Abstract: A nebuliser comprises an outlet aperture and a liquid capillary. A method of operating the nebuliser comprises supplying a gas to the outlet aperture, measuring a flow rate of the gas supplied to the outlet aperture, and determining a position of the liquid capillary relative to the outlet aperture based on the measured flow rate.

Abstract: Disclosed herein is a bench-top time of flight mass spectrometer (100). In embodiments, there is provided a solvent bottle mounting assembly configured so that a user can press a solvent bottle (201) onto the solvent bottle mounting assembly in order to mount the solvent bottle to the mass spectrometer. Other embodiments relate to a vacuum arrangement comprising first and second vacuum chambers with respective first and second vacuum pumps wherein a backing line (1401) for the second vacuum pump is connected to the first vacuum chamber such that the second vacuum pump is backed to the first vacuum chamber. Also disclosed in a method of manufacturing a lens plate or electrode wherein a substrate is chemically etched to reduce a sharp cusp (1803) to provide a smoother edge profile (1804).
