Notes
1.
Pre-drying time of the samples in the filter bags can be greatly reduced by using a microwave oven. However, microwave ovens
vary in energy output and samples vary in water and fat composition. You will need to experiment with your microwave oven to
determine the proper conditions for use. Contact ANKOM Technology for further information.
2.
Some samples with large amounts of carbohydrates (starches and cellulose) may bind small quantities of solvent and require
additional post drying. To remove bound solvent, dry at 100°C for 1 – 3 hrs or at 125°C for 30 minutes.
