The SPECTRUM WINDOW can be opened with a right-hand mouse-click on
the 844 icon and then selecting the menu item Spectrum window , or via the
button on the subtab Manual/Detector .
A selection can be made from three different spectra, the absorption
spectrum, intensity spectrum and the zero spectrum. Please note that each
time you click on Absorption , Intensity or Zero the function of the <Update>
button will be triggered.
<Update> The 844 measures the current intensity spectrum and
sends it together with the last zero spectrum to have
been recorded to <IC Net>. The absorption spec-
trum is recalculated from these two spectra.
Absorption The absorption (with the units mAU) is given on the y-
axis as a function of the wavelength (x-axis). The ab-
sorption values are calculated for all measured wave-
lengths and shown a s spectrum. The calculation for-
mula for the absorption value is shown here as an ex-
