Laser-referenced interferometers

The potential to interface a gas chromatograph to a rapidscanning infrared interferometer was recognized shortly after the interferometers became available. The earliest studies used low resolution interferometers.17,19 jhis vwrk was quickly expanded to laser-referenced interferometers capable of high-resolution studies. 19,20 ji g of this work was to collect the infrared...

The infrared spectra were produced using a Nicolet 170SX Fourier Transform Infrared spectrometer. This infrared spectrometer is equij ied with a laser-referenced Michelson interferometer with... [Pg.1079]

The Connes advantage claimed for interferometers was that laser referencing would yield much greater wavelength accuracy and reproducibility. The latter was crucial for both signal averaging and spectral subtraction but, as the Perkin-Elmer company had shown, this could almost be matched by dispersives. [Pg.1258]
