Major advance in qualitative analysis
The elemental composition of metals can be analysed instantly using
Ocean Optics’ new spectrometer systems. The Laser-induced Break-down Spectrometer (LIBS) systems are real-time, high resolution, portable instruments capable of analysing practically every known element in gas, liquid or solid samples with a sensitivity of parts per billion. Applications in the wire and
cable industry include semi-conductor analysis, blast-furnace monitoring and chemical contamination in solids, liquids or gas.
A complete LIBS scan can be executed in less than a second, saving time and making it possible to analyse transient samples. Only trace amounts of a sample are required for analysis, minimising sample preparation. LIBS systems can be used in the laboratory, in the field or remotely, and on any sample geometry. A single pulse from a high-intensity laser is focused on the sample area, exciting the sample and creating plasma, into which a trace amount of the sample has been ablated. As the plasma decays, excited elements in it emit light at wavelengths that
are distinct to each element. This light is collected by a probe and sent to a high-resolution, multi-spectrometer system for analysis.
LIBS systems come with intuitive operating software that enables automatic identification of all elements present in the sample. Other features allow tracking emission intensities over multiple scans and correlation of analysis routines.
