Abstract
In one aspect, a curtain and orifice plate assembly for use in a mass spectrometry system is disclosed, which comprises a curtain plate including a first printed circuit board (PCB) having an aperture configured for receiving ions generated by an ion source of the mass spectrometry system and at least one gas-flow channel, where said first PCB has at least one metal coating disposed on at least a portion thereof. The assembly further includes an orifice plate coupled to the curtain plate, which includes a PCB providing an orifice that is substantially aligned with the aperture of the curtain plate so that the ions entering the assembly via said aperture of the curtain plate can exit the assembly via said orifice of the orifice plate, where the second PCB has at least one metal coating disposed on at least a portion thereof.
