Abstract
The response of a novel fiber-optic Raman probe to low levels of trich loroethylene (TCE) vapors is characterized. The detection limit of the current probe for TCE vapor is 34 mg/L, and the probe exhibits a full y reversible response. The probe uses an organic-polymer, low-density polyethylene to concentrate TCE vapors in the optical path of the fibe r-optic Raman spectrometer. The relative standard deviation for measur ement of 677 mg/L of TCE in the vapor is 0.3%.
