Reproducibility of pyrolysis-gas chromatographic analyses of the mould Penicillium brevi-compactum.
The reproducibility of multivariate measurements is discussed. Reproducibility of a second kind is defined, in which part of the variability between samples is described by a principal components model. The use of this generalized reproducibility is shown to give an improved precision in the pyrolysis-gas chromatography of a Penicillium species.
