Transfer a Degassed Sample to an Analysis Port

When degassing on a separate degasser such as a Smart VacPrep, 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 on the analysis port immediately, leave it on the degas port. If it is necessary to remove the sample tube and a Check Seal or TranSeal was not used, insert a rubber stopper into the sample tube.
  1. Allow the sample tube to cool to room temperature (approximately 15 minutes).
 

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 before they have cooled could result in burns.

  1. Carefully remove the heating mantle clip and the heating mantle from the sample tube.
  2. While holding the sample tube, loosen the port connector nut and remove the sample tube from the degas port. If a Check Seal or TranSeal was not inserted prior to degassing, immediately insert a rubber stopper into the sample tube.
  3. Complete the Sample Data Worksheet.
  4. If using a Check Seal, ensure that the Check Seal opener is installed in the analyzer sample port. If a rubber stopper was used, remove the stopper from the sample tube.

  6. Place the connector nut, ferrule, and O-ring onto the sample tube stem.
  1. On the analyzer, loosen the connector nut on the Psat tube and rotate it out of the way.
  2. Position the Dewar cover so that the slot for the Psat tube is on the left.

  4. Dewar cover
  1. Insert the sample tube through one of the holes in the Dewar cover.
  2. Place the sample port nut, ferrule, and O-ring onto the sample tube stem.
  3. Insert the sample tube into the analysis port and ensure it is completely in the port. Securely hand tighten the sample port nut onto the analysis port.
  1. Position the Dewar cover approximately 3/4 in. (19 mm) below the sample port nut.
  2. Slide the Psat tube into the Psat slot in the Dewar cover and retighten the Psat tube connector nut.
