Based on atomic emission spectroscopy for the analysis of the constituents and their concentrations of samples, the LIBS has been applied in diverse and extensive fields, such as material analysis, environmental monitoring, biomedicine, industrial production control,botany and so on. We considered if the LIBS technique could be used in food detection field. In this chapter, a new approach to identification of Escherichia coli (E.coli) in sausages by means of Laser-induced breakdown spectroscopy is proposed. We identify E.coli in sausage by observing and analyzing the spectral line of sausage, Escherichia coli and sausage charged with E.coli. The results showed the samples were identified obviously by comparing the spectral intensity and varieties of trace mineral elements.

Culham may be just a small town in the English countryside, but it hosts a research facility that might change the world as we know it. The Joint European Torus (JET), based in Oxfordshire, researches how to use fusion energy in daily life. Energy that is environmental friendly, safe and available in almost unlimited quantities. Avantes spectrometers are used to measure changes during these plasma experiments.

For the purpose of space exploration and aircraft technologies, researchers have explored travelling at hypersonic speeds, which entails attaining speeds over Mach 5, more than five times the speed of sound. This puts a huge strain on the aerodynamic and thermal designs of vessels and components. To test components and their capability to withstand airflows at such velocities, the University of Manchester in the United Kingdom have combined their hypersonic wind tunnel with a thermal imaging camera from FLIR Systems.

A new report from FLIR Systems describes how Norwegian waste treatment company - Lindum Ressurs og Gjenvinning AS has successfully implemented a FLIR GF320 gas camera to spot methane leaks, prevent uncontrolled gas venting and keep the air clean at and around its landfill sites. Using the FLIR camera as both a maintenance and safety tool - Lindum has made estimated savings of more than Euro 12,000 per year and has been able to reduce the foul odour nuisance considerably.
