<p>PROBLEM TO BE SOLVED: To provide an uninterruptible power supply apparatus of small capacity at a low cost while ensuring the continuous operation of a sample analyzer even when any momentary power failure at a predetermined level occurs in an AC power source. SOLUTION: In the sample analyzer for analyzing a sample 4, a power source stabilizing means 14 for stabilizing the DC voltage by converting the AC power source for operating the analyzer 1 into the direct current is provided on an irradiation source 2 or a part of apparatuses 21 and 22 including an excitation source for the sample 4, and the remaining apparatuses are connected to the AC power source via the uninterruptible power supply apparatus 13. The sample analyzer further comprises a momentary power failure detection circuit 15 for detecting any momentary voltage drop of the AC power source and a momentary power failure occurrence displaying means 16 for displaying generation of any momentary voltage drop of the AC power source based on the detection by the momentary power failure detection circuit 15.</p> |
