The lUPAC Commission for Analytical Nomenclature defines the calibration curve [138] as the dependence of the electromotive force of the given ISE -reference electrode cell on the logarithm of the activity or concentration of the given substance. It is recommended that the potential be plotted on the ordinate (the vertical axis) and the logarithmic function of the activity or concentration on the abscissa (the horizontal axis), with the concentration increasing from the left to the right. 

The selectivity coefficient was defined in chapter 3 and several theoretical relationships were given for this quantity for various ISE systems. Several methods have been proposed [38, 120,123, 135] for the determination of selectivity coefficients two basic methods were recommended by the lUPAC Commission for Analytical Nomenclature [138],... 

The Commission on Analytical Nomenclature of the Analytical Chemistry Division of the International Union of Pure and Applied Chemistry has pointed out that confusion and ambiguity can arise around the use of the term sample and recommends that its use is confined to its statistical concept. When being used to describe the material under analysis, the term should be qualified by the use of laboratory sample or test sample , for example. 

At the beginning of this passage some definitions concerning the term sample are necessary. According to the IUPAC Commission on Analytical Nomenclature [HORWITZ, 1990] the general definition is The sample is the actual material investigated, whether di-...

For recommendations ot thd lUPAC Commission on Analytical Nomenclature for chromatography, see L. S. Ettre. Pure Appl. Ctum.. IW3.65, S19. The committee recommends the use of ihc term distribution constant Kc rather than the older term "partition c cflicient," or "partition ratio." K. Be aware that Iwth ternts are found in the chromatographic literature. 

In the older literaiure. this constant was called the capacii> factor and symbolized by k. In 199.V however, the lUPAC Commission on Analytical Nomenclature recommended that this constant be termed the retention factor and symbolized by k. 

A book chapter covered all aspects of modem TLC (Chapter 7, Ref. 44), and general review articles were written by Nyiredy (45), Poole and Poole (29,46), Szepesi and Nyiredy (47), Nyiredy and Szepesi (48), Jork (49,50), Touchstone (51), and Sherma (52). The lUPAC Commission on Analytical Nomenclature published approved terms and definitions for planar chromatography (53).

The Electroanalytical Chemistry Commission, which is a subdivision of the Analytical Chemistry Division of the International Union of Pure and Applied Chemistry (lUPAC), provides authoritative guidance on nomenclature, terminologies, symbols, units, and procedures used in electroanalytical chemistry. Use your Web browser to connect to http //cliemistry.brookscoIe.coin/skoogfac/. From the Chapter Resources menu, choose Web Works. Locate the Chapter 19 section, and click on the link to the Commission for Electroanalytical Chemistry Web site. Then click on the link to projects, choose one of the published reports, and view the Adobe Acrobat PDF file containing the report. Write a short summary of the report and describe its purpose. 

The nomenclature used in Analytical Chemistry, and therefore in this encyclopedia, is that agreed and published by the International Union of Pure and Applied Chemistry (lUPAC) after deliberations by numerous specialist Commissions and Working Parties. The more fundamental definitions and values are to be found in Quantities, Units and Symbols in Physical Chemistry (1993), 2nd edn., Oxford Blackwell Scientific Publications, prepared for publication by Mills I, Cvitas T, Homann K, et al. (the so-called Green Book). Some of the information from this publication is included in these appendices, as are the currently accepted values of atomic weights, isotopic, composition, etc., which are the responsibility of the Inorganic Chemistry Division.
