Abstract
Digital computing methods for4components mass spectra reported in the previous work were extended up to7, 10and17components mass analyses. Pattern coefficients of each unicomponent and the spectra of the blending samples were measured and analyzed. It is shown that these methods are applicable for the routine analytical work also. The methods were also applied to the weighted least squares methods. Barnard and Fox's method was applied to4components mass spectra reported in the previous work. The average of the standard deviations of the results was0.156mol%which was twice as worse as that without weight. In the new method, the weights for the mass peaks were adjusted so that they give nearly equal residuals. The results thus obtained were considerably improved and had the standard deviations of about0.037mol%.
