Abstract:

A sequentially controlled valving system for the solid phase extraction (SPE) process on Lab-on-CD platform was designed, fabricated, and tested. The fabrication of the system was done with 3D printing technology. The centrifugal force provided the driving force needed for the fluidic control. The sample flow was driven from the central area of the disc to move outward to the edge by centrifugal force. The valving system was passive, and each valve could be switched at a certain rotating frequency. As a result, only one micro-motor was needed to drive the flow and control the valving system. This design is based on preliminary results of a significant amount of research which demonstrated that centrifugal instrumentation is highly reliable, significantly better than existing technologies and that sequential control of multiple valves and inward-pumping can be used for the proposed lab-on-a-CD system for separation and detection of oil detection.
