6. Tare the weight of the empty filter bag and the holder together.
7. Add 0.45 – 0.50g of sample to the filter bag. Keep all particles away from the sealing area
of the filter bag.
8. Record the weight of the sample (W
2
).
9. Seal the filter bag within 4mm of its open end. Keep the sealer arm down for 2 – 3 seconds after the red sealer light
turns off (to cool the seal). The seal can be seen as a solid melted stripe along the top edge of the filter bag. If the
seal is not strong, re-seal the bag.
10. To eliminate sample clumping, spread the sample out uniformly within the filter bag by shaking and flicking the bag.
11. Repeat steps 5 – 10 for all filter bags that will be used in the Analyzer. (Up to 24 bags can be processed during one
procedure with one of the bags being a blank.)

3. Put the top on the container.
4. Shake the container 10 times and allow bags to soak for 10 minutes.
5. Pour out and dispose of the acetone.
6. Execute steps 1 through 5 a total of two times.
