    Fluorolog-3 v. 3.2 (2 May 2008) Optimizing Data Data collection techniques Select the collection method The two basic collection methods are right-angle and front-face. In right-angle detection, primarily for clear solutions, the fluorescence is collected at 90° to the incident exciting beam.
  • Page 85 Fluorolog-3 v. 3.2 (2 May 2008) Optimizing Data Determine the optimum integration time The length of time during which photons are counted and averaged for each data point is called the integration time. An unwanted portion of the signal comes from noise and dark counts (distortion inherent in the signal detector and its electronics when high-voltage is ap- plied).
  • Page 86 Fluorolog-3 v. 3.2 (2 May 2008) Optimizing Data Scan a sample multiple times Scanning a sample more than once and averaging the scans together enhances the S/N. In ½ general, the S/N improves by n , where n is the number of scans.
  • Page 87 Fluorolog-3 v. 3.2 (2 May 2008) Optimizing Data Use the appropriate wavelength increment The increment in a wavelength scan is the spacing, in nm, between adjacent data points. The spacing between the data points affects the resolution of the spectrum, and total time for ac- quisition.
  • Page 88 Fluorolog-3 v. 3.2 (2 May 2008) Optimizing Data Select the appropriate bandpass The bandpass (wavelength spread) affects the resolution of spectra. If the bandpass is too broad, narrow peaks separated by a small change in wavelength may be unresolved. For ex- ample, for two 2-nm peaks 5 nm apart, and a bandpass of 10 nm, one broad peak, instead of two well-defined ones, is visible.
