Particle Characterization and Identification: Hound from Unchained Labs

Hound is a complete device that integrates Raman spectroscopy, laser-induced breakdown spectroscopy (LIBS), and microscopy to characterize any particle. Hound enables users to size, count, and ID particles by their elemental or chemical fingerprints.

Hound is equipped with all of these capabilities in one platform and collects the data that users need about their particles, in just a few minutes.
