| 摘要 |
The present invention pertains to an instrument for the automated thermal treating of liquid samples, comprising a temperature-controlled receptacle for receiving a plurality of vessels for containing said samples in thermal communication therewith, a detection module equipped with a detection arrangement provided with one or more detectors for detecting light emitted from said samples and a coupling arrangement provided with a plurality of optical fibers for transmitting said emitted light to said detection arrangement, wherein said optical fibers have first and second end portions, said first end portion and said second end portion of each optical fiber being fixed with respect to each other, and a moving mechanism for moving said coupling arrangement and/or said receptacle in a manner to vary an inter-distance between said coupling arrangement and said receptacle so as to allow the vessels to be loaded to or unloaded from said receptacle and to enable detection of light from samples contained in said one or more receptacle-loaded vessels. It further pertains to a method for the automated thermal treatment of liquid samples comprising a step of varying an inter-distance between a temperature-controlled receptacle for loading with a plurality of vessels for containing said samples and end portions of optical fibers, wherein said receptacle is configured to form a thermal communication with said loaded vessels and wherein said optical fibers have first and second end portions, said first end portion and said second end portion of each optical fiber being fixed with respect to each other for transmitting light, said variation of said inter-distance allowing the vessels to be loaded to or unloaded from said receptacle and to enable detection of light from said samples contained in said one or more receptacle-loaded vessels. |
