A modified Mattauch-Herzog analyzer is developed for positive ion measurements in the mass range 12 to 500 units and is upgraded for negative ions. It is to be applied in the identification of less abundant stratospheric ions. The main characteristics, design parameters and first laboratory test results obtained with it are described. The ions are mass separated in combined toroidal electrostatic and constant magnetic fields. The simultaneous measurement of a spectrum part is achieved with the use of two detectors. They consist of a one inch microchannel plate, an attached phosphor screen, a fiberoptic seal and a linear position sensitive light detector. Ambient atmospheric ions are sampled through a small orifice. The atmospheric air density is reduced in the inlet region of the instrument with a liquid helium cyropump. An octopole HF field is integrated into the ion optics in order to reduce the ion loss.
