The invention relates to a portable spectrometric analysis system meant to quickly perform an in situ analysis of the concentration of sampled solutions and also to determine the concentrations specific to the flow injection analysis. According to the invention, the system consists of a portable spectrometric structure comprising some measuring tongs which have two clamping dies () and two pressing arms (), a pressing spring (), a pin (), a radiation optical fiber (), a total-reflection miniature mirror (), a collimating lens () and a focusing lens (), a receiving optical fiber (), a miniature spectrometer () with fixed diffraction grating and diode array detector, an UV-VIS-NIR radiation source () provided with a drum () with filters for the quantitative chemical analysis and a portable computer unit () ensuring both the acquisition, processing and display of data and the electrical supply of the miniature spectrometer () and also of the radiation source () through the voltage of USB interface. |
