Metrohm ICON 4117 process analyser range

The Metrohm ICON 4117 process analyser range performs photometric absorption measurements in the visible light range. With differential absorbance colorimetry (DAC), the analyser compensates for the colour and turbidity of the sample by measuring both before and after the addition of a colour reagent.

The DAC technique can be used to measure aluminium, ammonia, chlorine, chromium, copper, cyanide, hydrazine, iron, manganese, nickel, nitrate, nitrite, phenol, phosphate, silica and zinc. The photometer module comprises a heated cuvette with 2.4 cm light path and a long-life LED source.

Various parameters can be managed by the software, besides analysis results — low-reagent level alarms, calibration errors and loss of sample are a few examples of alarms that can be logged in the database or sent to a control room for further review by the operator.

Multiple user levels are offered in the software, which are suitable for any operator. Installation is simple. Users connect the power, sample and reagent lines and the analyser is fully operational.
