Remote Determination

We have examined the feasibility of the remote determination of water in a sodium nitrate matrix by fiber-optic Raman spectroscopy with multichannel detection. The direct determination based on the Raman line due to OH bending is shown to be possible but relatively insensitive. A determination based on the ratio of signals due to dissolved and solid nitrate is shown to provide a water detection limit of less than 1% for a measurement time of one minute.
