Sample injection – inline sample preparation
In the beginning there was the syringe – and manual
sample injection is still being used. However, in most
cases the samples are injected automatically into the
ion chromatograph. This starts with a simple peristaltic
pump, which pumps the samples solution to the
injector. Additional components such as valves, filtration
and dialysis cells, neutralization modules etc. then
clear the way for inline sample preparation. The use of
the 800 Dosino as a module for sample transfer and
in particular as a means for exactly measuring out several
solutions and differing volumes, extends these possibilities
even further. Logical and flexible dilution – i.e.
free choice of the dilution factor as well as further dilution
should the result be outside the calibration range
– is only one of the many applications that have been
made feasible with the 800 Dosino.
Eluent preparation
The 845 Eluent Synthesizer eliminates the time-consuming
manual preparation of the eluent and standards
used in ion chromatography. It makes work
easier in the research lab, the analytical lab and in
quality assurance. Compared to the traditional, i.e.
manual preparation of eluents, the fully automated system
guarantees precise mixtures and excellent «batchto-batch»
reproducibility. The 845 Eluent Synthesizer
helps to avoid errors, as it carries out all calculations
automatically, no matter whether in milliliters, mols or
milligrams.
