FIELD: physics.SUBSTANCE: cuvette for analysed samples has an outer casing which forms a sample storage reservoir; a directional filling valve lying in the top end of the outer casing and forming the top edge of the sample storage reservoir, a filling valve for receiving a sample during filling and preventing sample leakage during ventilation after filling; and a film which covers the bottom edge of the outer casing, also forming the bottom edge of the sample storage reservoir, and a film for holding samples in the focal region of the analysing device. At least one X-ray optical unit can be placed on the excitation and/or detection path, requiring matching with the focal region.EFFECT: enabling formation of a cuvette with an accurately defined shape, which minimises contamination, reduces the probability of errors caused by operators, and which enables accurate positioning of the sample with respect to the X-ray analysis device.20 cl, 9 dwg |
