Sample receptacle for spectrophotometry

Abstract

Described herein is a receptacle for holding a sample under spectrophotometer analysis comprising: a body, first and second opposing windows separated by a gap to provide a volume for a sample, wherein at least the first opposing window is supported by a first compliant member, and wherein under a force, the first compliant member allows positioning of the first opposing window relative to a first datum to set a desired: a) gap between the first and second opposing windows, and/or b) relative orientation of the first and second opposing windows.

1 . A receptacle for holding a sample under spectrophotometer analysis comprising:
 a body   first and second opposing windows separated by a gap to provide a volume for a sample, wherein at least the first opposing window is supported by a first compliant member, and   wherein under a force, the first compliant member allows positioning of the first opposing window relative to a first datum to set a desired: a) gap between the first and second opposing windows, and/or b) relative orientation of the first and second opposing windows.   
     
     
         2 . A holder for receiving receptacle for holding a sample under spectrophotometer analysis, wherein
 the receptacle comprises: a body, and first and second opposing windows separated by a gap to provide a volume for a sample, wherein at least the first opposing window is supported by a first compliant member, and   wherein the holder is operable to provide a force to the receptacle such that the first compliant member allows positioning of the first opposing window relative to a first datum to set a desired a) gap between the first and second opposing windows, and/or b) relative orientation of the first and second opposing windows.   
     
     
         3 . A receptacle for holding a sample under spectrophotometer analysis comprising:
 a compliant support for first and second windows   an opening in the support, and   first and second windows on the support forming a volume with the opening,   wherein under a force, the compliant support allows positioning of at least the first window relative to a first datum to set a desired a) gap between the first and second windows, and/or b) relative orientation of the first and second windows.
