• Description:
  An investigation was performed to determine, in the simplest of situations, whether or not the infrared methods of analysis were accurate. The causes of the inaccuracies exhibited in the determination of trichloroethylene (79016) (TCE) in the presence of Freon-113 (76131) in the air were also examined. A comparison of measurements using the Fourier transform infrared spectrophotometer (FTIR) and the Miniature Infrared Analyzer (MIRAN) were obtained using a gas chromatography. The investigation involved the effects of instrument resolution, relative humidity and sample storage stability. No effect on the performance of the FTIR over the range examined was noted to be the result of changes in the relative humidity. The linear range of the FTIR was more than adequate for the concentrations encountered. However, when the concentration of certain analytes approached the 50 to 150 parts per million range, readjustment of the gas cell to a shorter path length was recommended for the MIRAN. Interference from Freon-113 caused the TCE values to be higher when the MIRAN was operated in the single wavelength mode. [Description provided by NIOSH]
