Abstract
A Faraday Cup charged-particle detector for use in an isotopic ratio mass spectrometer is provided with a charged-particle collector substrate being at least partially composed of carbon produced by burning wood or other grained or cellular organic material so that the substrate surface has an open cellular structure and wherein the cells are of elongated tubular form. The detector is economic to manufacture, reliable and has an increased lifetime.
