high flow rates, but low compression ratios, are used to generate the flow inside the tube. The proper pumps used for the coupling are different from those used for the mass spectrometer, which are typically of high compression ratio.
