ABSTRACT:
Quantitative determinations by means of mass spectrometry of substances which have hitherto been very difficult to perform are made possible by the employment of the sample holding element of the present invention composed of a porous and gas-permeable aggregate of a skeletal ingredient having refractory and electrical-insulating properties, with a remarkable improvement in sensitivity and accuracy. Determination of mixture samples for their respective components is also effected without any preceding separating step.
