Instrument - Bomem FTIR
What is being measured:
Data recording software:
Data analysis software:
Raw data time resolution:
Usually after each period of photolysis of chamber contents (typically 5 min)
Analysis data averaging:
Tens of ppbv for many small IR-active molecules
Sensitivity to temperature (and correction method, if applicable):
Sensitivity to relative humidity (and correction method, if applicable):
Chamber is run dry.
Sample preparation method:
Sample residence time (chamber to instrument) (seconds):
Length of tubing (cm):
Instrument flow rate:
Tubing inner diameter:
Chemical identification method:
Infrared absorption, quantification via comparison with standard spectra (usually recorded in-house).
Data analysis method:
Spectral analysis using commercial 'spectral stripping' routines
Comparison with standard spectra, usually recorded in-house.
Calibration drift estimate:
Uncertainty estimation method:
Estimated from observations made during 'spectral stripping' analysis.
