Fluorolog-3 v. 2.2 (31 Jul 2002)
Producing Correction Factors
11-7
Note:
Obtaining emission correction factors for the region between
250 nm and 300 nm is possible. Because the gratings are ex-
tremely inefficient in this range and the standard lamp output is
low, generating these factors is somewhat more involved.
Blank and lamp spectra.
Your spectrum should appear similar to the one pictured above. Its actual
appearance, however, depends on the configuration of your Fluorolog
®
-3
system. The lamp scan was acquired with gratings in the emission spectrometer
blazed in the visible region and an R928P red-sensitive photomultiplier as the
detector. Different gratings or detectors may alter the shape of the lamp
spectrum.
