“…A wide variety of methods have been used to determine arsenic such as hydride generation atomic absorption spectrometry, inductively coupled plasma atomic emmision spectrometry, and neutron activation analysis (26)(27)(28)(29)(30). All of these methods require expensive instrumentation and are essentially sensitive to total arsenic.…”

A critical evaluation of a highly sensitive and specific liquid chromatography amperometric detection method (wall jet cell) for the determination of arsenic has been undertaken with platinum disk electrodes of variable size. The limit of detection is considerably tower with platinum disk electrodes of conventional size (millimeter radius) than Is the case with microelectrodes (radius in micrometer range) because of a more favorable signal to noise ratio Thus, the determination of arsenic is readily achieved In a bottled mineral water sample with a conventional size electrode, whereas the arsenic levels are too tow to be detected precisely with a microelectrode. However, with respect to the desirable properties of a tower dependence on flow rate and a shorter time taken to achieve a stable baseline, and In cases where sensitivity is not a problem, the microelectrode method is advantageous. The method for detection of arsenic Involves a surface-based oxidation process In which As(III) is converted to As(V). This work suggests that advantages and disadvantages offered by using microelectrodes as an alternative to conventionally sized electrodes are critically dependent on the mechanism of the electrode process.

Low and high resolution inductively coupled plasma mass spectrometry (ICP-MS) coupled with ion chromatography (IC) has been investigated for speciation of Cr(III) and Cr(VI). In particular, the interference of ArC + formed by the carbon in a sample on the simultaneous determination of Cr(III) and Cr(VI) has been studied. In chemical speciation, this study shows that quadrupole type ICP-MS with low resolution has a limitation of simultaneous determination of chromium species if the sample contains the carbon elements. The interference problems can be solved by high resolution ICP-MS.

“…Electrochemical detection has been successfully applied to the separation of electroactive species such as cyanide, sulfide, iodide, and bromide (6), while the pulsed amperometric detector, described by Johnson and co-workers, permits detection of aldehydes, alcohols, and carbohydrates (7)(8)(9)(10). Element-selective detection such as atomic absorption (11), direct-current plasma (12), and inductively coupled plasma (ICP) spectroscopy ( 13) have also been used to attain selective and sensitive detection in ion chromatography.…”

The Ion spray liquid chromatography/mass spectrometry (LC/MS) Interface Is coupled via a postsuppressor split with an Ion chromatography (IC) system. The micromembrane suppressor selectively removes over 99.9% of the ion-pair agents required for Ion chromatography from the eluent. The resulting solution consists of analyte, organic modifier, and water, which Is compatible with Ion evaporation mass spectrometry. A flow rate of 0.8 or 1.0 mL/min from the column was split after suppression such that approximately 10-20 /zL/mln was directed to the Ion spray LC/MS Interface, which was coupled to an atmospheric pressure Ionization (API) mass spectrometer. This system provided a convenient way to effect Isocratic and gradient separations of organic Ions under chromatographic conditions Incompatible with most forms of mass spectrometrlc Ionization. This work describes the separation and positive ion detection of quaternary ammonium drugs and tetraalkylammonlum compounds of Industrial Importance using both single and tandem mass spectrometrlc detection (e.g., IC/MS and IC/MS/MS). The former easily provided the molecular weights of these compounds while the latter gave some structural Information. The limit of detection (LCD) of 40 pg Injected on-column for tetrapropylammonlum cation Is a factor of 10 better than that obtained with the conventional IC conductivity detector. The separation, detection, and Identification of some alkyl sulfates and sulfonates are also shown with negative Ion detection.Again, IC/MS readily produced the molecular weights of these compounds while IC/MS/MS provided some structural Information.
