A drive unit for driving an acceleration electrode of a mass spectrometer is disclosed. The drive unit includes a power converter comprising a switching element and pulsing circuitry that can form output pulses suitable for driving an acceleration electrode of a mass spectrometer. The drive unit also includes a controller that is configured to synchronise operation of the switching element with the pulsing circuitry.

Mass spectrometer

A method of mass spectrometry is disclosed comprising digitising a signal output from a detector to provide a first digitised signal. A finite impulse response ('FIR') filter, a digital filter or an echo cancellation filter is applied to the first digitised signal in order to reduce the effect of baseline perturbations, echoes or ringing effects. Alternatively, an analogue signal output from a detector is passed to one or more first power splitters or dividers, wherein one or more first transmission lines are attached to one or more ports of one more said first power splitters or dividers in order to reduce the effect of baseline perturbations, echoes or ringing effects.

Echo cancellation for time of flight analogue to digital converter

A method of mass spectrometry is disclosed comprising digitizing a signal output from a detector to provide a first digitized signal. A finite impulse response ('FIR') filter, a digital filter or an echo cancellation filter is applied to the first digitized signal in order to reduce the effect of baseline perturbations, echoes or ringing effects. Alternatively, an analog signal output from a detector is passed to one or more first power splitters or dividers, wherein one or more first transmission lines are attached to one or more ports of one more said first power splitters or dividers in order to reduce the effect of baseline perturbations, echoes or ringing effects.
