Why are my Crude Fat results low?

Crude Fat results could be low for any of the following reasons: 

• The extraction was not run long enough.
• The sample was not post-extraction dried enough.
• Fat migrated from a bag during the pre-dry step.
• Desiccant was either not used or incorrectly used during the post-dry phase.
• The water was not turned on or the flow meter was turned down.
• There was too much sample in the bags or too many bags in the instrument.
