METHOD OF ATOMIC ABSORPTION ANALYSIS AND ATOMIC ABSORPTION PHOTOMETER

摘要

Provided is an atomic absorption photometer with which a liquid measurement sample injected into a graphite tube is dried in a pre-measurement stage, wherein it is possible to determine whether the drying has been properly executed, and wherein a targeted measurement sensitivity and measurement reproducibility are provided with a minimum number of measurements and without many repetitions of measurement. The present invention comprises finding the absorbance of reference light, which is a component perpendicular to a magnetic field in light transmitted through a heating section, and determining there to be bumping of a sample if the duration of time where the absorbance of the reference light is greater than a predetermined value is within a predetermined duration of time; or alternatively finding the absorbance of sample light, which is a component parallel to a magnetic field in light transmitted through the heating section, and the absorbance of reference light, which is a component perpendicular to the magnetic field in light transmitted through the heating section, and determining there to be bumping of a sample if a corrected absorbance obtained by subtracting the reference light absorbance from the sample light absorbance is greater than a predetermined value.
