Particle beam glow discharge mass spectrometry: spectral characteristics of nucleobases.
Use of a particle beam glow discharge (PB-GD) source for mass spectrometric determinations of deoxy- and ribonucleosides and nucleotides is described. Use of this combination of sample introduction and ion source decouples the vaporization and ionization steps, leading to very simple spectral structure. The mass spectra of these compounds are EI-like in nature, with clearly identified molecular...
متن کاملGlow Discharge Mass Spectrometry : Trace Element Determinations in Solid Samples
Glow discharge mass spectrometry (GDMS) is a mature, versatile technique for the direct determination of trace elements in a variety of materials. The technique is an extension of the earliest forms of mass spectrometry. Processes inherent to the glow discharge, namely cathodic sputtering coupled with Penning ionization, yield an ion population from which semi-quantitative results can be direct...
متن کاملRf glow discharge optical emission spectrometry for the analysis of arrays of Ni nanowires in nanoporous alumina and titania membranes
During the last decade, a great variety of nanostructures (nanotubes, nanofibers or nanowires) based on metals, carbons, polymers or semiconductors, have been synthesized following different synthesis procedures by using nanoporous anodic alumina membranes (AAM) as templates [1]. The principal reason for using templates of nanoporous AAM as precursor patterns lies on the possibility to obtain, ...
متن کاملDetection of negative ions in glow discharge mass spectrometry for analysis of solid specimens.
A new method is presented for elemental and molecular analysis of halogen-containing samples by glow discharge time-of-flight mass spectrometry, consisting of detection of negative ions from a pulsed RF glow discharge in argon. Analyte signals are mainly extracted from the afterglow regime of the discharge, where the cross section for electron attachment increases. The formation of negative ion...
متن کاملDifferentiation of Chinese liquors by using ambient glow discharge ionization mass spectrometry.
Chinese liquors are often a very important part of social event in China. Driven by high profit, some illegal traders often use inferior liquors instead of the products with high quality to cheat the customer. Therefore, it is highly required to authenticate Chinese liquors. In this paper a novel method based on ambient glow discharge ionization mass spectrometry has been developed to different...
