[Spectrophotometric analysis of the multicomponent system: dihydralazine sulfate, hydrochlorothiazide and reserpine]. / Untersuchungen zur spektrometrischen Analyse des Mehrkomponentensystems Dihydralazinsulfat, Hydrochlorothiazid und Reserpin.

With respect to their performance a computer aided spectrometric analysis of multicomponent system dihydralazine sulfate hydrochlorothiazide and reserpine was made under various conditions. To find out the advantageous measuring points the difference spectra were determined. The influence of the number of measuring points, the single and mixture calibration and the dimensiation of calibration matrix to accuracy and precision was investigated and the limits of the determination for the three component system are discussed.
