Device for delivery of multiple liquid sample streams to a mass spectrometer |
摘要 |
An electrospray apparatus employing multiple electrospray needles mounted in a circular arrangement sequentially delivers multiple sample streams to a mass spectrometer for analysis. One electrospray device includes an electrospray chamber, a rotatable needle supporting plate, a plurality of electrospray needles mounted on the plate, and a charger for applying a charge to droplets delivered to the electrospray chamber by the needles. Another electrospray device includes an electrospray chamber, a plurality of electrospray needles arranged in a circular arrangement, a charger, and a rotatable member for delivering gas phase ions from one needle at a time to the mass spectrometer. The rotatable electrospray apparatus provides fast repetitive analysis of simultaneously operating chromatography columns or other sample streams with a single mass spectrometer.
