Abstract
Provided are an attachment for liquid sample measurement which is capable of effectively reducing a consumption amount of a liquid sample, a refractive index measuring device and a refractive index measuring method. An attachment (100) is disposed on a V-block prism (1) formed on a V-shaped groove (11) for keeping a sample so as to enter the groove (11). A body (110) of the attachment (100) forms an enclosing space (107) for enclosing the liquid sample between the body and a surface of the groove (11) formed on the V-block prism (1), and makes the liquid sample enclosed in the enclosing space (107) contact directly with the surface of the groove (11).
Claims7
An attachment for liquid sample measurement, which is disposed on a V-block prism with a groove which is a V-shaped groove for keeping a liquid sample formed thereon so as to enter the groove, and is used when a refractive index of the liquid sample is measured by a V-block refractive index measuring device,
- the attachment for liquid sample measurement comprising:
- a body, which forms an enclosing space for enclosing the liquid sample between the body and a surface of the groove formed on the V-block prism, and makes the liquid sample enclosed in the enclosing space contact directly with the surface of the groove.
A refractive index measuring method, comprising:
- an attachment disposing step, in which an attachment for liquid sample measurement is disposed on a V-block prism on which a groove which is a V-shaped groove for keeping a liquid sample so as to enter the groove, thereby forming an enclosing space for enclosing the liquid sample between a surface of the groove formed on the V-block prism and the attachment for liquid sample measurement;
- and
- a measuring step, in which a measuring beam is irradiated, via the V-block prism, to the liquid sample enclosed in the enclosing space so as to contact directly with the surface of the groove, thereby detecting the measuring beam transmitted through the liquid sample and measuring a refractive index of the liquid sample.
