X-ray fluorescence spectrometer, information storage medium, and program

A non-transitory computer-readable information storage medium having stored thereon a program to be executed by a computer used for an X-ray fluorescence spectrometer,

• the X-ray fluorescence spectrometer including:
• a sample chamber in which a sample is to be arranged;
• an irradiation chamber divided from the sample chamber by a partition wall partially including a partition film which transmits X-rays, the irradiation chamber having arranged therein an X-ray source configured to emit X-rays to the sample via the partition film;
• and
• the computer,
• the program causing the computer to execute:
• a measurement condition acquisition step of acquiring a measurement condition including a measurement time;
• a step of calculating, based on the measurement time included in the acquired measurement condition, a predicted continuous irradiation time predicted as a time for which the partition film is irradiated with the X-rays through measurement performed in accordance with the measurement condition;
• an irradiation time acquisition step of acquiring an irradiation time for which the partition film is irradiated with the X-rays;
• and
• a protection control step of performing protection control of protecting the partition film from irradiation with the X-rays based on the irradiation time acquired in the irradiation time acquisition step and the predicted continuous irradiation time.
