About...

Algae Online Monitor (AOM) is a portable and robust device for online detection and continuous monitoring of photosynthetic microorganisms in both natural and artificial water bodies. It detects variety of cyanobacteria, green and brown algae, diatoms, and other microbes.

Key Features

  • 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
  • Device modifications for phycoerythrin, bacteriochlorophyll or phycocyanin (optional)

Algae Online Monitor


Algae Online Monitor (AOM) is a portable and robust device for online detection and continuous monitoring of photosynthetic microorganisms in both natural and artifcial water bodies. It detects variety of cyanobacteria, green and brown algae, diatoms, and other photosynthetic microorganisms. Its high sensitivity (30 ng Chl/l) allows early detection of very low concentrations of these organisms.


Applications


  • Water treatment monitoring
  • Early detection of potentially harmfulalgae blooms
  • Effective control of water treatment chemicals


Measured 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. Special fluorescence protocol:Flash Fluorescence Induction (FFI)


Software


  • Real-time data collection for online measurements
  • Both internal data storage and external communication
  • Data export to Excel for analysis or visualization applications
  • Windows 7, or higher compatible


Versions



AOM 2800


  • 2 × 16 characters LC display


AOM 2700


  • without display
