Application Analysis

For most data analysis applications the first three to five principal components give the predominant part of the variance. 

Besides these main categories, a large number of hybrid visualization techniques also exist, which arc combinations of the methods described. Well-known hybrid approaches arc the 2D or 3D glyph displays. These techniques combine the multidimensional representation capabilities of icon-based methods with the easy and intuitive representations of scatter-plot displays, Therefore these techniques can also be frequently found within chemical data analysis applications. 

The determination of such compounds was measured by their effect on the oxidation signal of tire guairine peak of calf tlrymus DNA immobilised on tire electrode surface and investigated by chronopotentiometric or voltammetric analysis. Applicability to river and wastewater samples is demonstrated. 

Phenols hold an important place among organic pollutants, which need to be constantly monitored in waters and in places of militai y activities. Sampling of phenol matrix is conducted with solid face extragents (SPE) with further HPLC or GC analysis. Application of the known SPE usually is ineffective as it doesn t give the possibility to provide full extraction of the analyt (microcontents) in the matrix media. Therefore SPE application needs further progress in their selectivity. 

Over the last seventeen year s the Analytical center at our Institute amassed the actual material on the application of XRF method to the quantitative determination of some major (Mg, Al, P, S, Cl, K, Ti, Mn, Fe) and trace (V, Cr, Co, Ni, Zn, Rb, Sr, Y, Zr, Nb, Mo, Ba, La, Ce, Pb, Th, U) element contents [1, 2]. This paper presents the specific features of developed techniques for the determination of 25 element contents in different types of rocks using new Biaiker Pioneer automated spectrometer connected to Intel Pentium IV. The special features of X-ray fluorescence analysis application to the determination of analyzed elements in various types of rocks are presented. The softwai e of this new X-ray spectrometer allows to choose optimal calibration equations and the coefficients for accounting for line overlaps by Equant program and to make a mathematic processing of the calibration ai ray of CRMs measured by the Loader program.
