Moens et al.124 demonstrated that ion-molecule reactions in a dynamic reaction cell (DRC) of ICP-QMS allow the 87Rb+/87Sr+ isobaric interference to be eliminated. A special ion-molecular reaction in a collision cell was studied in order to avoid this isobaric interference of atomic ions... 

The complementary use of LC-ESI-ToF-MS and hyphenated ICP-MS with dynamic reaction cell (DRC) for the characterization of native and recombinant copper proteins (of molar mass range 10-20kDa) has been investigated by Hann et al.67 Size exclusion chromatography (SEC) and ion chromatography (IC) were implemented as separation techniques for hyphenated ICP-MS of intact Cu containing proteins. 

A new generation of quaclrupole-based ICP-MS instruments offer an ion focusing and molecular ion destruction device named hexapole, collision cell or dynamic reaction cell depending on the manufacturer [17]. This device increases the transmission and destroys molecular ions with varying efficiency. An example of molecular ions and their impact on the analysis of bromine is shown in Fig. 3-... 

Recently, Tanner et al. [118-120] described a quadrupole reaction cell they have termed a dynamic reaction cell (DRC) used with a quadrupole mass spectrometer (Fig. 3.12b). Reactive gases, such as NH3, H2, O, and H20, were investigated. Charge transfer or proton transfer reactions could be used to advan-...

Analyzer Q = quadrupole, CC = collision cell, DRC = dynamic reaction cell, MC = multicollector, SF = sector field. Analytical details CV = cold vapor, ETV = electro-thermal vaporization, FI = flow injection, HG = hydride generation, ID = isotope dilution, LA = laser ablation, UN = ultrasonic nebulization. Sample introduction in liquid or slurry (si) form. 

Other elements were measured by a Perkin-Elmer SCIEX ELAN 6100 DRCII Inductively Coupled Plasma Mass Spectrometry (ICP-MS) instrument equipped with a cyclonic spray chamber, a concentric nebulizer and a dynamic reaction cell (DRC). In the vented (standard) mode, no reaction gas is present in the cell and the instrument shows the typical characteristics of a quadrupole-based ICP-MS apparatus. When the gas is introduced into the cell an ion-molecule reaction takes place that can be tailored so as to eliminate spectroscopic interferences. Experimental conditions are summarized in Table 10.2.

To quantify the trace elements of interest plasma-based techniques were used, namely (i) ICP-AES using an Optima 3100 instrument (Perkin-Elmer, Norwalk, CT, USA) equipped with a cross-flow nebulizer and a Ryton Scott spray chamber (ii) Dynamic Reaction Cell (DRC) Q-ICP-MS using an Elan 6100 spectrometer (PerkinElmer, Norwalk, CT, USA) equipped with a quartz cross-flow Meinhard nebulizer and a cyclonic spray chamber (iii) SF-ICP-MS using an Elementl (ThermoElectron, Bremen, Germany) with a pneumatic nebulizer and a Ryton Scott spray chamber.
