The ANKOM fiber instruments can analyze for either Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF), or Crude fiber. NDF consists of Hemicellulose, Cellulose, & Lignin. ADF consists of Cellulose and Lignin. Acid Detergent Lignin (ADL) consists of lignin only. ADL analysis can be done after ADF analysis, in beakers or in the ANKOM Daisy instrument. Therefore, Hemicellulose content can be determined by subtracting ADF from NDF. Cellulose content can be determined by subtracting ADL from ADF.
