SciAps presented new analyzer LIBZ

The Z is based on a well-established technology called laser induced breakdown spectroscopy (LIBS) or LIBZ as we like to call it. With LIBS, a laser is fired at a sample, heating it almost instantaneously and creating an electron plasma. As the plasma cools after about 1 us, the electrons return to the atoms that constitute the sample, emitting light at various discrete wavelengths. The spectrometer resolves the wavelengths and the processor determines elements present and concentrations.

LIBZ is an optical technique, not x-ray. The measured light is in the UV, visible and NIR spectral region. Therefore many more elements can be analyzed compared to portable XRF. Elements hydrogen (H) to sodium (Na) may be measured by the Z, but cannot be measured by portable XRF. This includes critical elements like C, Li, Be, B, Na and others. The Z measures elements Mg, Si, Al at much lower detection limits, compared to portable XRF due to the optical nature of the technology.
