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 .

Oximes, hydroxamic acids and related species are often used as reagents in inorganic analytical chemistry for precipitation, gravimetric and volumetric determinations as well as for preconcentration, extraction, derivatizations and subsequent determination of analyte using instrumental techniques. A brief review of analytical chemistry in general and of these species in particular follows. 

Our review on the use of oximes and hydroxamic acids in inorganic analytical chemistry showed that these reagents are/were most frequently used for gravimetric determinations, determinations based on complexation, spectrophotometric determinations and separations, while their use for column separations, as electrode sensors, as supporting electrolytes or compounds that enhance sensitivity of determination is less common. Additionally, it was noticed that the analytical chemistry of anions is less advanced than that of cations and for this reason this chapter was limited to analytical chemistry of metallic cations.

In transactinide chemistry research, gas phase separation procedures play an important role. Already, the very first investigation of rutherfordium has been conducted in form of frontal isothermal gas chromatography in a chlorinating atmosphere [1]. The success of gas chemical separations in transactinide research is quite remarkable since gas chromatography is, in general, of minor importance in inorganic analytical chemistry. 

Determination of the sulfate content requires the preliminary hydrolysis of galac-tans by the action of 1 M HC1 at 100 °C for 6 h (hydrolysis in 2 M trifluoroacetic acid can also be used for simultaneous determination of monosaccharides and sulfate). Quantitative estimation of sulfate in hydrolyzates can be performed by many methods known from inorganic analytical chemistry,218,219 but the most popular procedure in the case of galactans is turbidimetry of stabilized suspensions of BaSO.4. It was suggested in the early 1960s220 and is widely used at present in the slightly modified form.221...
