Sympatec - a pioneer in the field of photon cross-correlation spectroscopy (PCCS) - provides a groundbreaking technology that is based upon dynamic light scattering (DLS) for the analysis of particle size from 0.5 nm to 10,000 nm.
The benefit of PCCS over conventional photon correlation spectroscopy (PCS) is that it accurately measures particle size distributions without the influence of multiple scattered light. As highly concentrated suspensions or emulsions are measured directly, time-consuming sample dilution can be avoided.
With Sympatec’s innovative polarisation-separated backscatter PCCS, NANOPHOX CS takes the proven PCCS to the next level.

Outstanding Performance Features
- Sample concentrations up to a hundred times higher | Evaluate the samples directly in their original concentration without dilution
- Up to ten times faster measurement times | Measurement results in up to under 1 minute
- Enhanced evaluation precision and repeatability
Further PCCS Advantages
- A robust method for research, development, and quality control
- Extension of conventional PCS offers concurrent measurements of particle size and stability in opaque emulsions and suspensions
- Easy sample preparation without undesired dilution series
- Concentration-independent particle characterization by elimination of multiple scattering effects
- Insensitive to sample contamination
- No need for cleanroom conditions
- Direct measurement of agglomeration, stability, and sedimentation of slightly charged (electro-steric stabilized) to uncharged (steric stabilized) particles of turbid samples
- Premature detection of invisible destabilization (micro agglomeration) of suspensions or emulsions
- Highly sensitive to changes in size and measurement of bimodal distributions
- Solid-state measuring technique for in-situ observation of changes in stability or size, e.g., growth and crystallization processes
- Analysis of special effects such as particle-particle interactions and changes in viscosity in high-concentrated samples
- Wide concentration range by PCS and PCCS united
At the push of a button, the PAQXOS software automatically sets all optimal measurement parameters, verifies the measurability of the sample before starting the analysis, and outputs the signal quality for orientation during and after the measurement. The automatic adjustment of the laser intensity and the accurate positioning of the cuvette to optimize the measurement signal are especially user-friendly.
