  • Push Button Validation
  • 4-20mA Output
  • RS-232/485 Communication
  • Direct Read LCD
  • Fast Response Time
  • General Purpose or Explosion Proof
  • Specific to H2S Only - No Interferences
Features and Benefits:

Save on lab analysis costs with unattended online analysis
Economical: Payout within days by reducing regenerator steam consumption to ensure spec sweet gas instead of over stripping. Reduce amine loss thru carry-over
Easy: Calibration is virtually never required. Permeation tubes can be used to generate samples to validate analyzer's proper operation.
Safe: Purge option for explosion proof ratings
Accurate: Grab samples for the lab deteriorate with time, H2S escapes during sampling. The Model 205 measures continuously, eliminating the need for costly and inaccurate grab sampling
Dependable: Sample Transfer Stripper™ for sampling radically reduces maintenance by ensuring a clean, dry sample to the analyzer

Description:

The ability to analytically quantify H2S (hydrogen sulfide) in non-volatile liquids, such as naphtha, water, crude oil (light, medium & heavy), and gasoline, are enhanced with the Sample Transfer Stripper S.T.S. (Patented Membrane Technology) and ASTM approved radiometric colorimetric technology methods offered by Analytical Systems International.

The principle of operation requires a continuous free flowing liquid sample into a heated oven where the Sample Transfer Stripper (S.T.S) unit separates the liquids from the H2S gas sample. An H2S free air or nitrogen carrier then sweeps the H2S gas sample to the H2S analyzer for quantitative analysis in ppb, ppm, and up to saturation levels. A liquid validation by PermTube™ is optional. The detection technology is based on chemically specific density changes. The sensing tape utilized in this analyzer is the only detection method that is absolutely specific to H2S. Optical illumination & detection are integrated for maximum resolution accuracy. The electrochemical detection method is also available. Economic payout is increased because of this automated continuous process or laboratory analyzer.
