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...
This analysis can be performed using the older Kjeldahl Method with filter bags. The automated combustion instruments (Dumas Method) can also be used. With some of the automated instrumentation, it may be difficult to get the entire filter bag into...
First, make sure that your Daisy is not placed under an Air Conditioner or fan. Check your Daisy instrument bulbs, controller, and temperature probe to ensure they are functioning properly. With further questions or concerns, please contact ANKOM...
Refer to the Fat Extraction Process section of the ANKOM XT10 Extractor Operator's Manual. See subsection, Sample Preparation Procedure for Crude Fat.
Yes. For instructions on how to extract liquid samples, view ANKOM XT10 & XT15 Crude (Free) Fat Extraction of Liquid Samples and refer to the Sample Preparation section of the Operator’s Manual.
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...
The XT instrument’s flowmeter should have a flow rate between 4-6 gallons per hour (If chilled coolant is used then the flow rate should be 2-3 gallons per hour). Note that this flow is intermittent and only turns on when cooling is required. When...
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...
Petroleum ether is the most common solvent recommended for use in XT Extractors. Many other solvents will work depending on your objectives but may require upgrades to the method or instrument for them to run effectively. Hexane, for example, will...
This is likely due to a valve that may be "stuck" closed. If the instrument has not been used in a while, it is possible that the solution is simply to clean the valves and clean any debris or buildup that may have settled on the valve piston. To...
There is a leak. The most common cause is a leaky Q1 valve, which would cause cooling water to flow into the vessel during the heating stage. To test: Turn the instrument completely off but keep the water supply on. Check to see if water is running...
When the rotation switch is activated on the Daisy, the jars should continue to rotate until the switch is turned off. Possible Causes: There is not enough friction between the outside surface of the jars and the rollers on the instrument. This is...
Contact ANKOM Technology via e-mail at https://www.ankom.com/contact/technical-services or by calling 1-315-986-8090 for assistance in making this determination. Follow D200 Service Procedure 1 to replace the motor on the Daisy instrument.
The F57 and F58 Filter Bags are ash-free and therefore can be used for ash determination. Refer to the Ashing Procedure Service Procedure (AS034) linked below.
Possible cause: A power surge has occurred. Solution: Reprogram your controller using the controller menu setup in your Operator's Manual
Possible Causes: 1) Sample size is too large. 2) Bags were not acetone rinsed. 3) The rubber baffle spacers fell off. Possible Solutions: 1) Ensure that the procedure is followed completely. 2) Reduce sample size to .025 per procedure. 3) Rinse bags...
The XT10 and XT15 look very similar and have much in common. For example, both perform high temperature, high pressure soxhlet-like extractions on up to 15 samples at a time. The kinetics of the extraction provide an extraction time of no more than...
This can occur with samples that are very low in fat. Moisture left in low-fat samples after extraction is the issue. As AOCS Procedure AM 5-04 indicates, when the Filter Bags are removed from the Extractor, they should be placed in an oven at 100...
For XT10, see Service Procedure Fault ETS (X0S002). For XT15, see Service Procedure Fault ETS (X5S016).
Possible Causes: (1) The dial on the heat sealer may not be turned up high enough. To seal the XT4 Bag, the dial must be set at approximately "6." (2) The heating element is broken. On the sides of the Teflon cover are two shiny metal strips that...

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...
Below is a list of steps to verify that the XT instrument is operating correctly. Always refer to your manual for complete, detailed information. Refer to XT15 Service Procedure Solvent, Vent, and Water Diagram (X5S006) for a four-page diagram that...
When using the Mojonnier mixture of solvents, a black residue may build up on the bottom of the vessel. If this coating becomes too thick, an "Overtemp Fault" "<Enter>" may occur. The black residue can be cleaned using a drill with a long-shafted...
There are three primary reasons for high Crude Fat results. (1) The bag is not completely sealed; therefore the sample gets lost during extraction. (2) A bag picks up surface fat from another sample. (3) Incomplete drying in the pre-extraction phase...
High Fat Samples are defined as any meat sample with a fat content >20% and any plant sample with a fat content >40%. See XT Service Procedure High Fat Sample Handling (XTS014).
To perform an extraction of oilseeds, refer to Oilseed Extractions (FOSFA Equivalent).
Research with high fat samples has given us the following understandings: Some samples with fats that have low melting point triacylglycerides or emulsifiers may encounter fat migration during hydrolysis. To improve fat retention, increase the level...
Some samples with large amounts of carbohydrates (starches and cellulose) may bind small quantities of solvent and require additional post drying. To remove the bound solvent, dry at 100-105° C for one to three hours.
