Analytical total

If all constituents are separately measured, or are calculated by stoichiometry, as in the case of oxygen, then the analytical total, which is the sum of all elements plus any calculated by stoichiometry, conveys useful information. If the analytical total is above 102%, a possible mistake in the measurement of the electron dose or an unexpected change in spectrometer parameters is likely. If the analytical total is significandy below 98%, an additional consdtuent is likely to have been missed.

At the beginning of the voltammetric experiment the chemical reaction (2.29) is in equihbrium, characterized by the equilibrium constant K. The latter is the most important thermodynamic parameter of the system, related to the rate constants by K= Before the voltammetric experiment, the bulk concentrations of Y (cy) and R (c ) are dictated by the equilibrinm constant K and the analytical (total) concentration of the Y (c ) as follows Cy + Cr = c and K=. Hence, the experimental conditions prior to the voltammetric experiment are represented by the following initial conditions ... 

AR = alumina ratio (alumina modulus). ASR = alkali silica reaction. LSF = lime saturation factor. SR = silica ratio (silica modulus). C, = analytical (total) concentration of x, irrespective of species, [x] = concentration of species x. x = activity of species x. RH = relative humidity. =... 

BuLi) n BuLi When practically all organometal is aggregated, the concentration of (BuLi) is n times less than the analytical total BuLi concentration. It then holds that > ini, = ki(K7n) /"[BuLi] /"[M]. 

The majority of wet-chemical analysis is for the silica-aluminosilicate-alumina range, and this is used to illustrate the methods used. The oxides determined are the normal eight (those of silicon, titanium, aluminum, iron, calcium, magnesium, potassium, and sodium). In ceramics, it is traditional to refer to the elements as their oxides. Eor the analyst, this has the advantage of providing an analytical total to cross-check the accuracy of the analysis.
