NovaDmax DLS Software

DLS Data Acquisition and Evaluation Software for PN3600 MALS Series

NovaDmax is the novel DLS control and data processing software from Postnova Analytics. The software is used to control a DLS detector instrument and to perform dynamic light scattering (DLS) measurements by analyzing the fluctuations of scattered light of suspended particles. Signal data from a photon detector (APD), which is analyzed and processed by a hardware DLS correlator, can be visualized and recorded.

The software works in parallel and synchronized with Postnova‘s NovaFFF or NovaSEC instrument control software.

This means that individual runs or entire sequences can be loaded into the software and extended with the necessary settings, such as solvent viscosity or refractive index. The integrated solvent database is particularly helpful. This supports the user in searching for the correct parameters such as viscosity at the corresponding cell temperature. Users can also add their own solvents and respective parameters in the database.

The evaluation according to the hydrodynamic radius (R_h) is based on the correlation functions provided by the hardware. Here, the software supports the user with corresponding preset filters and thus finds the best fit for an automatic calculation of the hydrodynamic radius. A manual intervention can be chosen if required. The software also provides the evaluation of the hydrodynamic radius according to first or second order, with the squared correlation coefficients plot supporting data evaluation. Thanks to the optimized evaluation routines, data across the full peak, even down to low concentrations, can be reliably evaluated.
