Crude Fiber Analysis Procedure using the ANKOM
DELTA
Automated Fiber Analyzer
To perform Crude Fiber analysis on prepared samples, follow the procedure detailed below.
NOTE:
The instrument automatically flushes the chemical lines and valves after each run.
1. Verify that the hot water supply is on and the drain hose is securely positioned in the drain.
2. Attach the crude fiber acid and crude fiber base tubes to their appropriate chemical containers
(Cubitainer, chemical tank, etc.)
NOTE:
The chemicals are pumped into the instrument via the pump and valves.
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.
IMPORTANT:
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.
9. Close the Vessel Lid tightening it by turning the Vessel Clamp Handle.
10. Press START on the Keypad. Solution will flow first into the vessel through the crude fiber acid valve.
NOTE:
Once the analysis begins, digestions and rinses occur automatically, with the
analyzer Display providing information about the process time remaining, the
temperature, and the pressure. Pressing STOP on the Keypad at any time during the
analysis ends the operation and opens the drain to exhaust the solution.
