Abstract

Maintaining constant pressure is a critical characteristic in many analysis processes. This paper reports a new type of closed-loop micro circulation platform that produces continuous, constant-pressure fluidic circulation, which can be applied to various analytical instruments. The platform contains a circular closed-loop channel that can be deformed by electromagnetic-hydraulic micropumps, thus maintaining, a constant volume and constant pressure of a fluid during circulation. Successful demonstration has been performed to show continuous complete fluid circulation, and it has achieved suppressing pressure-fluctuation by 80% below ±2 Ton- Through the circulatory closed-loop channel (69×4×0.6mm).
