摘要：

An ion emitter for field ionization and desorption mass spectrometry is presented consisting of a 10-μm Pt wire covered with Pt microneedles formed by cathodic metal deposition from an aqueous 1.5 M sodium hexachloroplatinate solution at 85°C using a galvanic pulse technique. The emitter has good mechanical strength and can be used several times when standard cleaning procedures are applied. Its emission properties are comparable to that of the well known carbon dendrite emitter produced at high temperatures. © 1979, American Chemical Society. All rights reserved.
