Abstract
According to an example aspect of the present invention, there is provided a sample container for use inside an optically integrating cavity, comprising an enclosing member comprised of fluorocarbon plastic, the enclosing member having diffuse transmittance of at least 80% and the sample container being adapted to contain a solid or liquid sample.
Claims15
A sample container for use such that the sample container is in its entirety inside an optically integrating cavity, comprising:
- an enclosing member comprised of fluorocarbon plastic;
- the enclosing member having a diffuse transmittance of at least 80%;
- the enclosing member comprising a shield part which is a baffle or a scattering element having diffuse transmittance of less than 20%, and
- the sample container being adapted to contain a solid or liquid sample, the sample container not being built or installed as part of a wall of the integrating cavity, and wherein the sample container is so adapted as to enable, during a measurement, placement of the shield part between the solid or liquid sample and a light input port of the integrating cavity, when the sample container is inside the integrating cavity.
1 more element
A method, comprising:
- placing a solid or liquid sample in a sample container, the sample container comprising an enclosing member comprised of fluorocarbon plastic, the enclosing member having a diffuse transmittance of at least 80%, the enclosing member comprising a shield part which is a baffle or a scattering element having diffuse transmittance of less than 20%, and
- performing a measurement with the sample, with the sample and the sample container placed in their entirety inside an optically integrating cavity, the sample container not being built or installed as part of a wall of the integrating cavity, wherein during the measurement the shield part is oriented between the solid or liquid sample and a light input port of the integrating cavity, the sample container not being built or installed as part of a wall of the integrating cavity.
