Abstract

The present invention provides for methods and apparatus for locating a capillary channel (110) that is disposed within a lab chip. The method provides for scanning the channel with a light source (106), monitoring the resulting light at the edges (114, 116) of the lab chip, and interpreting this information whereby the light detected at the edges of the lab chip can be used as a means for characterizing the location of the side walls of the channel within the lab chip. The apparatus provides for a carriage system to which a light source and the lab chip are attached. It also provides for one or more scatter detectors (102, 104) directed towards the edges of the chip and connected to a computer processor (118) for purposes of analysis.
