Micro-Flow Imaging

Image-based Particle Analysis for Biopharmaceuticals

Our Micro-Flow Imaging technology (MFI™) gives you more insight into the world of sub-visible particles—way more than just size and count. Because it's image-based, you can add quantifiable morphological parameters to your analysis. You'll be differentiating sub-visible particle populations from each other and classifying them in no time. Plus, MFI has an optic focal length that spans the entire fluidic path, so your sample data is robust and reproducible day in and day out. Add an MFI Bot1 Autosampler anytime to automate the whole process and kick your throughput up a notch. If you're looking for broader, deeper analysis of your biotherapeutic products, MFI is the sub-visible particle analysis tool for you.

How Can Micro-Flow Imaging Help You?

I need to know more about the particles in my sample

Image Based Particle Differentiation

Pharmacopeial agencies are demanding more information on the nature of particles within a pharmaceutical product. Different particle populations present different risks and need different mitigation strategies. The MFI 5000 series can help you differentiate particle populations within your sample with micro-flow imaging to give you insight into the pharmacopeial particle definitions that will support your NDA or regulatory filing.

I need to measure translucent protein aggregates in my sample

Sensitive Detection for Biopharmaceuticals

Protein aggregates can be tough to measure but are important indicators of a pharmaceutical's stability. Micro-flow imaging is more sensitive and can detect more sub-visible particles compared to pharmacopeial methods such as Light Obscuration and manual microscopy. By obtaining the highest data quality on the size and count of sub-visible particles in your sample, micro-flow imaging provides you with the most accurate picture of protein aggregation in your sample.

Micro-Flow Imaging Technology & Applications

How does Micro-Flow Imaging (MFI) work?

Micro-Flow Imaging™ combines the direct imaging capabilities of digital microscopy with the precise control of microfluidics. What does that get you? High resolution images with 85% sampling efficiency, more precise counts and sizing with full morphological detail for all sub-visible particles in your sample and the complete confidence that you can accurately identify every possible type—from protein aggregates to air bubbles.

Diagram of How Micro-Flow Imaging Works When Capturing Images of Samples Using Digital Microscopy

Images of the sample are captured as it passes through the flow cell's sensing zone. Every particle in every image is then analyzed to create a database of particle count, size, transparency and morphology (or shape). And you'll have visual verification on the spot, as images are displayed in real-time. You can also display the results for many samples at once, which makes it easy to monitor stability and comparability.
