PROBLEM TO BE SOLVED : To provide a flameless atomic absorption photometer, which simultaneously executes improvement of rare-earth element measuring sensitivity by suppressing carbide generation in an atomization furnace and exact correction of backgrounds.
SOLUTION : The flameless atomic absorption photometer comprises : a cylindrical atomization furnace made of graphite; a sample tray fixed inside thereof that is made of metal having a melting point of at least 2800°C or more and that has paramagnetism; a right electrode and a left electrode provided at respective ends of the cylindrical atomization furnace for atomizing a sample; and a gas flow channel for introducing a gas provided in the inside of the right electrode and the inside of the left electrode into the atomization furnace. The sample tray includes a dish-shaped portion where a sample is dropped.
