MiniTEM - designed for sub-visible particle characterization

New regulatory requirements demand root cause analysis to understand the impact of changes during process and product development.

Nanoparticles like viruses, VLP particles and adjuvants in the 0.05-0,1 µm size range need to be quantitated, size analyzed and characterized.

MiniTEMTM transmission electron microscope is specifically designed to characterise nano-particles. As a compact low-voltage system, it runs in any laboratory setting. All you need is a standard wall socket. MiniTEMTM includes all the components you expect to find in a quality electron microscope.

Analyses

Morphology

Morphology analysis based on automated classification.

Size distribution

MiniTEM can separate particle types based on morphological appearance and provides shape and size distributions of the particles of interest.

Aggregates

Using direct imaging methods helps to assess the level of particle aggregation in a sample. Direct visualization allows differentiation of free versus aggregated particles.

Surface structure

Changes or choices at different steps during process and product development can affect particle surface properties critical for final product efficacy.

Capabilities

Acquisition

Automated to reduce manual operating time.

Classification

Automated based on structural characteristics.

Detection

Integrated detection of different macro-structures enables per particle analysis.

Measurements

Visualized live and easily shared in reports.

Traceability and report generation

In addition to the features in MiniTEM you can also use Vironova Analyzer Software (VAS) for your aquired images to get full traceability of all data plus an automated report generator function.
