1. An apparatus comprising:
- a body comprising;
a first opening located at a first end;
a second opening located at a second end;
two planar inner surfaces, andtwo planar outer surfaces, said two planar outer surfaces being substantially parallel to said two planar inner surfaces;
at least a portion of at least one inner surface and its corresponding outer surface being at least partially transparent;
an inner space of said body connecting said first opening and said second opening, providing a passage from said first opening to said second opening; and
said two planar inner surfaces forming two planar and parallel sides of at least a portion of said passage, said portion of said passage being dimensioned to hold a liquid sample within said portion of the passage by capillary action and forming a measurement region with a predetermined optical pathlength.

19. A method for measuring an optical property of a liquid sample, comprising the steps of:
-
providing an apparatus having a body comprising; a first opening located at a first end; a second opening located at a second end; two planar inner surfaces, and two planar outer surfaces, said two planar outer surfaces being substantially parallel to said two planar inner surfaces; at least a portion of at least one inner surface and its corresponding outer surface being at least partially transparent; an inner space of said body connecting said first opening and said second opening, providing a passage from said first opening to said second opening; and said two planar inner surfaces forming two planar and parallel sides of at least a portion of said passage, said portion of said passage being dimensioned to hold a liquid sample within said portion of the passage by capillary action and forming a measurement region with a predetermined optical pathlength; placing the measurement area of the apparatus in a positional relationship to a light source and detector of an optical detection device such that a light path is provided from the light source through the measurement area, to the optical detection device, wherein the measurement area of the apparatus holds the liquid sample. - View Dependent Claims (20, 21, 22, 23)
