Getting Started with Spectrum Software . 79
If you change the Resolution (cm−1) in Spectrum software with the slide holder installed in
the sample compartment, a message will be displayed on the Setup Instrument BeamPath
tab, and in the Status Bar, prompting you to insert one of the J-stop cards in the slide holder,
or to remove any external J-stop card (Figure 67).
Figure 69 Setup Instrument BeamPath tab
The J-Stop size selected and the Resolution will be recorded as part of the Instrument
Settings on the History tab of the spectrum. See the Spectrum on-screen help for more
information.
NOTE: For accessories other than the Slide Holder, you cannot insert a J-stop card.
Therefore, increasing the resolution (resolution values below 2 cm
−1
) decreases the
J-Stop Wavenumber, the maximum wavenumber at which you can achieve that
resolution.
