Summary:The invention relates to an analysis device (1) comprising: a tight analytical circuit (3) comprising an injection loop (BI), at least one mixing loop (BM), and a turbidimetry analysis means (CD), a liquid being able to continuously circulate through the injection loop, the mixing loop and the analysis means; a means (IL) for injecting said liquid into said injection loop and a means for removing said liquid from a source (S); a means (ISR) for injecting, into said injection loop, a solution for displaying sulfates in said liquid by means of turbidimetry; and a means (ISP) for injecting a rinsing solution, comprising a peristaltic pump (PPB)and a system (VF, VG) of valves placed between the pump (PPB) and said injection loop. The invention is especially applicable in fields of the offshore oil industry. La présente invention se rapporte à un dispositif (1) d'analyse comprenant : un circuit analytique (3) étanche comprenant une boucle d'injection (BI), au moins une boucle de mélange (BM), et un moyen d'analyse par turbidimétrie (CD), la boucle d'injection, la boucle de mélange et le moyen d'analyse pouvant être parcourus en continu par un liquide; un moyen d'injection (IL) dudit liquide dans ladite boucle d'injection et un moyen de prélèvement dudit liquide à partir d'une source (S); un moyen d'injection (ISR) dans ladite boucle d'injection d'une solution de mise en évidence de sulfates dans ledit liquide par turbidimétrie; et un moyen d'injection (ISP) d'une solution de rinçage comprenant une pompe péristaltique (PPB) et un système de vannes (VF, VG) placées entre la pompe (PPB) et ladite boucle d'injection. La présente invention trouve notamment des applications dans les domaines de l'industrie pétrolière offshore.
