Fully automated inline eluent preparation on demand
By using the 800 Dosino and the 849 Level Control as the only additional devices, Metrohm`s intelligent ion chromatography (IC) systems – the 850 Professional IC and the Compact IC family – can be easily extended to perform any unattended inline eluent preparation. Fully controlled by MagIC Net™, the 849 Level Control monitors the eluent level while the Dosino performs all dosing and liquid handling tasks.
Consecutive injections of a 250-µg/L standard over approximately 20 days revealed an excellent retention-time stability. After more than 800 consecutive injections, relative standard deviations for anions (F–, Cl–, NO2–, Br–, NO3–, PO43–, SO42–) and cations (Li+ , Na+, NH4+, K+, Ca2+, Mg2+) were smaller than 0.55 and 0.41%, respectively. In the case of a 24-hour sequence, retention-time precision for anions and cations was better than 0.09 and 0.08%, respectively.
The presented inline eluent preparation system increases the retention-time reproducibility and allows the determination of anions and cations over a one-month period without manual eluent preparation.
