Online Calibration for Trace Sulfur Species
Kin-Tek Laboratories Inc.’s Span Pac™ 261 I dual-channel industrial permeation system produces suitable standards for calibrating total sulfur, which often requires a mix of compounds where the concentration of each compound is known. According to the company:
- One channel is operated at 40°C and is used for ppb COS plus 0.5ppm each of H2S, methyl and ethyl mercaptans.
- The second channel is typically operated at 60°C and is used for similar concentrations of dimethyl sulfide, dimethyl disulfide and/or thiophene.
- The Span Pac™ I is housed in a NEMA 4 cabinet and is available with Div 2 or Div 1 purge package for hazardous area service.
- Oven temperatures and permeation tubes are selected to suit the application.
