Sporian Microsystems, a developer of sensors and sensor systems based in Lafayette, Colo., has shipped first article units for a new in-line biological sensor based on its patented technology. The system, which could work in combination with water purification and testing systems, runs autonomously with LEDs to indicate pathogen concentration. It includes a USB interface and attaches to a personal computer or netbook for logging sensor data for trend analysis. Initially to include sensing capabilities for Escherichia coli and Enterococcus faecalis, the system will be evaluated by the US Environmental Protection Agency and the US Army Corps of Engineers.
