Data collected to analyze the burst frequency of each valve tested to achieve accurate sequential control of micro-valving system.

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.

针对光盘式实验室（Lab-on-CD）平台上的固相萃取（Solid Phase Extraction, SPE）流程，本研究设计、制备并测试了一款时序控制阀门系统。该系统采用3D打印技术完成制备，以离心力作为流体控制所需的驱动力。样品流在离心力作用下从圆盘中心区域向外流动至边缘，该阀门系统为被动式，每个阀门可在特定旋转频率下完成切换。因此仅需一台微型电机即可驱动流体并控制阀门系统。本设计基于大量研究的初步成果，这些研究证实离心式仪器具有极高的可靠性，且显著优于现有技术；同时证明多阀门时序控制与向内泵送技术可应用于所提出的光盘式实验室系统，用于溢油的分离与检测。相关数据集可通过GRIIDC唯一数据集标识符（Unique Dataset Identifier, UDI）R6.x831.000:0003获取（DOI: 10.7266/n7-g8hx-e455）。本数据集支持以下发表成果：Zhang Y、Xiang J、Wang Y、Qiao Z及Wang W于2019年发表的《用于水中溢油固相萃取与荧光检测的3D打印离心微流控平台》，刊载于《微流控、生物微机电系统与医用微系统XVII》，DOI: 10.1117/12.2515719。
