DLS training: identifying and securing nanoparticle analysis

The DLS Training meets the needs of industrial professionals who need to measure the size, distribution, and stability of nanometric dispersions with a level of reliability compatible with their R&D, quality, and regulatory requirements. In practice, the interpretation of nanoparticle analysis results can be skewed by sample preparation, concentration, agglomeration, the presence of impurities, the choice of acquisition parameters, or a poor reading of the distributions. Targeted training makes it possible to identify the limitations of the technique, understand the influencing factors, and secure the use of data for complex matrices.

DLS is particularly useful for assessing the hydrodynamic size of particles and tracking the evolution of a dispersion over time. It is used to compare batches, monitor a nanoemulsion, study an agglomeration phenomenon, verify the effect of a reformulation or assess the impact of a process change. The technique is suited to development, optimization and investigation needs when rapid information is required on the dispersed state of a nanoscale system.

The training covers the principles of dynamic light scattering, the concept of hydrodynamic size, size distributions, the polydispersity index, concentration effects, the influence of the dispersing medium and sample preparation precautions. Participants learn to recognize the limitations linked to polydisperse samples, unstable systems or minor populations that are difficult to detect. The goal is to make users autonomous in good measurement practices and in the critical reading of data.

DLS makes full sense when it is placed within a coherent analytical framework. The laboratory relies on complementary technical resources to compare size results with particle morphology, composition, agglomeration state or specific surface area. This cross-disciplinary view helps better understand discrepancies between results, avoid over-interpretation and build robust measurement protocols.

The laboratory supports industrial companies in nanoparticle characterization, nanomaterials research, the study of agglomeration state, stability measurement and the development of tailor-made analytical methods. This expertise is based on practical experience with DLS integrated into a multi-technique approach combining, in particular, SEM-FEG-EDX, laser diffraction particle sizing, BET, XRD, ICP-MS and SP-ICP-MS depending on the issues encountered. The training is designed to connect theoretical principles with real-world production, formulation and quality control cases. For industrial companies operating in demanding environments, this upskilling can be combined with Gmp analysis services or with other specialist pathways such as ICH Q6B Training.

In industry, DLS supports a wide range of issues: raw material control, formulation qualification, understanding instability, release studies, before/after aging comparisons, and assistance with nanoscale classification. The training shows how to position DLS among other characterization tools and when to complement it with morphological observation or chemical analysis. Depending on the participant's objectives, it can be part of a broader training pathway, just like Metallographic Analysis Preparation Training.

Beyond theory, DLS Training provides an analysis method applicable in the industrial laboratory: define the analytical need, choose the measurement conditions, check the consistency of a result, document deviations and decide on a complementary analysis if necessary. The approach is focused on problem solving and making nanoparticle analysis more reliable, with examples inspired by real cases in formulation, raw materials and non-conformities.

The training benefits from a structured laboratory environment, accustomed to the expectations of the cosmetics, pharmaceutical, chemical, medical devices and materials sectors. If needed, it incorporates the issues of declaration, classification or analytical justification related to nanomaterials. This ability to connect the measurement to its usage context is a real asset for industrial companies looking for training that can be directly applied on site or in the laboratory.

Choosing this training means upskilling your teams in a sensitive technique that is often decisive in the assessment of nanometric dispersions. The tailor-made format makes it possible to adapt the content to your matrices, your quality control or development objectives, and the level of maturity of your operators. To go further, it is also possible to align this approach with method development needs, analytical validation, or regulatory support. Request a tailored program, define your use cases, train your teams, make your measurements more reliable, and secure your analytical decisions.
