Abstract

A sample receptacle apparatus (100) for arranging a fluid sample (1) in a beam path (2) of measuring radiation (3) in a gas-tight measuring apparatus (200), comprises a sample cell (10) having plane, plate-shaped cell windows (11) with a spacing therebetween, wherein the sample cell (10) is configured for accommodating the sample (1) in the spacing between the cell windows (11), and a cell holder device (20) having a cell support body (21), a first coupling section (22) and a second coupling section (23), wherein the cell support body (21) is configured for accommodating the sample cell (10) and for setting a temperature of the sample cell (10), the first and second coupling sections (22), (23) are configured for a gas-tight coupling of the cell holder device (20) with a closed container device (240) of the measuring apparatus (200), and the cell holder device (20) provides a beam passage (4) along a longitudinal direction z through the first coupling section (22), the cell support body (21) with the sample cell (10), and the second coupling section (23), wherein the sample cell (10) is arranged in the beam passage (4) such that a normal of at least one of the cell windows (11) deviates from the longitudinal direction (z) of the beam passage (4). Furthermore, a measuring apparatus for a spectroscopic investigation of a sample, including the sample receptacle apparatus (100) and a spectroscopic measuring method are described.
