load the reference pan and place only pans that
actually contain samples in the tray. (This run
capacity also applies to the Autosampler CE with
an RCS used for cooling.)
You should use the same pan type ( e.g .,
crimped, hermetic) and metal ( e.g ., aluminum,
copper) for the reference pan(s) as you do for
your sample pan(s). Thus, if you are using more
than one pan type or metal in one AS run
sequence, you will need to include a corres-
ponding reference pan for each type or metal
used. This will decrease the number of actual
samples in the AS run sequence.
Reuse of Pans
Because thermal analysis experiments can
sometimes deform the pans or cause the sample
material to boil out, we do not recommend that
you reload pans in the Autosampler CE once
they have been unloaded from the DSC cell.
Thus, if you want to run a sample through more
than one thermal method during your AS run
sequence, do one of the following:
1. Run several methods on one sample pan
consecutively. The Autosampler CE does
not unload a pan at the completion of a run if
the next run calls for the same pan.
2. If you prefer not to run consecutive methods
on one sample, prepare several pans contain-
ing the same material.
