An electrode network for N parallel ion traps, wherein N is an integer larger than 1, includes at most 2N+2 electrodes, which form N trapping volumes each corresponding to a respective one of the N parallel ion traps. Also provided is a parallel mass spectrometer, comprising: a vacuum chamber and a network of at most 2N+2 electrodes disposed in the vacuum chamber and held in fixed positions with respect to each other, the network of electrodes forming N trapping volumes each corresponding one of N parallel ion traps. The network of electrodes may be arranged in first and second rows of electrodes. A plurality of detectors is positioned to receive ions ejected from the trapping volumes through spaces between adjacent electrodes in the first row of electrodes.
