“…The study included the examination of various blowing agents, catalysts, and carbonific materials, singularly and in formulated coatings. Using an ion-exchange column, the series from benzoic to benzene-hexacarboxylic acids were separated by HELC (7) HELC method (36) for the determination of phthalate esters was reported. This study included the analysis of organic mercury compounds, making use of a multiple detection system consisting of refractive index (RI), UV, and flame ionization detectors.…”

This review includes analytical methods of coating interest that have appeared in the literature since the last published survey (112), or were not included in the previous review, and it covers the literature through November 1974. Some selectivity has been exercised to include only those procedures especially pertinent or those, which in the authors' judgment could be adapted easily to analytical coating problems.A number of books on various phases of coating analysis have been published in this two-year period. In previous years, ASTM Standards on paint were included in parts 20 and 21 of the "Annual Book". However, in 1974, all of the ASTM standards on paint and related products were published in volumes 27-29. Part 27 ( 4 ) contains 190 standards of which 37% are new, revised, or changed in status. Part 28 (5) contains 140 standards of which 24% are new, revised, or changed in status. Among the new standards in this volume are a recommended practice for qualitative identification of polymers in emulsions, chemical analysis of phthalocyanine blue and green pigments, and analysis of white zinc pigments. Volume 29 ( 6 ) includes 240 standards, 12% which are new, revised, or changed in status, and contains a new test for aromatics in mineral spirits by gas chromatography (GC).Haken's book, (41), "Gas Chromatography of Coating Materials," covers the GC analysis of a broad range of raw materials and finished coatings. Litchfield published a monograph (62) describing the chromatographic analysis of triglycerides. A book by Crippen (25) emphasized the combination of organic functional group analysis along with GC retention data and solubility studies for the identification of organic compounds, many being of coatings significance. "Experiments in Polymer Science" (21 ) contained experiments for determining molecular weight distribution, morphology, and thermal properties of polymers. Haslam et al. (48) published a second edition of "Identification and Analysis of Plastics." This edition contains a new 80-page chapter entitled, "Instrumentation Methods"; the remaining chapters are similar to those in the first edition. "Gas Chromatography in the Chemistry of Polymers" (10) covered fundamentals of GC, monomer, and solvents analysis. Other chapters deal with kinetics and reactions of high polymer formation, and the determination of unreacted monomers, pyrolytic GC, and the analysis of additives. The GC analysis of terpenes was described in "Advances in Chromatography'' by Giddings and Keller (37).During the period since the previous Coatings Review, very significant advances have been made in high-efficiency liquid chromatography (HELC) using controlled flow at high pressure, continuous detection, and small particle size column packing material. The modes of separation are based on adsorption, partition, ion-exchange, and molecu-Authors have not been supplled with free reprints for free distribution.

“…lar size separations or gel-permeation chromatography (GPC). The intense interest in HELC is reflected by the large number of articles described in other sections for polymers (9,20,22,29,30,107,109), oils and fatty acids (33,47,49,76), aromatic acids (7,82), plasticizers (36), and pigments (104).…”
