Description

This item was taken from the IEEE Conference ' Wireless control of microchip capillary electrophoresis with a mobile platform ' We report the design of a digital system to wirelessly control microchip capillary electrophoresis (CE) equipment and a mobile unit for chemical analysis. The digital system consists of an embedded processor designed for digital control, decoding and applying of wirelessly-transmitted test parameters, data acquisition, and mobility control. The design is implemented on a field programmable gate array (FPGA) and its development board interfaces with four digital-to-analog converters on a newly-designed 3-channel high voltage power supply, electrochemical detector, wireless modems for communications with a base unit, mobile platform motor controllers, GPS sensor, and a micropump. The FPGA allows for all the interfacing hardware to perform CE and transmission of the data acquired from the interfacing electrochemical detector.
