“…Limits of detection at the pg level were obtained for organobromine compounds when helium was used as the plasma gas [193]. In addition, the authors demonstrated the capability of the system to produce tunable fragmentation of organotin compounds by varying the helium/argon plasmagas ratio [192]. The ratio of elemental tin ions to molecular fragment ions was shown to increase for tetraethyltin as the Ar/He ratio was raised from 0 to 35% Ar.…”

Current and emerging capabilities of plasma-source mass spectrometry (PS-MS) as it is employed for elemental speciation analysis are reviewed. Fundamental concepts and their advantageous aspects, experimental conditions, and analytical performance are described and illustrated by recent examples from the literature. Novel instrumentation, techniques, and strategies for inductively-coupled plasma mass spectrometry (ICP-MS), microwave-induced plasma (MIP) mass spectrometry, glow-discharge (GD) mass spectrometry, and electrospray ionization (ESI), among others, are described. The use of ionization sources that provide tunable ionization, others that can be modulated between different sets of operating conditions, and others used in parallel is also examined.

“…Mass spectra observed were similar to those obtained by conventional electron ionization used in molecular MS, although the relative peak intensities between the two ionization systems were significantly different. On the other hand, Waggoner et al also used an LP/RP-ICP-MS to generate molecular fragmentation spectra of organic tin 15,18 and organobromine compounds. 19 Again, reported spectra obtained by those authors, when used as a detector in gas chromatography (GC), resembled those obtained by EI-MS.…”

Chemical speciation studies are commonly accomplished by resorting to hyphenated analytical techniques, consisting of a powerful chromatographic separation technique coupled to a highly sensitive elemental spectrometric detector. However, in addition to this element-selective information, complementary molecular spectrometric tools are often required for a complete identification of macromolecules. Therefore, there is an increased research effort focused towards the development of integrated instruments to carry out the complete chemical speciation within a sample using a single instrument. An outline of recent developments in plasma-based mass spectrometric instrumentation for such comprehensive chemical speciation studies is here presented and their pros and cons detailed. In this context, the use of complementary techniques operating in parallel after splitting to a single chromatographic separation (dual sources) providing simultaneously elemental and molecular information is critically reviewed. Also, instrumental developments involving the use of stationary plasma sources operated in non-traditional modes (e.g. low pressure and low power) are also discussed. Moreover, the capabilities of tunable plasma-based ionization sources (allowing different ionization processes and, so, quasi-simultaneously providing elemental and molecular information with a single instrument) as a relatively simple and cheap approach are revised.

“…The ionizing capabilities of the glow discharge lies between these two extremes of conventional atomic and molecular ion sources. The number of papers describing the glow discharge as an element‐specific detector for GC is small by comparison to ICP‐MS; however, it does show promise as a ‘tuneable’ plasma source,17 and has been investigated by a number of groups 4–14. The discharge conditions (i.e.…”

Representative organic vapors have been introduced into the flowing afterglow of a low power (<5 W) dc-glow discharge, coupled to a quadrupole mass spectrometer. When a positive bias was applied to the ion sampling orifice, the very surprising result was that molecular mass spectra were obtained with a high sensitivity. When a negative bias was applied to the ion sampling orifice, fragmentation of the analyte was observed with an increase in the extent of ion dissociation as the voltage was increased. The breakdown pattern is compound-specific and would be useful in confirming the identity of an unknown sample. When combined with chromatographic separation, the FFGD-MS technique could be used for chemical speciation studies at the sub-picogram level.
