TEST SYSTEM AND METHOD

摘要

The present invention relates to an apparatus for detecting compounds, the apparatus having a device defining a disk-shaped geometry, the device having a centre, a plurality of fluid channels each comprising a fluid inlet positioned at a first distance from the centre and a fluid channel end at a second distance from the centre, the second distance being larger than the first distance, one or more sensors arranged at each fluid channel, wherein the sensors each comprise at least one optical detectable member, the test apparatus further comprising one or more optical sensing devices arranged for sensing the at least one optical detectable member of the one or more sensors, and a rotation device adapted for rotating the device so that the sensors pass over the one or more optical sensing devices. Further the present invention relates to a method for determining compounds comprising providing an apparatus for detecting compounds having a device defining a disk-shaped geometry, the device having a centre, a plurality of fluid channels each comprising a fluid inlet positioned at a first distance from the centre and a fluid channel end at a second distance from the centre, the second distance being larger than the first distance, one or more sensors arranged at each fluid channel, wherein the sensors each comprise at least one optical detectable member, the test apparatus further comprising one or more optical sensing devices arranged for sensing the at least one optical detectable member of the one or more sensors, and a rotation device adapted for rotating the device so that the sensors pass over the one or more optical sensing devices, the method comprising: providing a fluid at an inlet near the centre of the device, rotating the device, and obtaining properties of the sensors using the optical sensing devices.
