Abstract:

The body of the miniature long path gas cell arrived from the machine shop. The body has been supported on the optical bench, along with transfer optics and the FT-IR spectrometer. The end-cap mirrors are all that are needed to complete the Phase I system. Diamond machining of the end-cap mirrors has been completed, and the parts were sent to the vendor for coating with protected silver. Measurements were made for trichloroethylene TCE with a gas analyzer equipped with a 20 meter, 1.6 liter volume cell that used gold coated mirrors of less than optimal sufface quality. 50 ppb TCE was easily detected 20 ppb TCE did not greatly emerge above the instrumental baseline noise level. The results were promising when analyzed with regard to that expected for the novel cell being constructed.
