[Bartlett's test in the statistical determination of amino acids using an automatic analyzer].

Bartlett's test was applied to estimate the precision of the determination method of amino acids using the automatic analyser "Unichrom". The calculations were done on the basis of the results obtained from determinations of the amino acids in 8 different materials of plant and animal origin. No significant differences among standard deviation of 11 amino acids were found; this allowed the authors to express the precision of the method for these amino acids by mean standard deviation.
