For cation analysis, reagent-grade HN[O.sub.3] with molar concentration up to 14 M was added to the sample collected at each site to bring the pH below 1.
With the release of these new drivers, the company adds support for more sample handling accessories, 1C systems with amperometric and conductivity detection and dual-channel systems for combined anion and cation analysis. Metrohm instruments integrate with Empower to control all aspects of a system from a small volume autosampler to detection schemes.

The results of cation analysis contained in the bentonite was conducted by AAS as shown in table 1.
Using a Dionex ICS 2000 system to run anion and cation analysis in 17 min., we have great separation for the following ionic and organic residues (Figure 3):
Recently a polyvinyl alcohol packing material (5-[micro]m YS-506D) containing carboxyl ion exchange groups was developed for cation analysis [5].
Both the software and hardware have been significantly improved, so that with the Advanced IC an even better performance in anion and cation analysis can be achieved--both with and without chemical suppression.
Accuracy of cation analysis was tested through repeated analysis (10% of all samples) of tissue standards obtained from the U.S.
Each of the column temperature zones can be set to a different temperature, so users can perform anion analysis at 30 C and cation analysis in the second channel at 60 C.
Features include high pressure mixing gradients, column switching for dual column anion and cation analysis, and broad analyte concentration ranges.
