Abstract
An ion trap mass analyzer includes an elongated tunnel that has a wall, a longitudinal axis and an inner space. The wall includes a substrate and conductor trace patterns. There is also a variable electric potential means for providing electric potentials which is connected to the conductor trace patterns. The conductor trace patterns and the variable electric potential means provide a variable electric field within the inner space of the tunnel for transferring, storing, and analyzing ions.
