title: Equivalency of protein determination in feed on Bran & Luebbe Traacs 800 autoanalyzer with AOAC semiautomated method: minicollaborative study.
abstract: A new generation of autoanalyzers was collaboratively studied for equivalency with instrumentation described in the AOAC method for crude protein in animal feeds. Twenty predigested samples were analyzed by 4 collaborators using standards that were provided. Means were comparable; the overall average difference was 0.07% protein. Analysis of variance indicated no evidence for an instrument difference. The method describing use of the Traacs 800 autoanalyzer as an alternative system has been adopted official first action.
