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 variety of cyanobacteria, green and brown algae, diatoms, and other microbes. Its extremely high sensitivity (30 ng Chl/l) allows early detection of very low concentrations of these organisms.
  • 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.
