Ana Teruel Doñate,Ana Allueva Pinilla problem. Now tables are adequate, this is reduced to the choice of lines to measure, and the method of measurement chosen is an important decision. The s.p.d. method calls for the selection of lines of moderate or low intensity, and avoids the lines of high ‘sensitivity’ which are used for trace an

Optimal Design in Longitudinal Data Modelseir manipulations, and the supervision of the arc during burning. Exposures of up to 8 minutes need care to maintain the arc length and position uniform throughout the exposure period. The difference between the .-method and the .-method is fully explained here, as is sample preparation and the choi

Introduction,Spectrochemical analysis methods by means of an electric arc are not non-destructive. A certain quantity of the material to be analysed is necessary. A certain quantity (5 or 10 mg) is evaporated in the arc and is therefore lost as a vapour into the surrounding air.

Arcs and Atomization,hese reactions are briefly discussed in Section 1.3 and in greater depth for certain of the elements separately. The rate of evaporation of the element being analysed depends on (i) whether it evaporates as an element or a compound, (ii) on the temperature difference between its boiling point and th
