| Definition | An active fluorometer that employs the Single Turnover Active Fluorometry (STAF) method for the quantitative assessment of phytoplankton photosynthesis. It enables evaluation of primary productivity by phytoplankton (PhytoPP) towards greater understanding of the global carbon cycle. LabSTAF represents a significant update to Chelsea's well-established FastOcean Fast Repetition Rate fluorometer (FRRf) and Act2 laboratory systems. It provides 39 fluorescence parameters, in addition to the standard Fluorescent Light Curve (FLC) parameters, plus options for the correction of baseline fluorescence. Includes Windows-based RunSTAF software, enabling a wide variety of experimental setups, manual control or automated operation, plus real-time data analysis. 20 mL maximum sample volume. Excitation waveband central wavelengths: 416, 452 x2, 473, 495, 534, 594, 622 nm. Actinic light source collimated output from 10 to > 1600 umol photons m-2 s-1. Can resolve Fv with an amplitude equivalent to the fluorescence signal generated under 452 nm excitation by 0.001 mg m-3 of chlorophyll. | ||
