ISE has again raised the environmental bar to new levels by adding Mass Spectrometry to our list of in-house air quality monitoring services. Our SRS UGA300 mass spectrometer also allows our research staff to expand its investigative research capabilities down to the atomic level.

With the ability to detect materials having weights up to 300 atomic mass units (AMU's), and rapidly compare test samples against 192,262 different chemical compounds using the NIST08 Mass Spectral Library database search program, the use of mass spectrometry allows ISE to quantify with great accuracy test samples for heavier and more difficult to detect elements and compounds such as lead, mercury, arsenic, as well as radioactive gasses such as Radon.

Featured Video Clip (Shock Wave)

A video taken by ISE showing the supersonic expansion of high pressure natural gas in a pipeline. 

The shock wave is clearly visible at the 1:00 min mark as a white cloud above the end of the pipe and produces an acoustic overpressure of close to 140 dB - which is as loud as a rocket engine.
