Type of Instrument Phytoplankton Analyzer
The instrument measures: Chlorophyll Fluorescence

PHYTO-PAM instruments facilitate measurements of mixed algae populations for distinct analysis of their photosynthetic performance and light-adaptation states. Green algae, diatoms, cyanobacteria and with PHYTO-PAM-II also phycoerythrin containing organisms like cryptophytes can be analyzed down to a concentration of 0.1 µg Chl/l as it can be found in natural surface waters or coastal seawater.

Miniature photomultiplier detectors enable extremely sensitive fluorescence detection for standard PAM measurements like saturation pulse analysis, light curves and induction curves. The PHYTO-PAM-II COMPACT version additionally features a fast kinetics mode for evaluation of OI1 and the absorption cross section of PSII (σPSII).

The new COMPACT version PHYTO-PAM-II features five measuring light wavelength for simultaneous differential measurement of four algae groups, six variable actinic light colors for standard PAM measurements and assessment of functional absorption cross-section of PSII in just one compact instrument.

MODULAR version with separate LED-array cones for measuring light and actinic illumination, featuring a 10 x 10 mm cuvette for homogeneous illumination.
Available accessories are the miniature stirrer PHYTO-MS and the Temperature Control Unit US-T .

FIBER version is using a focusing fiber optic for periphyton and microphytobenthos measurements
