Resumo (PT): Nowadays, the trend towards more compact, smarter and simpler devices is generally recognized as one of the most challenging aspects in the development of analytical instrumentation. Modern flow-based procedures do not escape this tendency. The level of integration and automation and the operational functionality of Multi-pumping flow systems (MPFS) would, in most of the situations, meet this requirement. The essential elements of MPFS are multiple solenoid actuated micro-pumps strategically positioned in the flow manifold, which are accountable for solutions insertion, propelling and commutation, conditioning the establishment and subsequent detection of the reaction zone. Being the only active components of the flow manifold they provide a great operational simplicity and assure a straightforward run-time control of important analytical variables. Moreover, the reduction of active components minimizes the probability of occurrence of equipment failures, malfunctions or errors. The low size and low cost of solenoid micro-pumps make them ideal tools to build up compact environmentally friendly analytical systems, which are characterized by low solutions consumptions and the minimisation of hazardous waste generation. Furthermore, the reproducible pulsed flowing stream produced by micro-pumps actuation has proven to be a valuable feature regarding sample/reagent mixing and reaction zone homogenisation. <br> <br> Keywords: Multi-pumping flow system; Solenoid micro-pumps; Pulsed flow; Flow analysis <br> <a target="_blank" href="http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6TF4-4MW322B-1&_user=2460038&_coverDate=09%2F26%2F2007&_rdoc=8&_fmt=high&_orig=browse&_srch=doc-info(%23toc%235216%232007%23993999998%23669471%23FLA%23display%23Volume)&_cdi=5216&_sort=d&_docanchor=&_ct=38&_acct=C000057398&_version=1&_urlVersion=0&_userid=2460038&md5=2c21cd6d12be84c35d4356de4af1c51a"> Texto integral</a> <br> <br>
