Mass‐selected positive ions having kilovolt translational energies can be reversed in direction by applying a large voltage to a collision chamber situated in the second field‐free region of a reversed geometry instrument. It is shown that such repelled positive ions impinge on the earthed plate, situated in front of the chamber, leading to a variety of negative ions. The mass‐to‐charge ratios of these anions have been measured.
