Particle ID and characterization

Hound nails particle identification with its unique spectroscopy combo. Raman fingers the usual suspects like fibers, rubber and proteins. Laser-Induced Breakdown Spectroscopy (LIBS) roughs up the inorganic and metal particles to shake out the elements. Even if your particles are in the sub-vis range, we’ve got the tools to find them too.

Silicone thickness and distribution

Wonky silicone coatings for injectable devices can jam them up or result in excess oil interacting with your drug. Bouncer makes it easy to find out if the coating’s too thick, too thin or good to go. Its quantitative measurements on silicone layer thickness and distribution lets us confirm that you’ve found the sweet spot for your device.

We analyze it all

It doesn’t matter where your particle comes from — inhalers, topical creams, medical devices — we have all bases covered. Unchained Labs provides thorough foreign particulate matter identification, method development and validation for metered-dosed inhalers, dry-powder inhalers and nasal spray formulations. We’ll provide the particle size distribution data you need for topical creams to show that your distribution stays consistent during the drug’s shelf-life. We’ll also develop the methods for routine analyses of catheters, implants and stents, for the isolation, detection and identification of particle contaminants for these devices.

Our toolbox

We’ll use the right tool for the job to find and identify particles or determine the silicone coating of your device. Tell us what you want done or let us help you develop a new method — you’ll get the answers you’re looking for.
