The invention relates to a portable electronic spectrometric system for determining the chemical composition and the concentration of a liquid solution and for an accurate volumetric dosage thereof. According to the invention, the system comprises a flowing and spectrophotometry cell consisting of a body (5) having a cylindrical flow channel (c) provided at its ends with two connections (r1 and r2) for fastening a syringe needle and an intake/discharge syringe (7), respectively, or an electronic dosage dispenser, as the case may be, which is connected, by some short optical fibers (9 and 8) and some long optical fibers (3 and 4), to a source of polychromatic radiation (1) provided with a set of interchangeable optical filters (2), and to a spectrometer (10) provided with a Diode-Array detector which communicates with a computer system (11) to analyze an unsettled solution, the flowing and spectrophotometry cell being provided with a disposable encapsulated filter (12) . Invenţia se referă la un sistem spectrometric electronic portabil, pentru determinarea compoziţiei chimice şi a concentraţiei unei soluţii lichide, şi dozarea volumetrică precisă a acesteia. Sistemul conform invenţiei este format dintr-o celulă de curgere şi spectrofotometrare, compusă dintr-un corp (5) având un canal (c) cilindric de curgere, prevăzut la capete cu două racorduri (r1 şi r2), pentru fixarea unui ac de seringă şi, respectiv, a unei seringi (7) de aspiraţie/refulare, sau, după caz, a unui dispenser de dozare electronic, conectată, prin intermediul unor fibre optice (9 şi 8) scurte şi al unor alte fibre optice (3 şi 4) lungi, la o sursă (1) de radiaţie policromatică, echipată cu un set de filtre (2) optice interschimbabile şi, respectiv, la un spectrometru (10) echipat cu detector Diode-Array, care comunică cu un sistem de calcul (11), pentru analizarea unei soluţii tulburi, celula de curgere şi spectrofotometrare fiind prevăzută cu un filtru (12) capsulat, de unică folosinţă.
