Follow nitrate changes in source water, rivers and treatment processes with automated analysis at your monitoring point.
A periodic collected sample describes one moment. Nitrate concentrations can also change with rainfall, catchment inputs, abstraction and treatment operations. A frequent on-site record helps your team see the timing and pattern of those changes.
Aquamonitrix NOx-monitrix Mobile automates nitrate analysis using ion chromatography followed by UV detection. It also reports nitrite separately, adding useful context without combining the two results into a single nitrogen value.
Use the data to investigate your site, compare monitoring points and guide follow-up sampling. PMA can help you specify a representative sample arrangement and a practical deployment.
Follow nitrate trends through changing flow and weather conditions. Compare upstream and downstream points, and relate events to land use and confirmatory sampling.
A result at one point describes that sample; identifying a source requires wider investigation.
Review nitrate variation in boreholes, surface-water sources and blended supplies. Place the measurement where it informs your abstraction or treatment decision.
Confirm the ion or nitrogen reporting basis before comparing datasets.
Observe nitrate entering or leaving a treatment stage, or assess treated water for a reuse application. Interpret the trend alongside flow, process conditions and other measurements.
Automation provides information; control changes need an agreed operating strategy.
The analyser needs a sample that represents the monitoring point. Assess the inlet position, seasonal water levels, suspended material, sample-line length and the delay between collection and analysis.
For a remote site, plan secure mounting, service access, suitable temperature protection and a realistic power budget. Solar and battery sizing depends on the analytical schedule, communications and local daylight.
Choose the recording and alert arrangements your team will use. Datamonitrix can provide remote data and instrument status when configured; a control-system installation can use the specified communications interface.
Keep a documented routine for inlet inspection, cleaning, eluent replenishment and checks against independent samples. Field automation should make that routine more informed and practical.
The freshwater and wastewater range is 0.6–500 mg/L as NO3−. At 35 ppt salinity, the published lower limit is 1.0 mg/L as nitrate.
These values are expressed as the nitrate ion, not nitrate-nitrogen. Make that distinction explicit in reports and system configuration.
Mobile can analyse as frequently as every 15 minutes. Chromatographic separation precedes UV detection and delivers separate nitrate and nitrite concentrations.
Account for the sample journey and analysis cycle when comparing results with rainfall, flows or process events.
Technical basis: NOx-monitrix Mobile manufacturer specification. Confirm the exact model and sample suitability with PMA.
Aquamonitrix describes a West Cork river-basin deployment for Ireland’s Local Authority Waters Programme. Monitoring began in 2021, with a solar-powered upstream installation and a mains-powered downstream installation.
The paired record was used to investigate nutrient changes in the catchment. A short-lived nitrite event prompted follow-up investigation and collected-sample checks, illustrating why the separate nitrite result can be useful alongside nitrate.
This is a manufacturer-reported historical case, rather than a claim about a PMA customer installation. It provides a practical example of using frequent measurements within a broader investigation.
Tell PMA the monitoring purpose and location, expected nitrate concentrations and reporting units, water matrix, salinity, solids and temperature. Include access, available power, sample-line route and data requirements.
We can then review the configuration, sampling frequency and maintenance arrangements with you before installation.
They use different reporting bases. Nitrate is the concentration of the complete nitrate ion; nitrate-nitrogen expresses the nitrogen portion. Record the basis and use the correct conversion before comparing values.
No. Choose the frequency around the changes you need to follow, available power, consumable use and the practical operating routine. Confirm the configuration with PMA.
A concentration record helps reveal changes and guide investigation. Source attribution also needs information such as flow, monitoring locations, land use and confirmatory sampling; the analyser alone does not identify the source.
