BioVigilant Systems, Inc., inventors of the Instantaneous Microbial Detection (IMD) technology, introduces its next-generation IMD. This detection system monitors in real-time environmental air in healthcare, biotechnology and pharmaceutical manufacturing environments.
The IMD-A 300/350 uses optical technology to detect the presence of bacteria, in contrast to traditional culturing or molecular methods, which can take a long time as cultures are being grown.
The system is capable of simultaneously detecting both size and intrinsic fluorescence of airborne particulates. When a particle enters the IMD-A system’s interrogation zone, it intersects the beam of a single laser light source. The scattering of the laser light determines the size of each individual particle. At the same time, the presence or absence of intrinsic fluorescence determines whether the particle is biologic or inert. This single particle analysis capability offers a great sensitivity in the detection of bacteria. Inert and biologic particles are grouped into one of six bins from 0.5 microns to greater than 10 microns to be processed by the software.
Because the system requires no reagents and minimal human operator involvement it is well-suited for continuous monitoring of an environment. While traditional methods periodically check different spots, this machine provides immediate warnings in real-time.
The IMD-A 300 samples 1.15 liters and the larger IMD-A 350 does 28.3 liters of air per minute. It also features a video option that allows simultaneous video capture of the environment being measured for correlation of physical events with detected microbial or particulate excursions. Unique measurement profiles can be customized with specific action and alert parameters for each environmental application.
