Abstract
In un spettrometro di assorbimento atomico, un considerevole ampliamento dell'intervallo di misurazione dinamico viene conseguito provvedendo una sorgente di radiazione che produce contemporaneamente le linee di emissione 253,7 e 184,9, facendo incidere questa radiazione, attraverso il campione sottoposto a misurazione, contemporaneamente su due trasduttori elettroottici, dei quali il primo trasduttore è sostanzialmente sensibile alla linea di emissione a 253,7, e l'altro è essenzialmente sensibile alla linea di emissione e 184,9 nm. Con ciò, è possibile realizzare un intervallo di misurazione complessiva che copre 4 ordini di grandezza.(Figura 1).In an atomic absorption spectrometer, a considerable expansion of the dynamic measurement range is achieved by providing a radiation source that simultaneously produces the emission lines 253.7 and 184.9, making this radiation incised, through the sample under test, simultaneously on two electro-optical transducers, of which the first transducer is substantially sensitive to the emission line at 253.7, and the other is essentially sensitive to the emission line and 184.9 nm. With this, it is possible to achieve an overall measurement range covering 4 orders of magnitude (Figure 1).
