The crude fiber analyzer can measure the crude fiber content in various grains, feeds, grains, foods and other agricultural and sideline products. It can simultaneously measure 6 samples and automatically control the temperature.
The CXC-06 crude fiber analyzer is also called feed crude fiber analyzer. It is an instrument that digests samples according to the commonly used acid-base digestion method and performs weight measurement to obtain the crude fiber content of the sample.
The crude fiber analyzer is not an exact chemical entity, but a rough composition measured under generally recognized mandatory conditions, which is determined by the content of crude fiber, lignin, cellulose and hemicellulose.
Principle of Crude Fiber Tester
Using acid and alkali of accurate concentration, digest the sample under specific conditions, and then use ethanol to remove the soluble matter. After high temperature burning, the amount of minerals is deducted, and the content is called crude fiber. It is not an exact chemical entity, but a rough composition measured under generally recognized mandatory conditions. Among them, cellulose is the main component, with a small amount of hemicellulose and lignin.
|Measurement object||the content of crude fiber in various grains, feeds, grains, foods and other agricultural and sideline products Number of test samples: 6/time|
|Repeatability error||the crude fiber content is below 10%, the absolute value error is ≤0.4%
The crude fiber content is above 10%, and the absolute value error is ≤4%
|Measurement time||about 100 minutes on the instrument (including 40 minutes for acid, 40 minutes for alkali, 20 minutes for suction and washing)|
