Pharmaceutical SEM training: identifying particles and defects

Home • Analytical Chemistry Training • Pharmaceutical SEM Training

Mastering the identification of particles and defects in pharmaceutical products

The presence of particles, residues or surface defects can affect the appearance, perceived quality and investigation of pharmaceutical products. Pharmaceutical SEM training enables teams to understand the principles of observation using a scanning electron microscope, prepare samples appropriately and interpret the images obtained. Participants learn to distinguish morphological anomalies, particulate contamination, coating defects or surface heterogeneity in raw materials, dosage forms, packaging components or associated devices.

Observing morphology and surface defects

The scanning electron microscope provides highly magnified, high-resolution images of sample topography. The training presents the parameters that influence observation, including the choice of imaging mode, magnification, focusing, contrast and precautions related to sample preparation. Participants develop a reproducible method for visualising particles, cracks, inclusions, scratches, coating defects or surface irregularities.

Tailoring exercises to products and investigations

The exercises can be based on samples representative of your challenges, provided they are compatible with the observation conditions. These may include powders, granules, tablets, capsules, coatings, polymer materials, packaging components or isolated particles. The objective is to link the SEM image to an operational question: characterising a particle, comparing a compliant area with an affected area, or documenting an observed defect.

Benefit from application-focused learning

At Filab laboratory, the training focuses on developing participants’ ability to work independently and thoughtfully when faced with microscopic observations. Theoretical concepts are linked to the key stages of an investigation: defining the analytical question, selecting the sample, preparing, observing, comparing and reporting results. Discussions with the trainer make it possible to address the practical challenges encountered by your teams.

SEM training tailored to the challenges of the pharmaceutical industry

Designed for quality, quality control, R&D, production and investigation teams, the training combines the fundamentals of electron microscopy with practical exercises focused on samples and defects encountered in the pharmaceutical environment. The programme is defined around your objectives: observing, comparing, documenting and identifying particles and defects using a methodical approach. It can be supplemented by AFM training to deepen the characterisation of surface properties at the nanoscale.

Complementing observation with EDX elemental analysis

Depending on the selected configuration, the approach may include energy-dispersive X-ray spectroscopy, or EDX, to obtain localised elemental information about a particle or area of interest. Joint interpretation of morphology and detected elements helps guide the identification of an anomaly. For investigations requiring additional characterisation of trace elements, Filab laboratory also offers pharmaceutical ICP analysis.

Using results within a quality-focused approach

Beyond image acquisition, participants learn how to organise observations and draw conclusions proportionate to the available data. The SEM training highlights the technique’s limitations and the situations in which a complementary method is required. This approach promotes clear communication between analytical, quality and production teams during investigations.

Building a programme aligned with your analytical needs

Filab laboratory adapts the level, duration and practical cases to the trainees’ profiles and your industrial context. Complementary courses can also be considered, for example TGA technical training to study the thermal behaviour of materials, or GC-MS pyrolysis training to support the characterisation of organic materials.

Defining your SEM training program

To prepare your project, provide your objectives, the participants’ profiles, the types of samples concerned, and the questions your teams need to answer. Filab laboratory can define a suitable pharmaceutical SEM training program, including theoretical modules, practical exercises, and reporting procedures. Contact Filab laboratory to assess your needs, define the educational scope, and schedule the training.

Frequently asked questions

Why train pharmaceutical teams to identify particles and defects using SEM?

The training helps participants structure the examination of particles and defects: selecting the observation area, preparing the sample, acquiring images, comparing them with a reference sample and interpreting morphological characteristics. It provides the guidance needed to contribute effectively to quality investigations.

What methods and tools are covered during pharmaceutical SEM training?

The training covers the use of SEM for surface imaging and, where appropriate, the principles of EDX analysis to characterise locally present elements. The content is adapted to the participants’ initial level and the use cases defined with your company.

Which samples and defects can be used as training materials?

The training can include representative samples of powders, solid dosage forms, coatings, polymers, packaging components and isolated particles. Filab laboratory checks in advance that the samples are compatible with SEM preparation and observation.

Why choose Filab laboratory to train your teams in SEM?

Filab laboratory offers a program tailored to your teams’ objectives and the challenges encountered with your products. The training focuses on concrete observation situations, an understanding of SEM limitations, and rigorous use of the results.
