Malvern and Bio-Rad Collaboration Makes Particle Identification Quicker and Easier

A collaboration between Malvern Instruments and Bio-Rad from Hercules, California has delivered new analytical tools for the rapid identification of unknown particles.

New software to support Malvern’s Morphologi G3-ID, which analyzes particle size, shape and chemical composition, enables the direct comparison of measured Raman spectra with reference spectra in the extensive database of Bio-Rad’s market-leading KnowItAll software.

The result is powerful, robust particle identification capabilities for scientists working in forensic analysis and pharmaceutical/biopharmaceutical development who are trying to determine the nature and origin of unknown particles.

Bio-Rad Laboratories general manager Gregory Banik said: "Over the last few years we’ve witnessed increasing levels of interest in the area of Raman spectroscopy, and we’ve invested heavily in our KnowItAll Raman spectral library.

"We’re pleased that Malvern Instruments has decided to extend access to this valuable resource via the Morphologi G3-ID, an instrument that streamlines the application of Raman within established particle characterization workflows."

Morphologi G3-ID provides fully automated size and shape measurement, capturing images of tens of thousands of particles in a few minutes.

Raman spectroscopy capabilities of the system can be applied to particle populations of interest to provide reliable chemical identification where size and shape alone do not provide sufficient information.

Morphologi product manager Dr Deborah Huck-Jones said: "We at Malvern are delighted that users can now enjoy seamless access to Bio-Rad’s KnowItAll ID Expert, which, alongside a comprehensive database, includes features such as optimized correction technology to enrich spectral searches and maximize use of the database through better matching.

"The embedded spectral intelligence within Bio-Rad’s cutting edge KnowItAll software works extremely well alongside the Morphologi G3-ID to provide a faster and more robust chemical identification."

The latest accessory package for the Morphologi G3-ID also includes the new thin-path wet cell, which enables measurement of suspended samples in their native state, without prior filtration.

This is particularly important for applications in biopharmaceutical development and specifically in subvisible particle identification, where the Morphologi G3-ID offers an orthogonal approach, compared with other dynamic imaging techniques.
