Abstract
The present invention relates to a spray needle for use in electrospray ionization (ESI) for mass spectrometry. A spray needle is disclosed which is constructed to have an opening along its length such that a sample solution may be more readily introduced or loaded therein. Further, the design of the spray needle of the invention is more durable than the prior art spray needles and may be reusable. Because sample loading is more readily achieved, the spray needle of the invention is appropriate for use with a fully automated system for the analysis of samples.
