Abstract/OtherAbstract:
|
Four international ring trials for NIRS amino acid analysis of feed raw materials have demonstrated for the first time that the calibrations developed by Degussa allow reliable and precise predictions of essential amino acids in up to 44 NIR spectrometers. Different standardization techniques were compared, and the effectiveness of using spectra of the host instruments as repeatability files was studied. The ultimately achieved reproducibility of 2-3% CV for almost all analyses in the network is considerably better than ring trial results for wet chemical amino acid analysis. |
