The Chemistry Department at the College of Education for Pure Sciences organized a training course on flow injection technology. The course was presented by Asst. Prof. Dr. Jahan Hamid Abdul Amir, Asst. Prof. Dr. Adel Abbas Karim, and Asst. Prof. Dhiaa Mohammed Hassan. The course aimed to introduce participants to flow injection analysis (FIA), an accurate, rapid, and inexpensive chemical analysis method used to determine the concentration of substances in liquid samples. This technique relies on injecting a small amount of the sample into a flowing stream of solvent or reagent, then measuring the chemical reaction between the sample and the reagent. The course also included several topics on the operating principle and components of the flow injection system, the advantages of flow injection technology, an explanation of the difference between using flow injection technology and traditional analysis, and the applications of flow injection technology. Researchers have recommended the need to pay attention to such topics because the use of flow injection technology is of great importance, as it provides accurate results and is economically feasible because it is low-cost compared to traditional analysis. Furthermore, the availability of this technology in laboratories provides high flexibility in analyzing a wide range of chemicals in a short period of time.
