Loading the Sample Pans
Loading Open Pans
After taring the sample pan, load the sample as follows:
NOTE
: This procedure does not apply to sealed aluminum pans. If you are using sealed pan, a different
procedure applies. See below.
1
Place the sample in the sample pan and position the pan on the sample tray in its original position; this
may be done with the tray on or off the instrument. The wire on the bottom of the sample pan, if present,
should align with the groove in the pan recess so that the sample pan can be picked up by the sample
hang-down wire.
NOTE
: Always use brass tweezers to handle the sample pans.
2
Replace the sample tray on the Autosampler, if removed.
You can preweigh the samples prior to the start of the experiment, if desired, in order to obtain a record of
the weight. A preweight is valuable for highly volatile materials. This function is performed before you
start an experiment and the weight is stored within the data file record. See TRIOS software Online Help
for information on this function.
Loading Sealed Pans
Consult TRIOS software Online Help for information on punch calibration and alignment for sealed
aluminum pans. After taring the sample pan and lids, load the sample as follows:
1
Make sure the punch mechanism is correctly positioned and calibrated. This is important for consistently
successful punching of sealed pans. See the figure below.

Follow the procedure to load the sample and seal the sample pans using the sample encapsulating press.
See TRIOS software Online Help for detailed information.
NOTE
: Always use brass tweezers to handle the sample pans.
