    Abstract: A method is used to determine an absorption behavior of a medium. The method includes establishing an absorption coefficient of the medium using a first intensity value and at least one second intensity value and a length different between a first measurement distance and a second measurement distance. The first intensity value represents a measured first light intensity after passing over a first measurement distance in the medium. The second intensity value represents a measured second light intensity after passing over a second measurement distance in the medium. The first intensity value and the second intensity value are measured using light with a common initial intensity.

    Abstract: A closed path infrared sensor includes an enclosure, a first energy source within the enclosure, at least a second energy source within the enclosure, at least one detector system within the enclosure and a mirror system external to the enclosure and spaced from the enclosure. The mirror system reflects energy from the first energy source to the at least one detector system via a first analytical path and reflects energy from the second energy source to the at least one detector system via a second analytical path. Each of the first analytical path and the second analytical path are less than two feet in length.

    Abstract: Disclosed is a sample element for use in analyzing a concentration of an analyte in a material sample. The sample element comprises a sample chamber having at least one window, and a supply passage extending from the sample chamber. The supply passage defines a supply axis. The sample element further comprises a vent opening in fluid communication with the sample chamber. The vent opening is offset from the supply axis as the sample element is viewed orthogonal to the window.

    Abstract: An apparatus and method are provided for measuring the hematocrit level of blood. The presently preferred embodiment comprises a light emitting device which emits an amount of light into a blood sample. This light travels through the blood sample to two light detecting devices positioned relative to the light emitting device in a predetermined geometry such that light emitted from the light emitting device must travel farther to reach one of the light detecting devices than to reach the other, thereby forming a light path from the light emitting device to one light detecting device which is longer than the path from the light emitting device to the other light detecting device. According to the present invention, the amount of light detected by one of the light detecting devices is regulated so that the amount of light detected is constant. Thereafter, the amount of light detected by the unregulated light detecting device is a linear representation of the hematocrit of the blood in the blood sample. The hematocrit sensor may be used within a plasma separator apparatus wherein the hematocrit measurement regulates the operating parameters of the autotransfusion system to maintain the hematocrit of the blood within a predetermined range.
