Chip makes pH measurements easier and devices more robust and portable

Fraunhofer Institute for Photonic Microsystems IPMS has developed a new technology that makes pH measurements significantly more robust, simple, and reliable. Instead of the traditional, often error-prone reference electrodes, a durable chip is now used. This chip can be stored dry, is pressure-resistant, and easily integrated into compact devices. Initial test kits are already available for rapid use in medical, biological, agricultural, and environmental applications.
