3.H. Sample Analysis
The QuantiFluor™ Fluorometers are capable of measuring samples in two reading modes: Discrete or
Continuous. In Discrete Mode, the instrument measures and averages the fluorescence signal over a 5second interval. In Continuous Mode, the instrument measures and averages the fluorescence signal
over a user-defined interval for each sample measurement. The instrument measures the sample
repeatedly for a user-defined number of samples.
