Possible Causes: When the start button is pushed, the computer tells the appropriate valve to open and allow flow from the cubitainer into the vessel. If the liquid is manually poured into the vessel before the computer communicates with the...

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...

This may be the result of one of the IDF or SDF valves being stuck in a closed or partially closed position. Using the Diagnostics screen select Valve Test and look for IDF Inlet, SDF Inlet, and Waste buttons. Run a brief test using the screen to...

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

An E11 fault is the result of the high-pressure sensor reading input pressure below 35 psi. N2 input pressure is always monitored and the fault could occur at any point during a run. The fault will interrupt the run and wait for the operator to...

The Silicone Pump Tubing ( Part #: TDF68) should be changed when the instrument prompts the user with an E13 warning for weak pump tubes. The pump tubes typically last 6 months under normal use. Heavy usage may necessitate a more abbreviated...

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 testing...

Possible Causes: (1) The packing nut may be too tight. For proper tightening instructions, refer to Service Procedure Agitator Packing Maintenance and Nut Adjustment (AS001). (2) The packing assembly may have corrosive buildup. If periodic...

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...

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 which contains a desiccant packet. It is utilized to desiccate while cooling all of the Filter Bags that are used with ANKOM instrumentation. A single pouch can hold a full run of F57...

Negative results can occur when: Very low fat content samples are not dried properly after solvent extraction. Refer to AOCS AM 5-04 for proper technique. After solvent extraction, filter bags must be dried in an oven at 100 - 105°C for 15-30 minutes...

Refer to the Fat Extraction Process section of the ANKOM XT10 Extractor Operator's Manual. See subsection, Sample Preparation Procedure for Crude Fat.

Yes, it is possible to extract liquid samples in an XT Extractor. Refer to the ANKOMXT15 Extractor Operator's Manual (Section: Sample Preparation) for details on how to weigh liquid samples into the filter bags.

Yes, all samples should be treated the same during the drying process. The biggest and most common cause of artificially high crude fat results is incomplete drying in the pre-extraction phase. Because our technique uses the indirect method of...

Possible Causes: (1) The vent tube or drain tube is blocked. The blockage is caused by water trapped in the line. It is very important that the vent and drain tubes run downhill and are not submerged in water. If the vent tube is blocked, a vacuum is...

Possible Causes: (1) The controller needs to be reset. Refer to Service Procedure Controller Temp Menu Setup (AS015) to determine if menu settings are incorrect and, if so, make the appropriate changes. (2) The RTD may need to be replaced. Contact...

The Overtemp message happens when the ANKOM HCl Instrument is heating but there is no solution in the vessel. The quartz heaters will heat the vessel and the ETS (Emergency Temperature Switches) will trip. Possible Causes: The instrument was not...

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 the lid is raised, some residual acid may flow onto the hinges and the handle. Over time, corrosion will occur if this happens. When lifting the lid after a run, it is recommended that the lid be wiped off with a paper towel to prevent dripping...

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...
