General description

LAMPS (Laser Assisted Microwave Plasma Spectroscopy) by Ocean Insights represents a major leap forward in LIBS (Laser Induced Breakdown Spectroscopy) technology. The LIB technology provides quantitative analyses of most samples by ablating a very small portion of a sample and examining the wavelengths of the resulting plasma. LAMPS enhance the plasma increases sensitivity for most potential analytes. Also enhanced are emission line stability and reproducibility, leading to better quantification results. Analyses of a variety of diverse analytes that require greater sensitivity over traditional LIBS and less ablative sample imprint are now made possible with LAMPS.

The system

The key to both LIBS and LAMPS elemental measurements is the ability to acquire high resolution spectra of a transient event, over a broad wavelength range. This is accomplished by coupling 7 HR2000+ spectrometers into one system of, typically 7 channels. Each spectrometer covers the spectrum (~100-140 nm typically) The spectral region covered can start as low as 200 nm for Channel 1 and ending with 980 nm for Channel 7 for full spectrum coverage. However, systems may be configured to start above 200 nm and with 1 or with only a few channels for element-specific applications. Such configurations can be particularly cost effective when compared with any other elemental analysis system.

Possible analytes

Analytes that can be analyzed with LAMPS:

  • Metals
  • Inorganic solids
  • Slurries/liquids (paints, petroleum, food, etc.)
  • Organic solids (tars, plastics)
  • Natural materials (soils, refuse, etc.)
  • Powders

Avoid live tissues and highly combustible materials.
