ABSTRACT:
An electrospray interlace apparatus is disclosed. The apparatus includes an inner needle for transferring a liquid sample to an ionizing region at one end of the needle. A first outer tube surrounds and is spaced apart from the needle to form a cylindrical space through which a flowing liquid may pass. The tube has one end extending beyond the end of the needle to define a mixing volume where the sample and liquid can mix. A second outer tube surrounds the first tube to define a second cylindrical space for flowing a gas past the end of the first tube and needle to focus the electrospray. A voltage is also provided between the tips of the needle and the tubes and an adjacent surface.
