For most applications you don’t need to collect a new background
spectrum for each sample spectrum if you haven’t changed the
software parameters. To obtain good results, however, collect a new
background regularly, perhaps once every four hours. (You can
obtain the best results by collecting a new background for each
sample, but this is usually necessary only if you are running
quantitative experiments.)
Whenever you collect a background spectrum for a transmission
experiment, make sure the sample compartment is empty (except for
the transmission sample holder, if you are using it). You can initiate
background data collection at any time by using the Collect
Background button or Collect Background in the Collect menu.
If you are using separate Snap-In™ sample compartment baseplates
for different accessories and sample holders, you can quickly switch
baseplates to install the sample holder. For information about using
Snap-In baseplates, choose Replacing Parts from the Help menu and
then view “Changing the Snap-In baseplate” in “Installing optional
hardware.”
