STEP-Technology® - Measure the Stability of Colloidal Dispersions, Emulsions, and Suspensions

Directly

Single Particle Light-Scattering Technology® - Count and Size Every Suspension Particle and Emulsion Droplet

Accurately

Using the patented STEP-Technology®, you can directly measure the stability of your colloidal dispersion, emulsion, and suspension across your whole sample (ISO Technical Report ISO/TR 13097:2013). No sample dilution is required.

With the patented Single Particle Light-Scattering Technology® (SPLS), you can accurately count and size all dispersed particles in liquids. Its special hydrodynamic focusing and optical setup gives you unprecedented dynamic range and accuracy in the nanometer and micron-size particle counting and sizing range - one particle at a time.

Colloidal Dispersion Characterization

You can analyze all colloidal stability and instability processes, such as creaming, sedimentation, aggregation, flocculation, coalescence, precipitation, phase inversion, and Ostwald ripening—no dilution is required.

You can do so because the STEP-Technology® is a “first principle” measurement technique that instantaneously captures your formulation’s dispersion state across the entire sample.

In philosophy and science, a first principle is a basic proposition or assumption that cannot be deduced from any other proposition or assumption…….

….a calculation is said to be from first principles, or ab initio, if it starts directly at the level of established laws of physics and does not make assumptions such as empirical model and fitting parameters

Measuring Colloidal Dispersion Stability

The distinction between first and non-first principle techniques is not merely academic. It has real-world applicability and significance.

First: choosing a first principle technique to measure colloidal dispersion stability ensures the results are accurate and applicable to real-world product performance.

Second: the ability to analyze your sample in its original state - no dilution required. Just place your formulation in the instrument and press start.

Third: the capacity to perform product shelf-life calculations and predictions.

The STEP-Technology® takes these advantages one step further by allowing you to analyze not just one point in your sample but your entire sample from top to bottom.

So you can characterize and understand any colloid dispersion-based product and application successfully, we integrated the STEP-Technology® into different analytical platforms.
