Water Sampling with the IMD-W System from azbil BioVigilant:

One Method, Many Applications Purified water has many uses throughout the biologics, pharmaceutical, and medical device industries - from cleaning equipment after manufacturing, to heating and cooling for sterilization and sanitization, to providing the base constituent of life-sustaining therapies. Because of the many uses for highly purified water, there are many ways to use the IMD-W system, an instantaneous microbial detection system for pharmaceutical grade waters.

Using laser-induced fluorescence, the IMD-W system simultaneously measures particle size and determines whether a particle is biologic or inert. This optical design does not require staining or reagents, and incorporates three light scatter signals with advanced software algorithms to detect biologic particles and discriminate non-biologic “interferent” materials which could otherwise be counted as biologics by other systems




• Real-time results without staining or reagents

• Detects particles and determines biologic status simultaneously

• Enhanced interferent discrimination

• Built-in purge and cleaning processes

• Automated system suitability routine

• 21 CFR Part 11 compliant

• Integrated touch screen user interface

• Data may be exported for offline analysis and storage

• Flexible communications interface for networking; can be controlled externally by common industrial control systems (e.g. SCADA, PLC)



• Improved product quality

• Better risk management

• Enhanced process understanding

• Energy savings

• Improved resource allocation and labor efficiencies
