Anton Paar has launched the Litesizer 500, which determines the size and stability of nanoparticles and submicroparticles in liquids by using light scattering.
Combining key technological advances and clever software has resulted in a high-performance instrument that produces state-of-the-art particle analysis at the touch of a button.
The size and stability of nanoparticles and microparticles is crucial to their function as well as to their processing and transport properties.
The Litesizer 500 provides all the tools for optimising particle systems by revealing how they change with time, pH, temperature and concentration. It determines particle size, zeta potential, and molecular mass by using light scattering technology, in combination with transmittance measurements.
A key highlight of the instrument is its simple software. The user interface is a one-page workflow including input parameters, results and analysis on a single page. Users can set up measurement series in a few seconds, and produce the analysis and report at the touch of abutton.
It is also possible to compare results from different experiments.
“No other light scattering device is so intuitive,” said Jakob Santner, head of characterisation at Anton Paar.
“A subtle but powerful feature of the Litesizer 500 is its ability to measure transmittance. It gives the user instant feedback about their sample, and it allows the device to automatically adjust parameters like the focus position, measurement angle, and measurement duration. The Litesizer 500 really is a smartdevice.”
In addition, highly developed algorithms in the Litesizer’s firmware technology allow users to resolve several different particle sizes in a single suspension.
