Abstract (en)

A method of ionising a gas comprises applying an electric potential to one or more ionising elements of a gas ionising device (or ioniser 400), sensing electrical characteristics associated with the gas ionising device, and then using the sensed electrical characteristics to determine which one of at least two different modes of operation to then use when operating the gas ionising device to ionise the gas. The ioniser may thus detect in a start-up phase the type of gas present, which might be nitrogen, air or argon, and automatically select an appropriate mode of operation. The ioniser (400) may be in the form of a static eliminator with pointed electrodes (420).
