FTIR Heated Sample Lines

Measurement with FTIR (Fourier transform infrared spectroscopy) is very valuable in terms of speciation of pollutants, real-time results, and accurate determination of compliance with federal requirements. Sampling with heated Teflon ® PTFE tubes, however, can positively bias test results. This can lead to violations, fines, and un-planned shutdowns. Clean Air Engineering can provide heated sample lines that incorporate 304 stainless steel sample tubes, to prevent this positive bias. These lines are available with permanent or removable tubes, designed for continuous operation at 400° F. When used with a Teflon calibration tube, these sample lines provide a robust solution for highly accurate testing.

Permanent S.S. Liner w/ Optional Calibration line

FTIR Heated Sample Line (CEMS, Rata)
  • The removable Stainless Steel liner Part Number is 0723SSL. The removable S.S. liners outer deimension is 1/4" (0.250 O.D). The liner material is made from High-efficiency tubing because it can be bent and used in many applications. The removable line is also Acetone rinsed and capped to retain purity.
Removable 1/4" O.D. Stainless Steel Liner
FTIR Heated Sample Line Features:
  • Optioinal Removable 1/4" Stainless Steel liner
  • Rated for 400 º F continuous operation at -20 º F ambient temperature
  • Triple insulation maintains temperature of line with less power consumption. (Heavy Duty)
  • Lower resistance heaters requires less power to heat lines.
  • A backup type K thermocouple to prevent project delays in the case of primary thermocouple failure in the field.
  • Durable extruded poly-urethane jacket for protection of sample/calibration lines from abrasive failure in the field.
  • Inert teflon ® PTFE calibration lines will provide more accurate results by eliminating potential bias from other materials. Teflon is also more corrosion resistant than tygon, and can be washed with acetone without degradation.
