Trace anion determinations in UPW are demonstrated
by direct injection using the Dionex AS-AP autosampler
on a capillary Dionex ICS-5000 IC system Additionally,
this document thoroughly discussed techniques critical
to obtain good chromatography for capillary IC and
techniques critical for trace ion determinations are
discussed in detail. The Dionex AS-AP autosampler,
designed for cleaner and faster introduction of samples,
was discussed. In conclusion, capillary IC provides results
comparable to those of standard and microbore systems,
and provides advantages of continuous operation, lower
flow rates and lower waste generation.
