Conf. on Spectral Analysis, Szombathely, 1984, p. 1, Spectrographs analysis was carried out with different additives: Li 2 B 2 0 7 , LiF and Li 2 C0 3 in the case of mediaeval glasses. Their effect on the standard deviation, sensitivity and limit of detection was evaluated. Karmacsi Á. — Zimmer K. — Abo Bakr M. El-Nady: investigation of concentration distribution in glasses by electron probe microanalysis = Spectrochim. Acta 39B, p. 1487, (1984) On the surface and in the bulk of mediaeval glasses, the distribution of components has changed owing to the long contact with soil. After preliminary investigations by emission spectrochemical analysis, the concentration distribution of elements was determined in the glass samples by electron probe microanalysis. Moreover, inhomogeneity was studied in combination with the investigation of surface roughness. Danzer, K — Singer,R. — Maurer,F. — Flórián K — Zimmer K: Mehrdimensionale Varianz- und Di skriminanzanalyse spektrographischer Daten von Glasperlenfunden = FreseniusZ. Anal. Chem. 318, p. 517.(1984) Pattern recognition methods as applied to multivariate investigations of multidimensional data sets permit the detection of complex connections between properties and the measured data including the interaction of the variables. In this case, statistical methods like multidimensional variance and discriminant analysis are advantageous because of the possibility to weight the variables according to their influence on the classification. Application of multidimensional variance and discriminant analysis to a set of spectrographically determined concentrations of colouring elements in historical glass bead findings yields good classification results after eliminating univariate detectable outliers. Abo Bakr M. El-Nady — Zimmer K. — Záray Gy .: Spectrochemical analysis of mediaeval glasses by means of inductively coupled plasma and glow dischange sources = Spectrochim. Acta 40B, p. 999.(1985) For the analysis of mediaeval glass fragments, the inductively coupled plasma (ICP) and the Grimm type glow discharge source (GDS) were used. For ICP measurement, the glass samples were digested with a mixture of sulphuric, nitric and hydrofluoric acids. For GDS investigations the glass powder, mixed with Cu or Zn powder, was pressed to pellets. The sputtering rate was investigated in the case of standard and glass samples. Analytical curves were found to be linear over a wide concentration range for the investigated elements Fe, Mn, AI , Zn, Cr, Ni, Cu, Sn, Ti, V, Pb and Ag. The limits of detection and relative standard deviations met the requirements for archaeological glass analysis.
