Analysis of high-purity water by flameless atomic-absorption spectroscopy. Part II. Signal integration with a non-resonance line correction system for spurious absorption phenomena
A polychromator has been used in conjunction with a multi-channel integration system and an automatic sample injection unit in graphite-tube flameless atomic-absorption spectroscopy. The precision of the system has been evaluated at high and low absorbances, and its ability to compensate for spurious absorption and variable volatility effects examined.
