Abstract
A mass spectrometer is disclosed comprising a rotatable isolation valve (1) having a curved, spherical, cylindrical or concave portion. At least a portion of an ion guide (2) is positioned so as to extend within a swept volume of the isolation valve (1) enabling the ion guide (2) to be positioned close to a second downstream ion guide (3) and for ions to be transmitted from the first (2) ion guide to the second ion guide (3) with high ion transmission efficiency.
