Our Technologies are Based on Super-Efficient “Wet Foam Elution”

Sample Prep part 2

 We are particle people.  We consider that our job begins by collecting particles; from air, surfaces, and liquids.  Then, we deliver the particles for detection or identification as the case may be, in the best possible way.  So, to collect the particles we build aerosol inlets, aerosol collectors of different kinds, surface samplers, and water samplers.  For the best possible sample delivery to detectors and identifiers, we build the concentrators (Slide 7).  The concentrator forms the link between the real-world sample volumes and the micro-volumes required by the modern identifiers that we described earlier.

Our Initial Motivation for Sample Concentration

 Sample Prep part 1

We first saw the need for biological sample concentration in the world of Biodefense.  Our background expertise is in biodefense, especially biodefense technology development and testing.  Some of the hardest problems to solve are bioaerosol collection and identification of threats.  We were focusing on those issues when we realized that many of the best bioaerosol collectors either concentrated aerosols into a liquid, or captured the aerosols dry – but transferred the samples to a liquid for analysis and threat identification using the newest hot-rod biological identifiers.  Continue…
