Claim One:
1. A method for inspecting a volume and a composition of at least first fluid sample ( 11 ), said method comprising: (a) providing a pipette ( 1 ), in which at least one interface is formed between the at least one sample ( 11 ) and at least a first fluid ( 15 ) which is adjacent to the first sample ( 11 ), said interface being optically perceptible outside the pipette ( 1 ) in the first case as an about horizontal interface line ( 11 a ) between the at least one sample ( 11 ) and the at least first fluid ( 15 ); (b) arranging at least one marking ( 33 ) of a camera ( 30 ) in an image field of the camera ( 30 ), such that the at least one marking ( 33 ) and at least a first section ( 1 c , 1 d ) of the at least one pipette ( 1 ) are reproduced on a recorded image ( 38 ), with the at least one pipette ( 1 ) being arranged between a light source ( 20 , 20 a - 20 e ) and the camera ( 30 ) such that at least one spectrum ( 13 ) of light beams ( 22 - 24 ) of the light source ( 20 , 20 a - 20 e ) that have passed through the first sample ( 11 ) can be recorded by the camera ( 30 ); (c) evaluating whether the at least one marking ( 33 ) in the recorded image ( 38 ) matches a position of at least one interface line ( 11 a ) in the at least first section ( 1 c , 1 d ); (d) comparing a first recorded spectrum ( 13 ) with at least one reference spectrum; and (e) determining whether the composition of the at least one first sample ( 11 ) in accordance with the at least one recorded spectrum ( 13 ) corresponds to that of the at least one reference spectrum.
