Surface Plasmon Resonance (SPR)

An innovative technology to detect arsenic in water is Surface plasmon resonance,SPR.

Working principle of a single beam SPR:

A light source will shone on the prism with a sensor chip attached on its surface, buffer will then flow through the prism .Hence, reflecting the light onto the mirror in a critical angle, where readings are taken down

Comparison of SPR with other analysis methods:

As compared to other analysis technologies, SPR can detect a smaller quantity of arsenic compound , making it more precise then other detection method,but high cost for this technology has offset its benefits.
