Nano Particle Sizer ANALYSETTE 12 DynaSizer – Particle size measurements between 1 nm and 6 µm with dynamic light scattering!

FRITSCH is also in the field of laser particle sizing always one step ahead. The new Nano Particle Sizer ANALYSETTE 12 DynaSizer uses the Dynamic Light Scattering as a measuring method and therefore enables the measurement of particle size distributions between 1 and 6000 nm.

This new ANALYSETTE 12 DynaSizer extends the FRITSCH-product range in the field of laser particle sizing down to the lower nano range. Fast, accurate and simple! And this with smallest sample quantities and in an extreme wide concentration-range of 0.0003 % up to 40 Vol.-%.

Smallest sample volumes
For measurements with the ANALYSETTE 12 DynaSizer only smallest sample volumes of 50 µl – 5 ml are necessary, which are applied directly onto the optical measuring cell inside the instrument; making disposables such as cuvettes or similar obsolete. Due to the intelligent design, cleaning is as easy as a child’s play.

Measurement of ultra thin layers

Due to the cuvette-free design the thickness of the measurement layer can be variably adjusted. This enables measurements of even extremely thin layers and prevents unwanted multi-scattering effects. It also facilitates the measurement of highly concentrated suspensions as well as in opaque media.

Variable laser power
The power of the laser of the ANALYSETTE 12 DynaSizer is variably adjustable and allows measurements of very dark samples or high particle concentrations of up to 40 Vol.-%.

Particle size distribution and particle concentration

The maximum output power of 65 mW at a wavelength of 658 nm allows the measurement of low particle concentrations. In addition to analysis according to the cumulant method, the powerful Padé-Laplace algorithm is also available for multimodal samples. Combined with the multi-acquisition mode, it is possible to determine medium particle sizes, complete particle size distributions and the polydispersity-index.

Effective, user-friendly and accurate to the nanometer!
