Abstract:
A sample cell apparatus for use in spectroscopic determination of an analyte in a body fluid sample includes a first plate member and a second plate member made from an optically clear material. A channel extending into a surface of the first plate member and an opposing surface of the second plate member houses a floating seal, which surrounds a fluid sample chamber. The fluid chamber is closed to define a repeatable optical path-length therethrough by urging the first plate member against the second plate member without compressing the floating seal between the first plate member and the second plate member. The seal channel is vented to prevent fluid pressure from flexing the first plate member or the second plate member. An actuator having an extended foot portion extends over the fluid chamber to help prevent flexing of the first plate member or the second plate member.

Claim (Index 9):
A method for spectroscopic determination of an analyte in a body fluid sample, the method comprising:\n providing a sample cell having a sample path extending between a first plate member and an opposing second plate member, wherein the sample path is adapted for communicating the body fluid sample from a fluid inlet path through a sample chamber between the first plate member and the second plate member to a fluid outlet path; providing one or more spring members between the first plate member and the second plate member, wherein the spring members apply a spring force configured to separate the first plate member from the second plate member; moving the first plate member along a normal axis of the first plate and the second plate to a closed configuration by applying a compressive force that overcomes the spring force and urges an abutment surface of the first plate member against an abutment surface of the second plate member, wherein in the closed configuration a predetermined optical path length is provided through the sample chamber for conducting optical measurements; providing a floating seal member in a seal channel surrounding the sample chamber; and preventing the first plate member from flexing over the sample chamber while applying the compressive force by allowing a fluid to vent through a vent port in the seal channel and by applying the compressive force to an area of the first plate member that extends over the sample chamber.
