Patent ID: 6992759

Claim:
A sample holder for spectrum measurement settable in a measuring chamber of a spectrophotometer and being used for measuring a spectrum of a liquid sample, said measuring chamber being provided in a way of an irradiation light being emitted from a light irradiating means ( 21 ) to a light detecting means ( 22 ) for spectrum measurement, which comprises a holding block ( 11 ) having a hole ( 111 ) and a light introducing path ( 112 ) being provided crosswise, said the hole ( 111 ) being for holding a sample container ( 30 ) filled with the liquid sample, said the light introducing path ( 112 ) being for introducing the irradiation light for spectrum measurement into the liquid sample held by said hole ( 111 ), said the irradiation light for spectrum measurement being emitted from the light irradiating means ( 21 ) toward the liquid sample held by the hole ( 111 ) by passing through the light introducing path ( 112 ) and reaching to the light detecting means ( 22 ) of the spectrophotometer, a light introducing path position adjusting means ( 12 ) being located under the holding block ( 11 ), said the light introducing path position adjusting means ( 12 ) comprising a light introducing path horizontal direction position adjusting means ( 12 - 1 ) and/or a light introducing path vertical direction position adjusting means ( 12 - 2 ), for adjusting so as to the irradiation light is introduced into the liquid sample by aligning a position of the light introducing path ( 112 ) with a propagating route of the irradiation light for spectrum measurement, when the sample holder for spectrum measurement is set in the measuring chamber of the spectrophotometer, said the light introducing path vertical direction position adjusting means ( 12 - 2 ) adjusting the position of the light introducing path ( 112 ) in a vertical direction relative to the propagating route of the irradiation light for spectrum measurement, said the holding block ( 11 ) further comprising a device for controlling a temperature of said liquid sample.
