Online ion chromatography need no longer be the preserve of electronic chip makers and nuclear power stations thanks to this new low-cost instrument
Traditionally, on-line ion chromatography has been only for the rich, as only those with big expense budgets could afford to buy and run them.
Now, however, Metrohm has launched the 821 compact on-line IC, offering affordable on-line ion chromatography.
At less than half the purchase and maintenance cost of its competitors, it makes the technology available to many who may previously have never considered the technique.
The 821 can make sequential determination of anions or cations from up to ten different sample flows.
It contains an industrial PC, interruption-free power supply with approx 45-minute autonomy, and modem for remote maintenance.
It also includes software with control cards for measurement results, calibrations, and performance checks, as well as for controlling the analysis and the ten channel sampling valve.
The instrument is supplied with a removable trolley.
It can also be prepared for wall mounting. Alarm signals warn central control that the process has strayed outside programmed parameters.
The system requires only a monthly maintenance schedule.
It is easy to set up and use, and can be operated by non-skilled chemists with basic training.
