Algal Online Monitor (AOM)
Algal Online Monitor is a portable and robust device for online detection and continuous monitoring of photosynthetic microorganisms in both natural and artificial water bodies. It detects and discriminates among variety of cyanobacteria, green and brown algae, diatoms, and other microbes. Its ultra-high sensitivity (30 ng Chl/l) allows early detection of very low concentrations of these organisms.
Measured / Calculated Parameters:
- FT : Instantaneous Fluorescence
- QY: Quantum Yield
- OJIP - Fix Area:
Total area above the OJIP fluorescence transient. This parameter correlates with total change of fluorescence signal in OJIP protocol, with total pigment content and hence with cell concentration.
Features:
- Ultra-high sensitive, flow-through monitoring.
- Detection limit 30 ng Chl/l.
- Wide range of detected organisms: cyanobacteria, green and brown algae, diatoms, and other microorganisms.
- Variable excitation colors.
- Turbidity measurement.
- Device modifications for phycoerythrin or phycocyanin (optional).
Applications:
- Water treatment monitoring.
- Early detection of potentially harmful algae blooms.
- Effective control of water treatment chemicals.
