The Z980 AquaPen is a handheld fluorometer that enables rapid and accurate measurement of photosynthetic parameters in suspensions. The measurements are carried out by a submersible optical probe. The AquaPen excels in a very high sensitivity (up to 10 ng Chl/L) and it can measure natural water samples containing low concentrations of phytoplankton. It can be favorably used both for the lab and field applications. The Z980 AquaPen includes the Protocol Update and Software and Data Transfer option with Bluetooth technology.

Applications:

Photosynthesis Research
Photosynthesis Education
Phycology
Limnology
Oceanography
Biotechnology

The Z980 AquaPen measures/calculates four important fluorescence parameters:

FT: Instantaneous chlorophyll fluorescence. Ft is equivalent to Fo if the sample is dark-adapted.
QY: Quantum Yield. QY is a measure of the Photosystem II efficiency. QY is equivalent to Fv/Fm in dark-adapted samples and to Fv'/Fm' in light-adapted samples.
OJIP: Chlorophyll fluorescence transient. OJIP measurement is used as an important biophysical signal that reflects the time course of photosynthesis.
NPQ: Non-photochemical quenching. NPQ indicates thermal dissipation of absorbed light energy during photosynthesis.
LC: Light Curve. LC1 and LC2 protocols serve to describe adaptation of QY to 5 or 6 light levels.
