Characterize all your particles

Hound is the only tool out there that combines microscopy, Raman and Laser-Induced Breakdown Spectroscopy (LIBS) to count, size, and ID particles by their chemical or elemental fingerprints. With all these capabilities packed into one instrument, Hound gathers up all the info you need about your particles in minutes. Get brochure.

Round them up

Hound lets you prep your sample for any type of analysis. Capture big, visible particles by plucking them from solution, or pour the whole sample through a filter round if they’re small. If you want to keep them in suspension, just pipette the sample onto a wet round. No matter what works best for your samples, the gold-coated surfaces catch everything and cut out all the background noise.

Track them down

Once you’ve snagged all your particles, Hound automatically spots them and sizes them up. It uses bright-field or dark-field imaging, so nothing sneaks by — not even tricky translucent particles like proteins. Hound scans the round and reports the size, shape, morphology and fibrosity of everything within minutes.

Identify the unknowns

If you can’t figure out your particle by just size and shape, Hound has extra gear to characterize it. Raman 785 nm is the workhorse laser that can ID most particles. For protein aggregates or particles that have fluorescence, switch to Raman 532 nm. Think you have metals? Blast it with the LIBS laser to identify the particle based on its elements.

Teach Hound new tricks

Raman and LIBS capture the signature from your particles. These unique fingerprints can be saved to a customizable reference database – so the next time you’ll ID it right away. Your images and spectra are stored for reference and reports, and 21 CFR Part 11 software tools help you maintain compliance through data collection and analysis.
