چکیده انگلیسی
The advantages of using membrane micropumps to introduce sample or standard solutions in flame atomic absorption spectrometry are discussed, using two entirely computer-controlled manifolds which allow a wide range of dispersion coefficients to be obtained. Coupling micropumps to the manifold facilitates calibration graphs to be obtained using a single standard solution. Other advantages include a handy on-line dilution stage for excessively concentrated samples as well as the possibility of obtaining pulsed absorbance-time profiles that once submitted to the Fourier transformation, provide amplitude-frequency plots representing an innovative, not yet fully exploited vision of atomic absorption analytical data.
