The Spectrolaser is an elemental analysis instrument based on a
technique called LIBS ( Laser Induced Breakdown Spectroscopy). It incorporates a
high-power laser that induces a bright spark (or plasma) at the surface of the
material being analysed, the light from which is subsequently analysed by a
unique spectrometer and detection system. The elemental fluorescence is directly
related to the concentration of the element in the material being analysed.
Superior analytical features are apparent when the Spectrolaser performance is
compared to other technologies capable of elemental analysis. In particular, it
is sensitive to a wide range of elements present in materials in addition to key
low atomic number elements - such as hydrogen and carbon - which are not
detected by alternative techniques. The low sample preparation required for
analysis enables a high throughput of samples thereby significantly lowering
analysis costs. Analysis times have been reduced to approximately 20 seconds for
simultaneous determination of the concentration levels of all the detectable
elements, which compares favorably to alternative elemental analysis
technologies. |
