The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

RÉSUMÉ

Several methods have been used over the past few years to continuously monitor the elemental pollutants in the flue gases released by industrial processes. The most promising apply spectroscopic detection to an argon inductively coupled plasma (ICP) into which the gas to be analysed is injected. The main problem with these methods concerns their reliability for example, a recent comparison with a reference method using filter sampling has exposed systematic discrepancies. This could be due to deposition phenomena inside the sampling system and to the calibration procedure. The latter procedure generally consists in the nebulization and desolvation of a standard solution to obtain dry aerosols. These aerosols are then carried by pure air and injected into the plasma. A detailed study of the calibration procedure showed that errors can be reduced by ensuring that the composition of the carrier gas is carefully controled to be the same as that of the gas in which the heavy metals are analysed. It is also possible to choose operating conditions that are insensitive to changes in sample gas composition, but the limits of detection are degraded. The ICP technique has been evaluated using two field tests: at a pilot plant for fly ash vitrification, and at a coal-fired power plant. These tests confirm that the control of the gas composition is an essential point, which has not been sufficiently taken into account in the past.
