1. A sample cell for retaining a fluid sample, the sample cell comprising a handle and parallel plates;
- the parallel plates being coupled to the handle;
the parallel plates being spaced at a distance and defining a cavity;
the cavity being open on at least three sides;
the distance between the plates allowing capillary action to draw and retain a fluid sample in the cavity.

Abstract
A sample cell for retaining a fluid sample comprising a handle and parallel plates. The parallel plates are coupled to the handle and are spaced at a distance thereby defining a cavity which is open on at least three sides. The distance between the plates allows capillary action to draw and retain a fluid sample in the cavity. Methods of using the sample cell are also disclosed.

17. A method of determining an optical property of a fluid sample, the method comprising:
-
providing a sample cell comprising two parallel planar plates defining a sample space open on at least three sides, wherein the distance from one planar plate to the other planar plate is selected to permit the fluid sample to enter through an open side and be retained in the sample space by capillary force;
contacting the sample cell with a fluid sample and drawing fluid sample into the sample space;
deforming the sample device by applying one or more clamps to the deformable regions thereby selecting a distance between the first plate and the second plate and defining the volume of a measurement zone;
placing the sample cell into a device for determining the optical property of the sample in an orientation such that the light path passes through the measurement zone; and
determining an optical property of the fluid sample. - View Dependent Claims (18, 19, 20, 21, 22)
