These parameters are used to identify the presence and the amount of specific molecules in a medium. Modern fluorometers are . Measure the intensity of the fluorescent signal from dyes attached to biological molecules as well as naturally fluorescent molecules based on signature excitation (Ex) and emission (Em) wavelengths. A fluorescence spectrophotometer (or fluorometer , fluorospectrometer, or fluorescence spectrometer) measures the fluorescent light emitted from a sample at different wavelengths, after illumination with a xenon flash lamp.
PSI PAM fluorometers measure a number of photosynthetic parameters, such as, fast OJIP transient capture, pulse amplitude modulation (PAM), QA reoxidation, state transitions, quenching parameters, photochemical yields, or determination of the effective antenna size in Photosystem II.
Single-tube and microplate fluorometers with simple navigation are preprogrammed with our assays to give you superior. Related lesson plan Examining Marine Green Algal Cells What is this sensor?
