Standard Zeta Features
- Phase Analysis Light ScatteringPat. – utilizing a DSP based PALS technique to measure small doppler shifts in the phase of the light scattered from a suspension allowing you to determine the zeta potential in high ionic strength or high dielectric environments (organics).
- Frequency Analysis Mode – provides a frequency domain zeta measurement. This is very useful in obtaining distribution information on the mean zeta potential value as well as a great tool for providing information on the system alignment in service mode.
- Dip Cell Electrodes – these electrodes can be dipped directly into a disposable cuvette which provides for a uniform electric field between the electrode pair, eliminating the need for the stationary plane determination. These electrodes are made from a rugged palladium tip design which provides a durable dip cell design that has a long-life cycle.
- High Voltage Zeta Potential Cell – measures at higher electric field strengths (up to 250V/cm) in organic solvents.
- Electric Field Strength Compensation – Constant current mode that compensates for fall in the electric field during a sample analysis.
- Polarization Correction – provides a correction for the polarization effects in the Phase Analysis Mode PALS to provide an accurate zeta potential value.

Dynamic light scattering (DLS) measurements have traditionally been performed using laboratory instruments like the Nanoparticles are now standard materials for many industrial products. Like most other processes, the production of nano-particles needs to be measured in order to be controlled. Dynamic light scattering (DLS) measurements have traditionally been performed using laboratory instruments like the Entegris Nicomp system, but the Entegris particle sizing team also has many years of online experience. The Mini DLS builds on these years of experience to develop a flexible and elegant solution that can be adapted to a wide range of nanoparticle manufacturing processes including milling, homogenizing, or self-assembly.

More The Nicomp dynamic light scattering (DLS) system measures size and zeta potential of nano sized particles from 0.3 nm to 10 µm. The backbone of the Nicomp DLS system is a proprietary high resolution multimodal deconvolution algorithm that can resolve close bimodal distributions. More importantly, it can separate the native peak of a distribution from the aggregate tail allowing researchers to determine the size of the native population. This is a critical parameter when trying to develop materials where the native population is directly responsible for the final properties of a product.
The Nicomp DLS instrumentation is engineered using a modular design approach. This allows for semi customization of the instruments based on the customers application needs.
Standard Nicomp Features
- Nicomp high resolution multi modal algorithm.
- Baseline adjust for automatic aggregate compensation.
- Multiple sample cells including a 1 cm cuvette and 6mm culture tubes that are low volume and can be centrifuged to remove contaminates.
- Time history plot provides a visual display of when adequate scattering data is collected to ensure statistically valid results.
- Vesicle Weighting – provides a light scattering correction for analysis of unilamellar vesicles.
Optional Features
- Patented Autodilution – eliminates the need for manual dilution of concentrated samples up to 40% solids. Provides more precise dilutions to the optimal measuring concentration resulting in higher reproducibility. It is the enabling technology for automation; batch autosampler and online measurements.
- Multi-Angle Goniometer – utilizes a precision stepper motor coupled with an optical fiber to provide multi angle sizing from approximately 12 – 175 degrees. Ideal for advanced users with complex distributions in the Mie regime that are looking to focus in on parts of their distribution.
- High Power Laser Diodes – 15 – 100 mW red, 20 – 100 mW green provide adequate scattering for ultra-small particles below 20 nm and low scattering materials avoiding without the need to compromise the measurement by over concentrating the sample which leads to multiple scattering and particle interaction effects.
- Avalanche Photo Diode Detector – provides a high sensitivity detector for low concentration and low scattering samples. Up to 7× gain over a standard photomultiplier tube and when coupled with a higher power laser diode enables accurate sizing information for sub 1 nm particles.
- Low Volume Cells – index matched sample cells for analysis of samples volumes down to 10 microliters. Ideal for expensive protein and macromolecules used in life science applications.
- Autosampler/Online – by incorporating the auto dilution feature in the Nicomp which can handle samples with up to 40% solids, the measurement can be extended into a batch auto sampler platform for automated QC analysis of up to 96 samples
