Nano particle sizing

More Precise. More Flexible. More Reliable.

DLScat is an enhanced particle size measurement solution, which exploits Multiangle Dynamic Light Scattering (MADLS) 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.

Intelligent intensity spike filtering - advanced technology made easy
Intensity spikes in DLS data arise from contaminants or agglomerates. A single spike can be enough to distort a measurement due to its overwhelming magnitude. It will lead to an erroneous large particle size. DLScat effortlessly eliminates these spikes from the scattered light, thereby recovering the undistorted correlation function of the nanoparticles and ensuring precise measurements.
Immediate consistency checks with up to 6 scattering angles
The most stringent method to confirm that a DLS particle size measurement is correct is to check whether the observed particle size is consistent across multiple scattering angles. That is what makes MADLS so powerful. Existing DLS instruments allow to measure only one angle at a time. Therefore, a multi-angle measurement is tedious and time-consuming, preventing users from performing this valuable consistency check. DLScat measures at up to 6 angles in one shot, enabling effortless consistency checks promptly and routinely.

Dynamic Light Scattering (DLS) - Benefits and Challenges

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. DLScat offers not only a solution for such contaminated samples but also gives you unparalleled control over advanced analysis parameters, allowing you to access the latest capabilities of DLS.
