Since your GPM software runs on a PC, power sources, the operating system (e.g., Windows) settings, as well as other programs and network connections on the PC can affect the GPM software. Power If your PC is being powered by a battery or an...
If you do the de-fat procedure using ANKOM XT4 filter bags, after you complete the Kjeldahl digestion, there will be a white substance on top of the resulting liquid. This substance is the PTFE coating on the XT4 filter bags. This substance will NOT...
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...
The FLEX Vitamin and Cholesterol analysis run time is a little over two hours. Technician time is only five to ten minutes of set-up prior to running the instrument. This includes weighing samples into each digestion vessel and loading the digestion...
Yes. A check sample, Infant Formula, ( Part #: FLEX65 ) can be purchased on the ANKOM website.
The SPE columns and vessel filters can only be purchased through ANKOM.
In the event of a Drain Time-Out Fault (MF7) or an Abort during a Drain Module, users must flush the lines beneath the vessels to clear the residue prior to starting a new run. For more information, refer to Section 17 of the FLEX Operator’s Manual...
The preprogrammed vitamin methods are based on a combination of the following official methods: Vitamin & Cholesterol methods based on: AOAC 2011.07, EN-12823-1, EN-12822 Total Fat method: The test portion is treated under heated hydrochloric acid...
Check to ensure the procedures sent with your instrument were followed. Some possible variables that may affect your results are: General Problems: Neutral Detergent chemicals can come out of solution. Heat and stir to bring back into solution. The...
Carry-over is extremely low (~0.08%) and therefore undetectable for most food and feed samples. When running concentrates, such as vitamin supplements, use a wash bottle to rinse the round bottom flask adapters with hexane prior to the next run to...
Possible Causes: The rinse water supply temperature did not meet method standards. This may affect results with certain samples. Make sure the water supply has a temperature no less than 50°C for Crude Fiber, or no less than 70°C for ADF and NDF...
When the instrument is turned on, the drain valve opens to vent the vessel. If the drain open/close switch is not sensed by the computer, this fault occurs. Possible Causes: (1) Wires on the drain valve have become dislodged. Connections may have...
Possible Causes: (1) The level sensor has failed to detect the liquid that is in the vessel. If the vessel is full and this fault screen appears, press <STOP> to drain the fluid. You may want to capture the solution and re-use it. Refer to DELTA...
The vessel temperature has exceeded the maximum limit. Possible Causes: (1) The solution level is low in the vessel, but the level sensor is indicating full. The level sensor has two main components that work together. These components are a Level...
Possible Causes: Possible Causes: Leakage has occurred at the agitator shaft; therefore, the packing nut requires attention. See DELTA Service Procedure Agitator Packing Maintenance and Nut Adjustment (DES001). If tightening the packing nut does not...
To properly set up your instrument for the various fiber analyses, refer to the DELTA Operator's Manual sections on NDF, ADF, and Crude Fat analyses.
Possible Causes: The packing nut may be too tight. For proper tightening instructions, refer to DELTA Service Procedure Agitator Packing Maintenance and Nut Adjustment (DES001). The packing assembly may have corrosive buildup. If periodic maintenance...
For instruments with version 3.78 or newer software perform the following diagnostics routine: (1) Run a Line Charge two times with “All” selected with the flush tube assembly installed using deionized water. This will prime the lines in the...
A nitrogen generator can be used as long as it meets the following requirements for the proper operation of the FLEX instrument: N2 purity, Industrial Grade (Grade 4.8) which is 99.998% or purer N2 Flowrate of 10LPM at 6.9 bar minimum Supply N2...
Rinse water can come directly from the tap. It does not have to be distilled.
"ANKOM Technology has been great to work with as we developed unique methods to advance our inoculate technology. We like the speed and ease of operation ANKOM products provide." -Lesa Nuzback, Dupont Pioneer Livestock Nutrition Center The DuPont...
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 most likely a problem with the circuit board. Static discharge, high humidity/moisture contact with the circuit board, or physical damage from dropping, etc. may have caused the problem. Contact ANKOM Technology for further assistance.
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.
Yes. If you are looking to get some hands-on experience with the system before putting it to full use in a study, or if you observe results that you don't understand and want to verify that the ANKOM RF Gas Production System is functioning properly...
First, be sure Synthetic Grease w/PTFE ( Part #: RF41 ) was used on the lip of the bottle and the lip of the septa port on bottles so equipped. This aids in making a tight seal. Second, inspect the gasket which seals the module top to the bottle. It...
You should replace the gasket whenever it appears damaged. If you open and close the bottles once a week (on average), you should replace the gasket once every six months.
Refer to RF Service Procedure Vent Valve Cleaning (RFS006).
Battery life can be extended by unplugging the battery (Part #: RF16 or RF46 ) when a module is not being used. In addition, utilizing a longer live interval, such as 60 seconds, will extend battery life. Minimizing the use of the "Open Valves"...
Using the 10-Station Battery Charger (Part #: RF25 ) it should take only three hours to fully charge your rechargeable batteries (Part #: RF16 or RF46 ). The green indicator lights on the charger should begin to turn green within two to three hours...
The sensors are accurate to within +/-2°C over a range of 5°C - 60°C. To account for any Module-to-Module differences in temperature sensing capability, the GPM software provides a calibration screen that can be used before data recording begins...
This is most likely because the default AutoSave location is in a location that your computer may not have "write" access to. In addition, behind the scenes, the program is also attempting to save a log file of every communication between the...
Fifteen RF modules with 100-500ml size bottles attached will fit in the 20-liter Water Bath (Part #: WB20SH or WB20ISH ). Eight RF modules with 1-liter bottles attached will fit in the 20-liter Water Bath (Part #: WB20SH or WB20ISH ).
Typically, a fully charged rechargeable battery (Part #: RF16 or RF46 ) should be able to power a module for approximately ten days under normal conditions (20°- 40°C GPM settings of 60-second Live Interval and one valve opening sequence per hour.)...
The volume of "dead space" between the vent valve and the septum on an RF module is .003 cubic inches for the RED capped modules, and .043 cubic for the BLACK capped modules.
Possible Causes: The solution temperature has exceeded the maximum limit. Perform the boil test detailed in Service Procedure Boil Test (AS013).
The instrument is experiencing a pressure fault. There are three possible reasons for this fault. (1) More than 2 L of solution was in the vessel during the digestion process. A pressure fault will most commonly occur if there is more than 2 L of...
