Phytoplankton Analyzer System

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.

Accessory: Temperature Control Unit US-T, Stirring Device WATER-S. A spherical PAR sensor for calibration purposes is already included in the basic set.

Two alternative four wavelength PHYTO-PAM system versions with different emitter detector units are available. Both base on the same central Power-and-Control-Unit PHYTO-C:

  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.

Additionally a Spherical Micro Quantum Sensor US-SQS and a cosine corrected Mini Quantum Sensor US-MQS is available to measure photosynthetically active radiation (PAR) within the cuvette or at the fiberoptics exit to calibrate the light list of the PHYTO-PAM.
