Abstract
An electrostatic ion guide has been developed to transmit externally f ormed ions in chemical ionization mass spectrometry. Transport of ions over a distance of ten or more cm is accomplished with a high efficie ncy. Our design of the ion guide allows efficient separation of ion fr om neutral molecules, which provides a relatively simple means to sign ificantly increase the detection sensitivity in chemical ionization ma ss spectrometry.
