Multiple Excitation Wavelength Phytoplankton & Photosynthesis Analyzer

PHYTO-PAM-II COMPACT version features a five-wavelength phytoplankton and photosynthesis analyzer providing deconvolution of up to four differently pigmented groups of algae (green algae, diatoms, cyanobacteria and phycoerythrin containing organisms).
The instrument holds control unit and measuring chamber in a single compact design well suitable for on-deck and field applications.

Due to the outstanding optoelectronic characteristics, five measuring light wavelengths, six actinic light colors and a highly sensitive photomultiplier detector PHYTO-PAM-II features classical PAM analyses, measurements of wavelength-dependent aspects of photosynthesis , fast kinetics measurements with high time resolution to measure O-I1 fluorescence rises as well as evaluation of the functional absorption cross-section of PSII (σPSII).
Therefore PHYTO-PAM-II opens up new aspects in algal research.
