A method of operating an instrument which comprises a first and second ion stores, comprising determining whether a target accumulation time for the second ion store is greater than a threshold accumulation time. When the target accumulation time is less than the threshold accumulation time, ions are accumulated within the second ion store using an accumulation time that is based on the target accumulation time. When the target accumulation time is greater than the threshold accumulation time, ions are accumulated within the first ion store using a first accumulation time that is based on a difference between the target accumulation time and the threshold accumulation time, the ions accumulated in the first ion store are passed to the second ion store, and further ions are accumulated within the second ion store using a second accumulation time that is based on the threshold accumulation time.

Ion accumulation control for analytical instrument

A coupling for connecting together vacuum-based analytical systems requiring to be vibrationally isolated, comprising: a tubular connector having a longitudinal axis, the connector comprising a first end for connection to a first analytical system and a flexible portion reducing transmission of vibrations and permitting displacement of the first analytical system in a direction transverse to the longitudinal axis of the connector; and a seal longitudinally separated from the flexible portion, for vacuum sealing between the connector and a second analytical system; wherein the connector contains ion optics for transmitting ions between the first and second analytical systems.
