Abstract
On a analytical device for photometric analysis of chemistry and/or fluid samples comprising a rotatable disk-like body (1) a plurality of receptacles (7) for fluid samples and optical means (9) for guiding light beams through the receptacles are arranged. At least part of the optical means (9) are designed and/or arranged such that at least part of the light beams is deflected and guided through the receptacles at an angle to the radially outward direction on the disk-like body (1) which means at an angle to the radius, connecting the respective optical means with the rotation axis (3) of the disk-like body (1).
Claims15
An analytical device for photometric analysis of a biological sample, the device comprising a rotatable disk-like body with a receptacle for the biological sample and optical means for guiding a light beam through the receptacle, wherein the optical means is arranged such that the light beams is firstly deflected and guided through the receptacle at an angle to the radially outward direction on the disk-like body and is secondly deflected after the passage through the receptacle out of the plane of the disk-like device.
An analytical process for photometric analysis of a fluid biological sample arranged on a rotatable disk-like body with a receptacle for the fluid sample wherein a light beam is first guided by optical means arranged on the disk-like body through the receptacle in a direction which is at an angle to the radially outward direction of the rotatable disk-like body or the radially outward directed rotation force respectively, the light beam after passage through the receptacle is deflected out of the plane of the disk-like body, and the partial absorption of the light beam guided through the receptacle is used for analytical purpose.
