A portable double focusing mass spectrometer is constructed for gas analyses. The apparatus consists of a simple homogeneous magnet having rectangular pole pieces(rm=15cm, φ m=30°, ε1=ε2=15°), a double quadrupole lens and a parallel plate condenser. The total ion path length is40cm, and the weight of the magnet is only8.5kg. Adjustment of the double focusing condition is achieved by changing the electric lenses without any mechanical adjustment. The maximum resolving power obtained is600with a10%valley separation with a10μm ion source slit for an accelerating voltage of1.9kV. Transmission rate is obtained at13% for a5mm magnet gap, and a mass range of360is realized.
