Lab-on-a-Chip Systems: Miniaturized Precision for On-Site Water Quality Testing

Multiparameter sondes are essential tools for comprehensive water quality monitoring across natural, municipal, and industrial water systems. These devices integrate multiple sensors into a single probe, allowing simultaneous measurement of physical, chemical, and biological parameters—such as pH, turbidity, conductivity, dissolved oxygen, and more. Designed for both short-term field sampling and long-term deployments, they offer high-resolution data, minimal maintenance, and robust performance in harsh aquatic environments. Water Quality Instruments, a B2B provider serving clients across North America, delivers a curated line of multiparameter sondes that combine hardware durability, software intelligence, and cloud-based connectivity. Through continuous innovation, deep industry knowledge, and collaboration with strategic partners, we help businesses make faster, more informed water management decisions. Our sondes are ideal for research, compliance, and environmental stewardship, enabling operations to scale efficiently while maintaining data accuracy and system integrity.

Core Components of Lab-on-a-Chip Systems

Hardware

Microfluidic chips made from polymers, glass, or silicon serve as foundational substrates for biochemical assays. These are complemented by Chemical and Gas Sensors for accurate micro-scale chemical detection.

Integrated pumps, valves, and reservoirs for fluid control provide micro-scale actuation and precision handling. Best supported by Peristaltic Pumps from the Chemical & Life Sciences category.

Optical and electrochemical detection modules enhance signal acquisition in diagnostic applications. Integrated with Optical & Imaging Sensors for high-fidelity data collection.

USB or Bluetooth-enabled control units for data acquisition allow local interfacing and hardware automation. These align with BLE Gateways, Beacons & Accessories for low-energy wireless control.
Battery-powered and portable housings for field deployment ensure on-site diagnostic flexibility. Enabled by Portable Power solutions in the Renewable Energy category.

Case Studies

Canada – Moncton, New Brunswick

A municipal water utility incorporated LOC systems to monitor source water for trace metal contaminants during infrastructure upgrades. These compact systems provided rapid diagnostics in the field, enabling crews to respond immediately to potential issues without laboratory delays.

USA – Fresno, California

An agricultural co-op deployed lab-on-a-chip sensors to monitor nitrate levels in irrigation runoff. These sensors enabled real-time nutrient management strategies and compliance with regional water board mandates, supporting more sustainable farming practices. al stability during summer months.

USA – Boulder, Colorado

City technicians implemented LOC devices to conduct rapid, on-site water testing in recreational rivers and creeks. This solution reduced the lag time between sampling and public alerts, helping protect citizens from exposure to harmful pathogens during peak summer usage.
