Particle systems can be complex, but measuring them doesn’t have to be! The Litesizer series from Anton Paar provides particle size analysis in the nanometer range. With the Litesizer 500 you can perform extensive particle analysis using:
- Dynamic Light Scattering (DLS) for particle size and particle size distribution measurements including advanced algorithms for unprecedented performance in the resolution of multimodal samples
- Electrophoretic Light Scattering (ELS) with the Anton Paar patented cmPALS technique for zeta potential measurements in low electric fields and with high reproducibility within significantly shorter measuring times
- Patented focus-dependent scattering intensity measurements for determination of the refractive index. Litesizer 500 is the only DLS-based particle analyzer that is able to perform a straightforward measurement of the refractive index at the same wavelength and temperature of your DLS or ELS experiment.
- Continuous transmittance measurements for instant feedback about your sample, and automatic optimization of measurement parameters like measurement angle, focus position, or measurement duration
- Static Light Scattering (SLS) for molecular mass measurements and determination of the second virial coefficient
A highlight of the Litesizer series is its straightforward and easy-to-use software. You can set up your experiments in a few seconds and produce the analyses and reports you need at the touch of a button. The included one-page workflow of the Kalliope software displays all input parameters, measurement signals, and the results on a single page. In this way all important information is at hand and you are free to concentrate on what your particles are doing instead of trying to figure out how to use the instrument. Kalliope is 21 CFR Part 11 compliant for complete traceability of results.
Two different modules are available in order to perform automated pH-dependent measurements in combination with a dosing system. Further, a number of different cuvettes allow particle size and zeta potential measurements of particles in organic as well as in aqueous solvents and also very low volumes of down to 12 µL.
The unique design of the Ω-shaped capillary in the Omega cuvette enables more stable and reproducible results for ELS measurements due to a straight part of the sample channel which enables a constant electric field at the measurement position.
