An aperture plate assembly for an analytical instrument comprises a first sub-assembly comprising an aperture plate and a second sub-assembly comprising a guide. The first sub-assembly is configured to be attached to the second sub-assembly such that the aperture plate is positioned in a first position relative to the second sub-assembly. The first sub-assembly and the second sub-assembly are configured such that when the first sub-assembly is engaged by the guide, the aperture plate can be moved into the first position and the first sub-assembly can be attached to the second sub-assembly.

Mass spectrometer

A mass spectrometer is disclosed comprising a rotatable isolation valvehaving a curved, spherical, cylindrical or concave portion. At least a portion of an ion guideis positioned so as to extend within a swept volume of the isolation valveenabling the ion guideto be positioned close to a second downstream ion guideand for ions to be transmitted from the firstion guide to the second ion guidewith high ion transmission efficiency.
