Microchip Capillary Electrophoresis for In-Situ Water Analysis, Phase II

Completed Technology Project

Project Description

Microchip Capillary Electrophoresis for In Situ Water Analysis, Phase II
In this Small Business Innovation Research (SBIR) project, Leiden Measurement Technology, LLC (LMT) will develop a portable microfludic analysis instrument for measurement of inorganic ions present in potable water supplies, thermal control system cooling water, and human waste water. A primary goal of the Phase I effort was to identify and demonstrate the most viable development path to advance current state-of-the-art NASA microfluidic analytical instrument technology into a user-friendly, compact, and automated instrument platform for use on the International Space Station (ISS). In this SBIR Phase II effort, LMT will advance current state-of-the-art technologies by developing a Microchip Capillary Electrophoresis (MCE) system with Capacitively-Coupled Contactless Detection (C4D) for the rapid separation, detection and quantification of inorganic ions specified in NASA Spacecraft Water Exposure Guidelines (SWEG). The specific objectives of this Phase I R&D effort are: 1) Development and fabrication of Phase II Microfluidic Chips with Embedded C4D Electrodes for Water Quality Analysis on the International Space Station; 2) Development and fabrication of a Phase II Lock-In-Measurement C4D; 3) Development and fabrication of Phase II MCE Microcontroller and Power Breakout Board; 4) Development of and fabrication of a Phase II MCE High Voltage Board; 5) Verification and validation and end-to-end instrument integration More »
