FIWE is a fiber analyzer suitable for raw fiber extraction, conventionally known as an indigestible residue. The Weende method is the oldest analytical procedure still in use today, in which fiber concentration is measured as crude fiber (CF). Weende method has been now largely replaced by the Neutral Detergent Fiber (NDF), a method developed by Van Soest, being now the most common measure of fiber used for animal feed analysis. It measures most of the structural components in plant cells (including lignin, hemicellulose and cellulose), but not pectin. Another application is Acid Detergent Fiber (ADF), that is a portion of the plant fiber and includes cellulose, lignin and variable amounts of xylans. ● Total raw fiber extraction using Weende technique ● Neutral & acid detergent fiber with NDF, ADF, Van Soest extractions ● Acid detergent lignin extraction with ADL & Van Soest methods ● Fiber fraction analysis (cellulose, hemicellulose & pectin) ● Links boiling, rinsing and filtration ● Single or multiple samples can be processed ● Rapid analysis – 2 hours vs. 6 hours with manual systems ● Reliable results ● High reproducibility ● Back-pressure pump prevents clogging of crucibles
