1. If you plan on only taking fluorescence data, the power cable does not need to be attached, nor does the power switch need to be on. This will help save your deuterium lamp for absorbance measurements.
2. In fluorescence measurements, the inner-filter effect is always a consideration. The inner filter effect results in an apparent decrease in emission quantum yield and/or distortion of bandshape as a result of reabsorption of emitted radiation. To avoid this, it is best to perform fluorescence measurements on samples that have an absorbance below 0.1.
