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...
Possible Causes: The power cord is not plugged into the unit or power source. The main power switch is not turned on. One of the system circuit breakers (fuses) needs to be replaced. Refer to Service Procedure Fuse Replacement (AS025).
Refer to the TDF Operator's Manual, sections "IDF/SDF Analysis" and "TDF Analysis."
Yes, the ANKOM RF Gas Production System can monitor negative pressures. When performing oxygen consumption studies, a NaOH or strong base is used to scavenge the CO2 produced by the aerobic metabolism. This produces a negative pressure as the O2 is...
Cause: This fault occurs when the temperature sensor in the in-line heater reports that the in-line heater is not reaching the required 110˚C within the 90 seconds allotted during an IDF water rinse. The fault message on the touchscreen display will...
An E2 Fault is declared when the thermistor to the in-line heater is reporting an erroneously low reading of < 10˚C. IMPORTANT: An E2 fault can be caused by cold buffer running through the instrument. If you store your buffer solutions in the...
Possible Causes: A leak has occurred at the agitator shaft. The packing nut requires attention. Refer to Service Procedure Agitator Packing Maintenance and Nut Adjustment (AS001). If tightening the packing nut does not stop the leak, you will need to...
Test the rinse water with litmus paper during the last minute of the fourth hot water rinse. If the test indicates the presence of acid, repeat with fresh, hot water until a neutral pH is achieved.
You can see unexpectedly high values when hydrolyzing fat samples if the samples are not adequately dried after the hydrolysis step. Possible reasons for insufficient drying include: (1) Dryer is not working properly - Filter needs to be replaced -...
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...
Neutral detergent consists of varying amounts of 4 dry chemicals and triethylene glycol. If you remove only a portion of the dry chemicals to make less than 20L of solution, it is impossible to know if the solution has the correct ratio of chemicals...
Amylase is utilized to help digest the starch in the sample. Even using expired Alpha Amylase, it is highly likely the non-starch components, as well as most of the starch, are gone. Put the Filter Bags in a 1 L beaker with 80 °C water and 8 ml of...
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...
With the lignin procedure, two common errors will create false high values. (1) The first error is placing the F57 Filter Bags into the 72% sulfuric acid when there is moisture in the bags and samples. To avoid this situation, after the ADF procedure...
All food and feed samples can be run on the ANKOM FLEX.
This fault indicates a System Integrity Failure. One or more columns or round bottom flasks did not reach or hold pressure properly. To resolve an MF24 fault: 1. Confirm the Low N2 setting is: 2.6 - 3.0 PSI. See Section 6.7.2 of the FLEX Operator's...
The ANKOM FLEX runs one method at a time. All four positions on the instrument run the same selected method and are controlled in unison; the positions are not independently controllable.
The current method uses 250L nitrogen per run of four assays.
Tips to avoid vessel leaks: (1) Do not spray water directly on the filter. Spray on the side of the vessel, so that it will flow onto the filter without force. You could also spray onto the mixer. (2) Always add the stir bar to the vessel before...
Sorbent Disposal Bags ( Part #: FLEX-SDB ) hold spent sorbent from four SPE columns while allowing solvents to evaporate overnight in a hood. Dispose of the empty SPE columns and Sorbent Disposal Bags using your internal hazardous waste SOPs and SDS...
ANKOM recommends replacing the delivery tubing every one to two years depending on the use of the instrument. Order the Delivery Tube Replacement Set ( Part #: TDF126 ) by contacting ANKOM Technology at (315) 986-8090 or by ordering from the website...
The drain valve has been told to open but after 30 seconds the drain-open switch has failed to open the drain. Possible Causes: (1) The wires on the drain valve have become disconnected. Unplug the instrument, check the drain valve and reattach any...
