Conductive card suitable as a MALDI-TOF target

摘要

Sample presentation device for mass spectrometry, preferably MALDI time-of-flight spectrometry. The sample presentation device of the present invention is composed of a material that has surface electrical conductivity. The surface of the sample presentation device can be rendered electrically conductive in a variety of ways. It is adapted to be removably insertable into a spectrometer, such as a spectrometer tube, for presenting the sample (usually together with a matrix for promoting desorption and ionization of the sample molecules)
