ATOM Instruments, USA

ATOM’s Excimer technology is the principal technology used in our analyzers for total sulfur measurement. The benefits of using this technology are numerous allowing analyzers to be designed for ease-of-use, reduced maintenance, and increased reliability.

Benefits:

Excimer Technology :

  • Higher Spectral Purity
  • Higher Relative Sensitivity
  • Highly Reduced Nitrogen Interference
  • Longer Life Relative to Other Sources (Operational and Calibration Cost Savings)

Analyzer Design :

  • Bottled O2not needed for Analysis
  • Bottled Carrier Gas not needed for Analysis (e.g.: Argon)
  • High Speed Analysis (60-100s per cycle for majority of applications)
  • Fast Response Time (99% of response in 1 cycle)
  • Standard Operation does not require installation in a shelter
  • Compact Footprint
  • Low Utility Consumption (4-6 weeks on standard 300 ft3compressed air bottle)
Principle of Operation :

The UV Fluorescence method is the most simple and practical low-level sulfur analytical technique. It has been widely used and proven over many years of use in industrial settings. This method involves the injection of a sample into a high-temperature oxidation furnace, converting all hydrocarbons into water (H2O) and carbon dioxide (CO2). Total sulfur contained in molecular-bound hydrocarbon species is oxidized at temperatures in excess of 1000°C into sulfur dioxide (SO2) by the reaction:

R-SH + R-NH + O2→ SO2+CO2+H2O

The furnace effluent containing these combustion byproducts is directed into a detection chamber where it is excited by high-energy, short-wavelength emission from the EUVF of Excimer UVF source. The UV photons from the excitation source, transfer energy into the SO2molecule and raise its energy level to create an excited singlet state. These excited molecules rapidly decay back to their lower energy ground state releasing the absorbed energy as a secondary emission known as fluorescence.


SO2+ hv → SO2*→ SO2+ hv’

Fluorescence emission is optically filtered to remove undesired wavelengths from excitation source and background scatter within the detector chamber. Detection of filtered fluorescence emission is accomplished using a Photomultiplier Tube and amplified by proprietary high sensitivity electronics.
