Crude Fiber Analysis Procedure using the ANKOM
2000
Fiber Analyzer
To perform Crude Fiber analysis on prepared samples, follow the procedure detailed below.
If you are changing from one analysis type to another, flush the system before
running. See the “Flush Procedure” section of this manual for more
information.
1. Verify that the hot water supply is on and the drain hose is securely positioned in the drain.
2. Attach each Cubitainer hose first to the Cubitainer and then to
its specific chemical port. Port A is used for Crude Fiber Acid
solution. Port B is used for Crude Fiber Base solution.
The solutions are gravity fed into the instrument ports. The bottom of the
solution level must be at least 5” (13cm) above the port. The top of the
solution level can be no more than 20” (50cm) above either port or the
solution will overflow into the drain.
3. Open the Vessel Lid.
4. Place the Bag Suspender with the samples into the Vessel.
5. Place the Bag Suspender Weight onto the Bag Suspender rod to hold the trays in place.
6. Turn the instrument’s Power Switch to the ON position. The Display will light and allow you to select an
analysis procedure.
7. Press the arrow keys on the Keypad until you see “Select Crude
Fib” on the Display.
The Crude Fiber analysis will use the following default settings:
•
40 minute Acid digestion
•
40 minute Base digestion
•
two 5 minute Acid rinses
•
three 5 minute Base rinses
If you want to run a custom Crude Fiber analysis that allows you to set the
digestion times and the number of rinse cycles, press the arrow keys until you
see “Select Custom” on the Display.
8. Press ENTER on the Keypad and follow the prompts on the Display to set up the instrument for Crude
Fiber analysis.
