Abstract

An air-driven shutter device (30, 120) is disclosed for, in or used in an optical analyzer (100, 140). The optical analyzer (100, 140) includes a measurement field (95) to which sample (S) is supplied, a light-emitting unit (50) for emitting measuring light to the sample (S) in the measurement field (95), a light-receptive unit (51) for receiving the measuring light that has passed through the sample (S), and a purge air supplying unit (56) for supplying purge air (PA). The air-driven shutter device (30, 120) includes a shutter (32) and a shutter opening and closing mechanism (132). The shutter (32) is disposed between the light-emitting unit (50) and/or the light-receptive unit (51) and the measurement field (95). The shutter opening and closing mechanism (132) keeps the shutter (32) open with pressure of the gas supplied from the purge air supplying unit (56) , and closes the shutter (32) when the pressure of the gas supplied from the purge air supplying unit (56) becomes lower than a predetermined level.
