Measuring more metals

Andover, MA-based Physical Sciences is developing a multi-metals emission monitoring system based on the company’s spark-induced breakdown spectroscopy (SIBS) technology.

Andover, MA-based Physical Sciences has been awarded a research contract from the US Environmental Research Agency to develop a multi-metals emission monitoring system based on the company’s spark-induced breakdown spectroscopy (SIBS) technology.

Prior work has shown that PSI’s SIBS technology is capable of sensitively monitoring metals in airborne particles that have atomic emissions in the visible portion of the spectrum – lead, chromium and cadmium, for example.

PSI is now developing SIBS detection in the deep ultraviolet to make the technology useful for measuring all of the hazardous air pollutants (HAPs).

The advanced SIBS will be capable of monitoring arsenic and selenium, which have strong emissions features in the ultraviolet.

This feature will then be married to the existing SIBS system to creae the basis of a monitor that is able to identify and quantify all metallic HAPs.

Once complete, PSI’s monitor will enable incinerators and power plants to monitor all their emissions in real time.
