The fiber analyzer is an instrument
that cooks the sample according to the commonly used acid-base decomposition method and performs gravimetric determination to obtain the fiber content of the sample.
Note 1.
The weighing process should be accurate (close the balance to block the door), do not hold the crucible by hand, take it with a clip; 2.
When adding liquid to the inside of the instrument in the second and subsequent steps, it is necessary to ensure that the liquid is hot to avoid the explosion of the instrument end tube due to the difference in temperature; 3.
Instrument cleaning do not use washing powder, washing clean and other solvents, choose hot water for cleaning, if it is indeed cleaned, you can use a small amount of solvent for cleaning; 4.
After the completion of acidosis (or alkalinelysis), the liquid should be carried out slowly to prevent the floating sample from adhering to the wall of the digestion tube, if the sample adhesion is relatively firm, can not be cleaned with water, can be gently brushed off from the bottom with a soft brush; 5.
Quartz crucible gently hold and put lightly, avoid crushing, collapsing, shattering, etc.
; 6.
If the crucible is obviously blocked when used for a long time, it can be dried and put into the horse furnace for about 500 degrees for 1-2 hours, and then cleaned after cooling;
