This application note describes how to use a LINKAM THMS600 hot-stage as a sample holder connected to a Cary 5 UV-Vis-NIR spectrophotometer to obtain temperature-dependent UV-Vis absorption spectra of polymer thin films.
The document details an experimental setup where a LINKAM THMS600 hot-stage, originally designed for optical microscopy, is adapted to serve as a sample compartment within an Agilent Cary 5 UV-Vis-NIR spectro-photometer. This configuration allows for the measurement of solution and solid-state spectra under carefully controlled temperature and atmospheric conditions.
The LINKAM THMS600 can be conveniently used in the temperature range -100-300 °C using the standard Linkam temperature control unit TMS91.
All standard glass windows must be replaced by quartz windows with a diameter of 22 mm and a thickness of 0.5 mm.
Photometric noise remains excellent at 0.0007 A with the hot-stage installed.
