  • Page 9 (to avoid arcing). Intended use Endress+Hauser’s SS2100a products are high-speed, diode laser-based extractive analyzers designed for extremely reliable monitoring of very low (trace) to standard concentrations of specific components in various background gases.
  • Page 10 Due to the gas analyzer’s size and weight (configurations weigh approximately 130 kg [286 lbs]), Endress+Hauser recommends the use of a forkli�, pallet jack to li� and/or move the gas analyzer. If the gas analyzer is to be li�ed by hand, designate multiple individuals and distribute the weight among personnel to avoid injury.
  • Page 11 3 Product description Endress+Hauser gas analyzers are tunable diode laser (TDL) absorption spectrometers operating in the near-to-short wavelength infrared.

  • Page 12 With the SS2100a gas analyzers, sample gas flows continuously through the sample cell ensuring that the sample is always representative of the flow in the main pipe.
  • Page 13 SS2100a TDLAS gas analyzer Product description Description Laser Inlet Far mirror Optical head Detector Window Pressure sensor Temperature sensor Outlet Due to their inherent structure, the molecules in the sample gas each have characteristic natural frequencies (or resonances). When the output of the laser is tuned to one of those natural frequencies, the molecules with that particular resonance will absorb energy from the incident beam.
  • Page 14 3.3.1 Differential TDLAS Similar to TDLAS, this Endress+Hauser technology involves subtracting two spectrums from one another. A “dry” spectrum, a response from the sample when the analyte of interest has been completely removed, is subtracted from the “wet” spectrum, a response from the sample when the analyte is present. The remainder is a spectrum of the pure analyte.
  • Page 15 (ppm) or parts per billion (ppb) detection levels are possible (depending on target and background species) at real-time response rates (on the order of 1 second). All Endress+Hauser TDL gas analyzers employ similar design and hardware platforms.
