Abstract

This note describes a simple, convenient sample holder for laser Raman spectroscopy of liquids and powders at any temperature between −196° and +200°C. It was designed for the Spex Ramalog system, which uses 90° viewing. With this system a liquid or powdered sample is contained in a thin-walled melting point tube which is oriented crosswise to the slit, i.e., parallel to the plane of the slit jaws and perpendicular to the long axis of the slit. The laser beam impinges on the sample vertically, and the scattered radiation is viewed horizontally.
