8. Press ENTER on the Keypad and follow the prompts on the Display to set up the instrument for ADF
analysis.
9. Close the Vessel Lid and tighten it by turning the Vessel Clamp
Handle.
If you do not want to use the Cubitainers to automatically add your solutions,
you can manually fill the vessel for each procedure. First make sure that the
hoses to the Cubitainers are disconnected. Immediately after executing step
10 below, pour 2L of solution directly into the vessel. Please note that the
solution must cover the level sensor in order for the instrument to start its
operation. Once agitation begins, close the Vessel Lid and continue the
procedure with step 11.
10. Press START on the Keypad. Solution from the Cubitainer will flow into the vessel through Port B.
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.
11.
When the “Extraction Done” message appears on the Display, the analyzer operation is complete. Open
the Vessel Lid, remove the bags and place them in an appropriately sized beaker.
12. With your hands, gently press out excess water from the bags into the
beaker and pour off the water from the beaker.
13. With the bags in the beaker, add enough acetone to cover them. Let the
bags soak in acetone for 3 – 5 minutes. Then pour off the acetone.
14. With your hands, gently press out excess acetone from the bags into the
beaker and pour off the acetone from the beaker.
15. Remove the bags from the beaker and place them on a wire screen to air-dry.
Hazardous Materials
–
Do NOT place bags in an oven until all acetone has
evaporated.
16. Place air-dried bags in the oven and heat at 102°C ± 2° for 2 – 4 hours (depending on the oven).
When running a lignin procedure or a sequential (NDF/ADF or
NDF/ADF/Lignin) with F57 Filter Bags it is important not to dry the bags
overnight after the NDF or ADF procedure. A drying timeframe of 2-4 hours
at 100°C to 105°C is sufficient to thoroughly dry the bags after each
procedure. Extended drying times or too high a temperature can compromise
the bag’s filtration media.
In addition, after the fourth rinse during the ADF
procedure if you would
like to confirm the acid has been completely rinsed
from the bags, capture some water from the waste tube and check the water
with litmus paper.
