Nano Particle Sizing
Precise. Flexible. Reliable.
The DLScat is an enhanced particle size measurement solution, which exploits multiangle dynamic light scattering combined with an intelligent intensity spike filtering algorithm. It determines particle size more accurately and reliably in a large variety of samples, especially those containing contaminants, agglomerates, or polydisperse particles.


Dynamic Light Scattering (DLS) is a fast, convenient, non-invasive optical method for assessing particle sizes in solution, widely used for sample quality validation. The main limitation of existing DLS systems is susceptibility to large particles such as dust or agglomerates, which bias the apparent particle size towards erroneous larger values. Our DLScat offers not only a solution for such contaminated samples but also gives unparalleled control over advanced analysis parameters, allowing you to access the latest capabilities of DLS.

A controlled working environment is required to meet all the specifications mentioned.
* Sample performance metrics are sample-dependent.
** Temperatures down to 0 °C are achievable with external dry-air purging to prevent condensation.
