Abstract
Fourier transform Raman spectroscopy has been carried out remote from the instrumentation using fibre‐optic probes. The quality of the data is good; the measured signal‐to‐noise ratios from spectra obtained using a conventional sampling arrangement are better only by a factor of ca. 5. The choice of fibre‐optic material and grade is crucial to the success of this work. Two different fibres have been tested and compared. Technical improvements are discussed.
