Abstract
A method of introducing ions into an ion trap and an ion storage apparatus are described. Introduction means are used to introduce first ions into an ion trap through an entrance aperture to the ion trap. An operating condition of the introduction means is adjusted to cause second ions, of different polarity to the first ions to be introduced into the ion trap through the same entrance aperture.
