Abstract: A sample holder and method is disclosed. In one example, the sample holder is for spectrophotometric measurements of a sample using a transflection technique. The sample holder comprises a sample receiving chamber comprising a diffusive mirror, wherein a curvature of the diffusive mirror is adapted to a curvature of a surface of the sample and/or adapted to a curvature of a surface of a container comprising the sample. Further, a sample holder for spectrophotometric measurements of a sample using a transmission technique is disclosed. The sample holder comprises a hollow light guiding channel, wherein an inner wall of the hollow light guiding channel is covered by a smooth reflective coating and is configured to encase at least partially a tubular part of the sample or of a container containing the sample along a circumferential direction of the tubular part of the sample or of the container.

Abstract: A measurement chamber extension for a spectrophotometric characterization with a NIR-spectrophotometer of a Raman-spectrophotometer of a liquid in a polymer container, wherein a measurement chamber extension comprises: an adapter plate having an adapter opening; a container holder, and an optical element, selected from a mirror and a waveguide. The adapter is configured to cover in a light-tight manner the measurement chamber of the NIR-spectrophotometer or of the Raman-spectrophotometer. The container holder is configured to allow a close placement of the optical element adjacent to the polymer container containing the liquid providing a loss-free transmission or transflection of the measurement light beam from the optical element to a detector of the NIR-spectrophotometer or Raman-spectrophotometer.
