title: Variations in mechanical sampling: their causes and effects.
abstract: Three characteristics of a sample of AutoAnalyzer Sampler II modules have been measured: eccentricity of the cam, eccentricity of the spindle driving the cam, and the lengths of the chords of the cam lobes. Imprecision in timing may make a significant contribution to analytical error.
