Real-Time Viable Particle Counter: Discrimination Capability

By Darrick Niccum, senior global product manager-biotechnology, TSI Incorporated

The laser induced fluorescence signatures generated from environmental particles are complex. It is a challenging task to discriminate viable from non-viable particles that have fluorescence characteristics. The BIOTRAK Particle Counter incorporates three discrimination parameters into its viability detection algorithms greatly enhancing its ability to correctly classify viable versus non-viable particles.
