To properly prepare the IDF & SDF bags for Kjeldahl and Ashing procedures, refer to Section 17 of the TDF Operator’s Manual (Ash Determination) or view the following video: Kjeldahl & Ashing Bag Preparation .
The MoistureStop Desiccant Pouch is a small, airtight zipper bag, utilized for desiccating all of the Filter Bags that are used with ANKOM instrumentation. A single pouch can hold a full run of F57, F58 or XT4 bags at one time. When folded, 6 IDF or...
We have found that it is best to slowly ramp up the digestion temperatures so that foaming in the digestion tubes is minimized. As a result, we would suggest the following times and temperatures: 15 minutes at 150°C, followed by 15 minutes at 250°C...
Refer to the TDF Operator's Manual, sections "IDF/SDF Analysis" and "TDF Analysis."
Some sample types can be difficult to filter, even though the IDF and SDF filter bags have a significantly greater filter surface area than the Gooch crucible. Some samples become gelatinous in an aqueous solution (such as psyllium, chia seeds, or...
Protein determination is performed post the ANKOM TDF Dietary Fiber Analyzer. AOAC methods 991.43, 985.29, and 2001.03 suggest that the Kjeldahl method be used for determining protein content of the residue. AOAC methods 2009.01, 2011.25, 2017.16...
Follow the steps in this instructional video to perform a pH adjustment: TDF Manually Measuring pH in the IDF Digestion . Or, reference section 13.22 of the TDF Operator’s Manual. Note: Measure within the appropriate pH range for your specific...
Refer to the TDF Operator's Manual, sections "IDF/SDF Analysis" and "TDF Analysis."
AOAC 991.43 calls for filtration via a fritted crucible of 40-60 microns with Diatomaceous earth, or equivalent. Particle retention per the method is accomplished by adding diatomaceous earth contained in a fritted crucible. The fine filtration and...
Utilize a transfer pipette to handle this and follow the procedure below: (1) Weigh the pipette and tare the weight. (2) Fill the pipette with a liquid sample. (3) Place the pipette on the balance and record the weight. (4) Pipette out the liquid...
