Microfluidic samples preparation for online liquid analysis with chemical reaction

It is possible to combine our products into more complicated automated systems.

Here, an SPM, an RVM and a custom mixing module are used together to prepare samples for online liquid analysis (with chemical reaction). Several parameters can be measured with this setup, without changing the hardware in any way.

This example measures different parameters in drinking or waste water, such as chlorine, orthophosphate and ammonium. A light source, flow cell, spectrometer and optical fibers are used to allow for a colorimetric analysis.

What is measured in water?

It is required to follow closely the evolution of many parameters in water, so as to reduce the risk of people getting sick. Both drinking and used water are monitored. Below you can find a series of measured parameters depending on the water type.


  • Orthophosphate
  • Nitrate / nitrite
  • Ammonium
  • DCO
  • Total phosphate

Drinking water

  • Orthophosphate
  • Nitrate / nitrite
  • Free and total chlorine
  • Ozone
  • Water hardness

What is my setup?

Requirement component:

  • Computer
  • SPM syringe pump
  • RVM rotary valve
  • Mixer module
  • Flow cell
  • Light source
  • Spectrometer
  • Optical fiber x2
  • Reagents for each parameter
    you want to measure
  • DI water

  • Connectors & tubings




What parameters am I measuring?

In this setup, we measure different drinking water parameters. These are orthophosphate, chlorine and ammonium. It is of course possible to measure other parameters, depending on the reagents that are connected to the system. One must simply check the chemical compatibility between the reagents.


What’s in it for you?

  • One system for multiple parameters
  • Continuous monitoring
  • Low reagent consumption
  • Low carryover
  • Compact design
  • Low maintenance and robust
