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 conta minants, 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.
* The size is defined as hydrodynamic diameter. As for all DLS instruments, the maximum range is sample-dependent
** With a sample volume of 50 μL, only the 69°, 90° and 111° geometric angles are measurable. For volumes ranging from 200 μL, all geometric angles are available for measurement.
*** The laser power range is wavelength-dependent. For a 633 nm laser, the range is 3 - 30 mW and can be manually adjusted (30 mW is the maximum value).
Do you need a certain wavelength, want to measure at a specific angle, or include a special analysis algorithm? Our modular DLS system enables us to accommodate your experimental demands. We'd love to learn about your wishes.
