ADF Analysis Procedure using the ANKOM
200
Fiber Analyzer
NOTE:
If you are following the acid detergent procedure with an acid detergent lignin, you
can find the lignin procedure on our website at www.ankom.com.
To perform the ADF analysis on prepared samples, follow the procedure detailed below.
IMPORTANT:
The Vessel must be at room temperature before beginning an ADF analysis.
1. Verify that the Exhaust Hose is connected to the instrument and securely positioned in the drain.
2. Turn the instrument Power Switch to the ON position.
3. Lift the Lid Handle to open the Vessel Lid.
4. If the temperature on the Temperature Controller display is higher than room temperature, fill the Vessel with cold tap
water. The temperature on the Controller will decrease. When the value on the Controller reaches its lowest number
and starts to increase, open the Exhaust Valve and exhaust the water. Repeat this process until the number on the
Temperature Controller equilibrates to room temperature.
5.
Place the Bag Suspender with the samples and the Bag
Suspender Weight into the Vessel.
6.
Pour a maximum of 2 L of Acid Detergent solution into
the Vessel.
7.
Press the
HEAT
and
AGITATE
buttons on the front of the
instrument so they are lit. Look in the Vessel to confirm
agitation.
8.
Close the Vessel Lid.
9.
On the Timer/Clock, set the Timer to 60 minutes and
press the Start/Stop button.
10.
When the Timer sounds, the digestion process is
complete. Press the
HEAT
and
AGITATE
buttons to turn
them off (the buttons will not be lit when they are off).
Open the Exhaust Valve (slowly at first) and exhaust the
hot solution BEFORE opening the Vessel Lid.
IMPORTANT:
Because the Vessel is under pressure, the Exhaust Valve must be opened to release
the pressure and the solution BEFORE opening the Vessel Lid.
11. After the solution has been exhausted, open the Vessel Lid slowly to allow air to push any remaining liquid out the
Exhaust Hose.
12. Close the Exhaust Valve.
13. Add 1900 ml - 2000 ml of 70°C - 90°C rinse water.
IMPORTANT:
During the rinse process, if the
HEAT
button is OFF, the Vessel Lid can be open. If
the
HEAT
button is ON, the Vessel Lid must be closed.
14.
Press the
AGITATE
button.
15. On the Timer/Clock, set the Timer to 5 minutes and press the Start/Stop button.
