    FluoroMax-3 v. 3.1 (3 Mar 2006) Optimizing Data Correcting data Introduction Collecting accurate information about the fluorescent or phosphorescent properties of a sample depends upon several factors: • Equipment specifications • Sample characteristics • Timing considerations. To ensure that the spectra collected indicate the actual properties of the sample and not external conditions, data often must be corrected.
