Applications analytical chemistry

The scientific interests of Anatoly K. Babko ranged widely, especially in regard to fundamental aspects of analytical chemistry, applications of organic reagents in inorganic analysis, chemistry of complex compounds (including heteropolyacids), analytical applications of complex compounds in photometry, luminescence and chemiluminescence, ion chromatography, and liquid-liquid extraction. 

It should be recognized that, in some cases, it is not difficult to set up a traceable measurement system. The best examples of this are in physical metrology where traceability is often based on direct measurements of the SI units. There is also general agreement that a similar SI fink is highly desirable in the case of chemical measurements, but, for a variety of reasons, direct chemical traceability is difficult to achieve in most of the analytical chemistry applications. Only a very few analytical chemistry procedures exhibit a direct measurement capability that allows the set-up of a traceable measurement pathway such as in physical metrology measurements most of these procedures have been accepted as primary methods if carried out under certain constraints (CCQM 1998). 

In discussing these pathways and considering the broad spectrum of analytical chemistry applications in contrast to the limited supply of CRMs, one has to keep in mind that the unbroken chain of comparisons may be hterally demonstrated in only a few instances and that for a long time to come data are accepted by inferred quality, including traceability.

Although Euclidean and Mahalanobis distances are the ones most commonly used in analytical chemistry applications, there are other distance measures that might be more appropriate for specific applications. These are discussed in reference [75]. 

We start with butane-2,3-dione dioxime, more commonly known as dimethylglyoxime (dmg). It is a classic reagent for the analysis of NP, the green aqueous solution of metal ions transforming into a vibrantly red precipitate of Ni(dmg)2 complex it is one of the stars of the show in Ponikvar and Liebman s analytical chemistry chapter in the current volume. Here the stereochemistry is well-established and well-known—both OH groups are found on the same side as their adjacent CH3 group on the butanedione backbone. There have been several measurements of the enthalpy of formation of this species for which we take the one associated with this inorganic analytical chemistry application, i.e. with diverse metal complexes and chelates .

SFE has also replaced many regulated solvents in analytical chemistry applications in recent years, primarily because it provides a more reliable measure of the concentrations of environmental contaminants and can play an important role in pollution assessment, abatement, and control. Advantages have been shown for using SFE compared to the conventional Soxhlet extraction with toluene for determining the presence of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in ashes from a municipal incinerator (Dolezal et al., 1995). SFE allows the complete extraction of the analytes from the sample, whereas conventional extraction results in an incomplete, and hence, inferior extraction.

Another assumption, which becomes apparent when one carefully examines the model (Equation 8.7), is that all of the model error (f) is in the dependent variable (y). There is no provision in the model for errors in the independent variable (x). In PAC, this is equivalent to saying that there is error only in the reference method, and no error in the on-line analyzer responses. Although this is obviously not true, practical experience over the years has shown that linear regression can be very effective in analytical chemistry applications. 

Although Euclidean and Mahalanobis distances are the ones most commonly used in analytical chemistry applications, there are other distance measures that might be more appropriate for specific applications. For example, there are standardized Euclidean distances, where each of the dimensions is inversely weighted by the standard deviation of that dimension in the calibration data (standard deviation-standardized), or the range of that dimension in the calibration data (range-standardized). 

Green analytical chemistry—application of the concept of sustainability in analytical laboratories... 

To illustrate the use of experimental designs in an analytical chemistry application, we will examine a problem taken from the agrochemical industry. The problem under investigation was to develop a robust calibration model for several commercial products based on UV spectral measurements. By the term robust model, we assume that the model will be able to give acceptable predictions even if there is some moderate variation in the controlled and uncontrolled variables. 

This book continues in the practical tradition of chemometrics. Multivariate methods and procedures that have been found to be extraordinarily useful in analytical chemistry applications are introduced with a minimum of theoretical background. The aim of the book is to illustrate these methods through practical examples in a style that makes the material accessible to a broad audience of nonexperts.
