Preparing Samples

Transferring the Degassed Sample to the Analysis Port

The sample tube must be removed from the degas port, weighed and then installed onto the
analysis port for analysis.
If the sample tube is not mounted to the analysis port immediately, either leave it on
the degas port or remove it and insert the rubber stopper (unless you are using a seal
frit) into the sample tube opening.
1. Allow the sample tube to cool.
Do not touch the sample tube or the heating mantle until they have reached room
temperature. Touching the sample tube, heating mantle, or heating mantle clip
could result in burns.
2. Carefully remove the heating mantle clip and the heating mantle from the sample tube and
allow the sample tube to cool to room temperature (approximately fifteen minutes).
3. While holding the sample tube, loosen the port connector nut and remove the sample tube
from the degas port. If you are not using a seal frit, insert a stopper immediately. Remove
the connector nut, ferrule, and O-ring from sample tube stem.
4. Weigh the sample tube set. Enter the weight on the Sample Data Worksheet as Mass of
sample tube plus sample (After Degas).
5. Subtract the Mass of empty sample tube (Before Degas) from the Mass of sample tube plus
sample (After Degas) to determine the mass of the sample. Record this value as the Mass
of sample (After Degas).
6. Slide an isothermal jacket down over the sample tube stem until it touches the sample tube
bulb.
7. Place the connector nut, ferrule, and O-ring onto the sample tube stem.
8. Remove the stopper and immediately attach the sample tube to the analysis port, pushing
it fully up into the port. Secure it in place by screwing the connector nut onto the analysis
port connector; hand-tighten the connector nut.
You do not have to remove the seal frit if used.
