Can a Raman microscope be used for analysis of liquids?

Yes. A Raman microscope can be used to analyse liquids, as well as solids, slurries, gels, gases and powders.

Non-volatile liquids can be analysed by dropping a small volume onto a microscope slide, and focusing in the normal way.

Volatile (and non-volatile) liquids can be analysed in a liquid cuvette using a simple microscope adapter with a multipass reflecting mirror which boosts the signal intensity.  Alternatively, liquids can also be analysed directly in a glass vial or bottle – a confocal Raman microscope will ensure that there is minimum interference from the glass container, and allows a good quality spectrum of the liquid inside to be collected.
