Online chromium analysis for industrial water and effluent, with a configuration matched to the measurement you need.
A chromium result is useful only when the measured fraction is clear. The 3S range includes hexavalent chromium and total-chromium configurations. PMA helps bring the required result, the sample and the analytical method into the same specification.
Send the expected concentration, the chromium fraction used in your reporting and details of the sample matrix. Check the proposed method against reference results before using the online trend for operating decisions.
Follow chromium at an agreed sample point and investigate changes in treatment performance.
Review the sample chemistry and expected peaks when selecting a measurement range.
Compare online readings with time-matched samples and the conditions at the abstraction or discharge point.
For chromium(VI), the colour reaction uses diphenylcarbazide. A total-chromium configuration adds an oxidation stage before colour development. The preparation sequence and reagent set must match the required fraction.
The 3S-CL runs batch analyses at a programmable frequency. Automatic calibration, validation and cleaning can be scheduled, and the analyser separates its wet section from the electronics.
Agree the required range, cycle time and plant outputs when specifying the instrument. The manufacturer documentation gives the options and installation requirements for the selected configuration.
Send PMA the sample source, expected concentrations and available laboratory results. Include temperature, pressure, solids and any constituents that may affect the analysis.
We will review sample delivery, filtration or dilution where needed, drainage, reagent storage and service access. Include the required signals and alarm response so the measurement can be used by your operating team.
PMA helps you bring the analyser, sample system and site requirements together. Talk to our team about selection, commissioning, reagent supply and support for your installation.
No. Chromium(VI) and total chromium require different preparation and reagent arrangements. Tell us which fraction you need; do not treat the two results as interchangeable.
Speak to the PMA team about your instruments, reagents or service requirements. Tell us what you need, and we’ll help you find the right next step.
