文摘

A miniature cylindrical ion trap mass spectrometer isdescribed, and preliminary data are presented. Functionality and performance of laboratory-scale instrumentshave been maintained to the extent possible in thisbattery-operated mass spectrometer. Capabilities includetandem mass spectrometry experiments. Custom-designed electronic components include the RF scanningand amplification system, data acquisition components,and lens power supplies, as well as a custom-softwareapplication. Direct leak and membrane introduction inletsystems are used for sample introduction. A mass/chargerange of ~250 Th with unit mass resolution has beendemonstrated.
