Laboratory Raman and AutoSampler Accessories

• Most spectroscopic analysis requires modeling of grab sample spectra and ASTM laboratory measurements
• We have simplified this time consuming process
  • Auto sampling accessories for acquiring Raman spectra for
    • Liquids
    • Liquefied petroleum gases

Liquids – auto sampling

• Liquid auto sampler holds up to 39 stream samples at one time
  • Plus 3 sample vials of toluene for cleaning and calibration
• Typical sampling time is 3 minutes per sample
  • Ideal for running emergency unit samples
• Auto sampler runs unattended
  • Allows for overnight operation
  • Frees up personnel and laboratory equipment – reduces overhead
  • Allows modeling of potential process streams prior to committing to online analysis
• Samples are housed in disposable 40 ml septum-lid glass vials
  • Use for octane, RVP, distillation, etc.
• Samples are pressurized to ~15 psi
  • Reduces light-end loss during measurement

Liquefied petroleum gases – auto sampling 

• Liquefied petroleum gases (LPG) auto sampler can run high pressure LPG
  • Simplified modeling of LPG streams
• Uses standard high pressure sample bomb cylinders with quick connects
  • Sample-bomb cylinders from 250 cc to 500 cc
  • Cylinder pressure up to 300 psi (2,100 kPa)
• Requires one sample bomb for calibration
  • Accepts up to 5 sample bombs
• Accepts up to 5 sample bombs
• A single Raman installation can replace multiple online gas chromatographs
