“…These methods alone were unsuitable for solid samples (e.g., coal), which led to the development of combustion bomb and pyrohydrolysis methods ( Thomas and Gluskoter, 1974 ; Warf et al., 1954 ) in which a combustion step to release the fluoride is combined with fluoride measurement (e.g., ISE) ( Dressler et al., 2003 ). The combustion methods were later coupled with ion chromatography (IC) and with autosamplers thereafter, allowing the analyst to separate different anions (e.g., fluoride), achieving faster analysis times, and minimizing contamination, using a separate combustion process and offline IC analysis ( Saitoh and Oikawa, 1982 ). The combination of a combustion unit and an attached IC system (combustion ion chromatography [CIC]) has found use in the petroleum and coal industries, where it has been standardized for halogen and sulfur content analysis (e.g., by ASTM International) ( ASTM, 2019 , 2017 ).…”

Summary Combustion ion chromatography (CIC) has found a role in environmental analytical chemistry for fluorine content analysis. It is used for extractable organofluorine (EOF) analysis to evaluate perfluoroalkyl and polyfluoroalkyl substances (PFASs) and other organofluorine burden. The prevailing assumption has been that all PFASs are incinerated in CIC and matrix components have no impact on this process, but this has not been experimentally evaluated. In this work, the combustion efficiencies of 13 different PFASs were determined (66–110%). A notable difference was observed between calibrating the CIC with inorganic fluorine or organofluorine. Potential interferences from cations and coextracted matrix components from whole blood and surface water samples were evaluated. These observations should be acknowledged when performing EOF analysis using CIC, overlooking either non-100% combustion efficiencies or the differences in calibrating the CIC with inorganic fluorine or organofluorine could lead to underestimating EOF content and through that to misguide policy decisions.

“…Hirohara et al (47) © used closed flask combustion for the determination of sulfur in organometallic compounds and added sulfonated sytrene-divinylbenzene resin to the absorbing solution to remove interference from metal ions in the titration of S042 with Ba(C104)2, using thoron I as indicator. Saitoh et al (48) used ion chromatography to determine SCV" after flask combustion.…”

This review follows the last one (I) and covers the period from October 1981 to September 1983. During the later part of 1983 the senior author made a trip to several countries where he previously served as visiting professor and visited a number of laboratories in order to observe the recent developments in organic elemental analysis. It was found that the automated CHN analyzer has become standard equipment, while the manually operated combustion trains are used for checking analytical results which are at variance with the theoretical values or for testing compounds which may explode on combustion. No new instruments were introduced after the publication of the author's comprehensive treatise (2). For the determination of major constituents, reference compounds for C, H, N, 0, Cl, Br, I, F, and S are available (3); thus the analyst can use them for verification of analytical procedures and as calibration standards.The demand for determination of trace elements in organic materials has increased by leaps and bounds lately. Most T. S. Ma Is Emeritus Professor of Chemistry at the City University ol New York where he retired recently after completion of 25 years of service. Professor Ma now divides his time between writing at home in North Carolina and consulting or lecturing abroad. He has written 7 books, 8 chapters In chemical treatises, and 150 research papers. He has lectured In many countries during the past 3 decades. He served twice as Futbright lecturer and once as American specialist with the Bureau of Educational and Cultural Affairs of the State Department. Professor Ma is editor of Mfcrochtmlca Acta, the international Journal on microchemistry and trace analysis. The current interests of Professor Ma are concerned with microchemical Investigation of medicinal plants, organic analysis and synthesis in the milligram to microgram range, and the use of small-scale. Inexpensive equipment to teach chemistry. Professor Ma received the Benedetti-PIchler award In microchemistry In 1978.
