In this paper, the fabrication of a wireless mobile unit containing an electrochemical detection module and a 3-channel high-voltage power supply (HVPS) designed for microchip CE is described. The presented device consists of wireless global positioning system controlled robotics, an electrochemical detector utilizing signal conditioning analog circuitry and a digital feedback range controller, a HVPS, an air pump, and a CE microchip. A graphical user interface (LabVIEW) was also designed to communicate wirelessly with the device, from a distant personal computer communication port. The entire device is integrated and controlled by digital hardware implemented on a field programmable gate array development board. This lab-on-a-robot is able to navigate to a global position location, acquire an air sample, perform the analysis (injection, separation, and detection), and send the data (electropherogram) to a remote station without exposing the analyst to the testing environment.
本文描述了一种无线移动单元的制造，该单元包含一个电化学检测模块和一个为微芯片毛细管电泳设计的三通道高压电源（HVPS）。所展示的设备由无线全球定位系统控制的机器人、利用信号调节模拟电路和数字反馈范围控制器的电化学检测器、一个HVPS、一个气泵以及一个毛细管电泳微芯片组成。还设计了一个图形用户界面（LabVIEW），以便从远程个人计算机通信端口与该设备进行无线通信。整个设备由现场可编程门阵列开发板上实现的数字硬件进行集成和控制。这种机器人实验室能够导航到全球定位位置，采集空气样本，进行分析（进样、分离和检测），并将数据（电泳图）发送到远程站，而无需让分析人员暴露在测试环境中。
