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.

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...

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...

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: The Q6 Valve (drain valve) is not opening correctly or there is a line blockage between the Q6 valve and the vessel. To best assist you, run a ~10 minute test. Please contact ANKOM with your results. To test: Verify that the Q6...

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...

Refer to XT15 Service Procedure Fault – ETS (X5S016) or Refer to XT10 Service Procedure Fault - ETS (X0S002). Note: Older XT10 or XT15 software may present variations in fault wording. Should technical service be required, please photograph the fault...

This fault display means that at the end of the extraction, the level sensor detected solvent in the vessel (at the end of the run, the vessel should be empty and the sensor should not detect solvent). The instrument has either a Teflon Level Sensor...

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...

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...

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 fault display means the level sensor is indicating a full vessel when the vessel is actually empty. The level sensor has three parts: Glass Tip (visible inside the vessel) SICK Module (blue, found inside the electrical cabinet) Fiber Optic Cable...

There should not be any significant amount of solvent in the vent flask. If the solvent is dripping into the flask during the extraction, there may be a leak in valve Q7, and it may need to be cleaned or replaced. Refer to XT Service Procedure...

Refer to the Fat Extraction Process section of the XT15 Extractor Operator's Manual. Review the subsection titled Sample Preparation Procedure for Crude Fat.

For XT10, see Service Procedure Fault ETS (X0S002). For XT15, see Service Procedure Fault ETS (X5S016).

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...

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...

Refer to XT15 Service Procedure Solvent Drain & Flush (X5S019) linked below.

Refer to XT15 Service Procedure Changing the Solvent (X5S007).

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).

Refer to XT15 Service Procedure Instrument and Components Cleaning (X5S017).

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...

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.

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...

The site glass assembly can be removed and cleaned; however, it is highly recommended to replace the tubing to the site glass after cleaning. Contact ANKOM Technical Service at https://www.ankom.com/contact/technical-services for instructions. The...
