摘要：
The mass spectrum of the L-asparagine monohydrate (C4H8N2O3 center dot H2O) ionized by the 70-eV electron impact has been studied within the = 10-50 amu mass range. A method for determining the most probable atomic composition of the products of fragmentation is suggested. The maximum error of determination of the mass of a fragment ion by this method did not exceed 0.04%. The molecular fragments were analyzed using a commercial MI-1201 mass spectrometer linked to an IBM PC with a digital system of mass spectrum sweep and data acquisition control.
