* Pressing the ESC key during spectral acquisition
will cancel the process. Spectral data will not be
memorized.
* The memorize spectrum No. set in the preceding
step will be indicated at SCANNING SPECTRUM
NO.
* Em is effective within the scan range set above.
(g) When the spectral data memorization is completed, the
system returns to the 1
st
monitor screen automatically.
3.4.6 Recorder and spectrum output factors setting
The following items are settable as factors used in recorder
and/or spectrum output.
•
Full scale range of recorder
•
Output speed of recorder
•
Output spectrum data
NOTE
: With an emission spectrum, scattered excitation light,
Raman scattering due to solvent, emission due to
solvent or impurities in it, and second (or third) order
emission may be superimposed on the emission of the
analyte element. Similarly, an excitation spectrum
may be affected by scattered light at the emission
wavelength, by Raman scattering due to solvent, by
emission due to solvent or impurities contained in it,
and by second (or third) order scattered light of the
excitation beam. These factors must be taken into
consideration when selecting the optimum excitation
and emission wavelengths for spectrum acquisition.
Refer to section 2.4 for details.
NOTE
: The excitation and emission spectra output are not
corrected for the wavelength-dependent sensitivity of
the photomultiplier.
The obtained spectra therefore differ from the true
excitation and emission spectra of the analyte element.
This difference is especially noticeable at wavelengths
below 300 nm.
