Water Quality Analysis Automation: 4 Real Lab Stories and What They Reveal
Water labs are automating to cut the cost per result, handle difficult real-world samples, protect their people, and keep results compliant and defensible. This article looks at four real lab situations and what each one reveals about how automated water quality analysis actually pays off.
Key takeaways
- Consolidating routine methods onto an automated analyzer lowers the cost per test and shrinks the instrument footprint.
- Working at the microliter scale keeps reagent consumption, waste and kit costs low.
- Automation can handle messy, real-world matrices that resist manual filtering.
- Automating hazardous steps protects analysts and frees them for high-value work.
- Reusable cuvettes cut single-use plastic and waste, a greener routine that also lowers running costs.
- KPM Analytics covers water quality analysis with two complementary platforms: the SmartChem® discrete analyzer and the NexaFlo™ segmented continuous flow analyzer.
Every water lab feels the same squeeze: more samples, too many manual steps, and regulators who expect every result to be robust and defensible. It's easy to talk about automation in the abstract. It's more useful to look at what actually changed for the labs that made the move. Here are four real situations from labs we've worked with, and what each one reveals about what labs are really looking for.
Story 1: Consolidating a lab that was drowning in sequential runs
One lab was processing around 200 samples a day on a sequential technique, ion chromatography, at roughly 15 to 20 minutes per sample. The routine was long, the throughput was capped, and dirty matrices like waste waters and soil or fertilizer extracts kept stressing the instrument itself. Moving the bulk of that workload onto a discrete analyzer changed the math entirely: testing sped up, cost per test dropped, and only the handful of samples below the analyzer's sensitivity still needed the other technique. Fewer instruments, fewer maintenance contracts, less training, a smaller footprint.
What this lab was really after: consolidation. Labs don't want a wall of single-purpose instruments. They want to bring routine methods onto fewer platforms, cut the number of techniques they maintain, and lower the cost of every result they report, without giving up the sensitivity they occasionally need elsewhere. (This lab chose the SmartChem® discrete analyzer from KPM Analytics.)
Story 2: A smarter reagent that cut the cost per result
An Italian customer needed to automate a monochloramine test that traditionally ran one sample per reagent preparation. Working together, we moved the reagent from powder to liquid phase, and a single reagent set went from covering one sample to covering roughly 50, up to 50x more samples per reagent prep, which cut the reagent cost per test and the waste that comes with it.
What this lab was really after: partnership, and a lower cost per result. Beyond the purchase price, what matters is the running cost: reagent consumption, waste, kits. Labs value a supplier willing to adapt a method to their reality and squeeze real cost savings out of the everyday routine, not just automate what already exists. (This lab chose the SmartChem® discrete analyzer from KPM Analytics.)
Story 3: Automating the samples that wouldn't filter
Some samples simply can't be fully filtered. One customer worked with material where micro suspended particles were part of the problem. Rather than fight it, an ultrasonic mixing option keeps those particles in suspension so the system can process them without clogging, letting the lab automate a matrix that would otherwise have stayed stubbornly manual.
What this lab was really after: adaptability. Real samples are messy, and priorities shift as new parameters and matrices appear. Labs want a platform that bends to difficult, real-world chemistry and integrates with their existing workflow, rather than one that only performs on clean, textbook samples. (This lab chose the NexaFlo™ segmented continuous flow analyzer from KPM Analytics.)
Story 4: Protecting analysts from a carcinogen no one has to touch
Nitrate analysis often relies on a cadmium reduction step, and cadmium is a carcinogenic compound. Instead of asking analysts to handle and maintain the coil by hand, the routine is automated: the operator loads the standard solutions, and the system dispenses, washes, primes and reactivates the coil on its own. The analyst never has to touch it.
What this lab was really after: protecting its people. Safety isn't a nice-to-have. Labs want automation that keeps analysts away from hazardous handling and removes the risky, error-prone steps from the daily routine altogether. When the instrument takes on what shouldn't be done by hand, the team is protected, exposure drops, and skilled people are freed for the high-value work only they can do, all while a built-in audit trail and methods validated to ISO, EPA and standard methods keep the lab defensible. (This lab chose the SmartChem® discrete analyzer from KPM Analytics.)
The thread running through all four
None of these labs went looking for a specification sheet. They went looking for outcomes: fewer instruments to manage, a lower cost per result, the flexibility to handle real samples, and automation that frees skilled people from repetitive work while keeping every result defensible.
At KPM Analytics we answer those expectations with two complementary platforms rather than one compromise. The SmartChem® discrete analyzer and the NexaFlo™ segmented continuous flow analyzer share the same software and philosophy, and together they let a lab automate the vast majority of colorimetric water methods, reach very high sensitivity where it's needed, and scale throughput well beyond what manual routines allow. The result isn't just faster measurements. It's fewer instruments to maintain, a lower cost per result, and skilled analysts spending their time on the analysis that actually needs their judgment.

Throughput depends on the platform. A discrete analyzer typically runs 150 to 400 analyses per hour, and the higher-capacity SmartChem® models reach up to 600 tests per hour. Used together, a SmartChem® and a NexaFlo™ cover a combined range of roughly 200 to 600 tests per hour while working at the microliter scale to keep reagent use low.
A discrete analyzer runs many parameters that need no pre-treatment across different matrices in a single run, making it the flexible workhorse of the lab. A segmented continuous flow analyzer automates chemistries that require inline pre-treatment such as digestion or distillation, and reaches very high sensitivity down to sub-ppb levels. The two are complementary rather than competing.
It lowers cost per test by working at the microliter scale to cut reagent consumption and waste, consolidating multiple methods onto fewer instruments, reducing maintenance contracts and training, and automating steps like calibration and out-of-range re-runs so fewer samples are wasted.
Yes. Options such as ultrasonic mixing keep micro suspended particles in suspension so samples that cannot be fully filtered are still processed without clogging, letting labs automate matrices like waste waters and soil or fertilizer extracts.
Yes. The software logs every create, modify and delete action in a full audit trail, enforces user-level access, and applies electronic signatures, in line with 21 CFR Part 11, so results stay defensible under audit.
KPM Analytics offers two complementary platforms: the SmartChem® discrete analyzer for parameters that need no pre-treatment, and the NexaFlo™ segmented continuous flow analyzer for chemistries requiring inline sample preparation and high sensitivity. Both share the same software.
