Challenge: Creating an Active Fluid Control System for a Disposable Water Quality Test

Presenting a challenge to the ALine Engineering Team, the client needs a disposable system which manages the downstream metering mixing of the concentrated water sample and its subsequent delivery to the sensor for testing.

To solve this challenge, the team needs to integrate multi-step workflow into a single use cartridge appropriate for se with a backpack-based instrument system.

Solution: Successful Application!

The devices developed, uses pneumatically controlled valves coupled with a rugged instrument interface to perform binding assays. Additionally, semi-automated control is used to perform all steps the assay requires (volume metering, mixing, capture, washing, detection).
