This issue may occur if the instrument is not fully purged of the residual enzyme left in the supply lines, especially Trizma. ANKOM recommends flushing the enzyme supply lines with alcohol weekly when enzymes are being used. Further, we recommend...

The enzyme tubing may be clogged. Look at the enzyme tubing from the reservoirs to the Enzyme Pinch Valve and beyond to the manifold. If there is any discoloration or gelled material in the tubing, replace the tubing. Contact ANKOM Technology at...

Refer to TDF Service Procedure E13 Diagnosis (TS001) to diagnose tubing pressure failure.

The following are two possible reasons why enzymes may not be drawn from the reservoir. (1) The silicone tubes may be worn or flattened from use. To inspect the tubing, refer to TDF Service Procedure Tube Replacement (Pinch Valves) (TS005) and...

Do NOT run this instrument without an adequate DRY Nitrogen Supply. The instrument is powered by pneumatics that are not compatible with moisture, commonly found in compressed air. Nitrogen is also recommended as an extra precaution when handling...

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...

Replacement of the dryer completely depends upon how often it is used to dry hydrolysis samples. The filter should be changed when the filter bags do not dry sufficiently after hydrolysis at 110°C for three hours (adding pH paper in the desiccant...

When using the ANKOM Rapid Dryer to dry acid hydrolysis samples, the airflow through the special hydrolysis filter ( Part #: RD2 ) will eventually become too limited and the filter will need to be changed. To check the air filter for proper airflow...

When samples are dried for three hours after hydrolysis, they should be placed in a desiccant pouch ( Part #: X45 ) with a strip of pH paper. When the bags are fully dry, the pH paper will NOT show the presence of acid.

The F57 Filter Bags should not be oven-dried after the acetone treatment. Doing so can release the calendared set (heat and pressure used to flatten) we put on the filtration media from which the bags are made. Simply allow the acetone to completely...

This problem could point to one of four possible issues with the instrument. Investigate in the order below. (1) There could be a hole in the suspect bag position’s fluid line after or within the Pump causing a leak in the back of the instrument. To...

The touchscreen display will give you the option to Retry , Override , or Abort the run. Retry will simply try the delivery again. Override will ignore the fault for the remainder of the run. Abort will stop the run entirely. To analyze the problem...

During a crude fiber or acid detergent procedure, the time frame during which samples are exposed to 100°C solution(s) is extremely important. If the Fiber Analyzer begins a procedure at a temperature higher than 20°C, the instrument will heat the...

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: : Preheat to 200°C; Clear at 300°Cfor 15min; Digest at...
