Abstract
An electrospray ion source comprises: a needle capillary comprising a spray tip end and an opposite end; a nebulizing gas channel parallel to the needle capillary; an auxiliary gas channel parallel to the needle capillary; a heater parallel to a length of the auxiliary gas channel; a thermally conductive heat transfer member parallel to a length of the needle capillary and disposed between the needle capillary and the heater, said heat transfer member having a first end adjacent to the spray tip end of the needle capillary and a second end opposite to the first end; and a cooled heat sink member in thermal contact with the second end of the heat transfer member.
