Tunable temperature and measuring angle holder for film and powder samples

Researchers from the CSIC and the Catalan Institute of Nanoscience and Nanotechnology (ICN2-BIST) have developed and patented a sample holder for measuring films or powder samples in a fluorimeter or a UV-Vis-NIR spectrometer in transmission or reflection modes. The holder allows controlled temperature conditions, and an adaptable measuring angle. The device is customizable to adapt to the diverse commercial instruments.

Graphic of the new holder for samples.Current UV-Vis spectrophotometers, fluorimeters and spectroscopic instruments are becoming more compact equipment and user-friendly. The disadvantage of this is that instruments are becoming more and more specific for some measurements and less flexible and modular. This is particularly true for the sample chamber and holders.

To compensate this, the supplier companies offer accessories to allow some specific and less conventional types of measurements. Nevertheless, these accessories often lack some characteristics, which might difficult the task as they are generally useful for one specific equipment, but not for another of the same brand nor for the same type of equipment of different brands.

The novel holder allows measuring films (both transparent and opaque films) or powder samples in a fluorimeter or UV-Vis-NIR spectrometer in both modes (transmission or reflection).

The holder allows conditions to assure a homogeneous and stable heating of the sample, from room temperature up to 200ºC, and an adaptable measuring angle for tuning the light incidence and the light detection angle. It is suitable for UV-Vis-NIR standard and transient absorption spectroscopies, Raman measurements and steady-state or time-resolved emission spectroscopies (fluorimeter). Customizable to fit in many spectroscopy instruments, enables an easy change of samples inside the holder and a quick setup of the holder in the equipment.
