A Neotec infrared instrument was evaluated for determination of protein contents of wheat and barley. Correlation coefficients between protein content determined on the instrument and by the Kjeldahl method were highly significant (0.97 to 0.98). Accuracy of analyses, measured by the standard error of a single test was 0.07 to 0.16, giving a coefficient of variability of 0.6 to 1. 1%. Method of grinding samples affected particle size and type. Particle size did not directly influence protein values; however, greater accuracy and reproducibility were achieved with smaller particle sizes. Packing density inside the loading tell also influenced the analytical results.
