AlgSys_Guard
Total Chlorophyll
with Algal Class Differentiation
|
The
AlgSysGuard continuous online fluorometer is a simplified
version of the online Algal
analyser from bbe Moldaenke. The sample is irradiated
by 6 LEDs of different wavelength emmissions, the algal
fluorescence at each wavelength is measured, and the spectra
are mathmatically processed using multiple linear regression
techniques to give the best estimate of the amount of different
algae classes present, together with the total Chlorophyll
a from all algal sources. |
|
Yellow
substances, which also fluoresce are measured with an extra
LED and the results compensated accordingly. Data is not
stored and graphical representation is not available in
the basic version, however it may be connected to a PC runing
the AOA software which will provide graphing and data storage
options.
