Multisyringe Flow Injection Analysis, a Young and Promising Flow Technique

Abstract

Abstract In the present work a brief introduction on multisyringe flow injection analysis (MSFIA) is carried out, including a description of the main characteristics of the system, advantages and inconveniences against other flow techniques, historical evolution and its different ways of performing. Keywords: Multisyringe flow injection analysis, MSFIA. Introduction Since segmented flow analysis, proposed by Skeggs 1 , which can be considered as the first flow technique, different variants have appeared, such as flow injection analysis 2 (FIA), sequential injection analysis 3 (SIA) and multicommuted flow injection analysis 4 (MCFIA) 5 , each of them offering several advantages and inconveniences described in a critical review published in Talanta 6 . The most recent flow technique is the so-called multisyringe flow injection analysis (MSFIA), which was conceived with the aim to compile all the advantages of the former techniques, i.e., sampling rate of FIA, robustness, versatility and reagent saving of SIA, speed of the commutation valves of MCFIA, etc.
