Overcoming the challenge!

Monitoring complex surfactant mixtures

Precisely monitoring complex surfactant mixtures was a significant challenge. Ilmsens' ultra-wideband impedance spectroscopy revolutionized this, enabling:

  • Enhanced product quality
  • Optimized production processes
  • A competitive edge through superior performance and sustainability
  • Innovation in cleaning formulation development.

A leading manufacturer is already leveraging this technology for improved product quality.


The problem

Accurately determining the concentration of surfactants within complex mixtures presents significant analytical challenges. Traditional methods, such as Near-Infrared (NIR) spectroscopy, can encounter difficulties in accurately quantifying non-ionic surfactants due to overlapping spectral signatures, particularly when dealing with mixtures containing multiple surfactant types. This can lead to uncertainties in concentration measurements, hindering the optimization of cleaning processes and potentially impacting product quality and consistency. Furthermore, these traditional methods often require time-consuming sample preparation and analysis, limiting their suitability for real-time process monitoring and adjustments. 

The solution

The solution to this challenge lies in ultra-wideband impedance spectroscopy. By measuring an unprecedentedly wide frequency range, this technique can distinguish between cationic, anionic, amphoteric, and even non-ionic surfactants with low polarity. Each substance has unique electrical properties, resulting in a distinctive electrical signature across the frequency spectrum. By measuring such a broad frequency range, we can capture these individual "fingerprints" of a fluid, enabling the detection of even the smallest differences between liquids.

 

Our partners, who produce complex surfactant mixtures for a variety of applications, have successfully implemented the m:explore.eis system in their quality assurance laboratory. With this system, they have been able to qualitatively and quantitatively determine different non-ionic surfactants within a mixture.


The value

By accurately identifying and quantifying individual surfactant components within complex mixtures, ultra-broadband impedance spectroscopy offers significant advantages. This technology empowers businesses to enhance product quality, optimize production processes, and reduce costs associated with raw material usage and waste. Our partner, a leading manufacturer of cleaning agents, has successfully implemented this technology, resulting in improved product consistency, reduced rework, and enhanced overall process efficiency. This not only strengthens their market position but also contributes to increased customer satisfaction.
