Laser Particle Sizer with Dynamic Light Scattering
Fritsch have released a new laser particle sizer, the Analysette 12 DynaSizer which uses a dynamic light scattering technique to enable the measurement of particle size distributions between 1 and 6000nm.
It also has an extremely wide concentration range of 0.0003 % to 40 wt %.
When measuring particles only small sample volumes of < 50 µl are necessary - these particles are applied directly to the optical measuring cell inside the instrument; therefore making disposables such as cuvettes obsolete.
When measuring the thickness of a sample the strength of the measurement layer can be variably adjusted. This enables the measurement of extremely thin layers and prevents unwanted multi-scattering effects. It also facilitates the measurement of highly concentrated suspensions as well as in opaque media.
The power of the laser can be adjusted to enable the measurement of very dark samples or high particle concentrations of up to 40 wt %.
