Abstract: A nephelometric turbidimeter with a cylindrical turbidimeter vial. The cylindrical turbidimeter vial includes a transparent vial body and a circular optical shielding configured to optically block an inside from an outside of the turbidimeter vial. The vial body comprises a transparent and flat bottom inlet window, and a transparent vial cylinder body. The vial cylinder body comprises a circular outlet window. The optical shielding is arranged axially above the outlet window of the vial cylinder body, over a part of an axial length of the vial cylinder body, and axially adjacent to a non-shielded part of the vial cylinder body which serves as the outlet window.

Abstract: A nephelometric turbidimeter for measuring a turbidity of a liquid sample in a sample cuvette. The nephelometric turbidimeter includes a measurement light source configured to emit an axial parallel light beam directed to the sample cuvette, a scattering light detector arranged to receive a scattered light from the sample cuvette, and a diffuser comprising a diffuser body and a diffuser actuator. The diffuser actuator is configured to move the diffuser body between a parking position in which the diffuser body does not interfere with the axial parallel light beam and a test position where the diffuser body is arranged between the measurement light source and the sample cuvette so that the diffuser body interferes with the axial parallel light beam and generates a diffuse test light entering the sample cuvette.

Abstract: A method for determining a phosphate concentration in a water sample includes providing the water sample, adding a first acid to the water sample to obtain a second water sample in which a concentration of the first acid is at least 0.5 wt.-%, performing a first photometric measurement of the second water sample, adding a coloring component to the second water sample to obtain a third water sample, performing a second photometric measurement of the third water sample, and calculating the phosphate concentration from a difference between the first photometric measurement and the second photometric measurement.

Abstract: A nephelometric turbidimeter for measuring a turbidity of a liquid sample in a transparent sample cuvette. The nephelometric turbidimeter includes a cuvette chamber housing with a cuvette chamber having the transparent sample cuvette arranged therein, and a drying apparatus. The drying apparatus includes a cuvette chamber inlet opening which vents the cuvette chamber, a cuvette chamber outlet opening which de-vents the cuvette chamber, an air circulator which circulates air from the cuvette chamber outlet opening to the cuvette chamber inlet opening, and a drying body. The drying body is provided as a container of a hygroscopic agent defined by a drying substance which is arranged in a drying path between the cuvette chamber outlet opening and the cuvette chamber inlet opening so that air flows through the drying body.

Abstract: A method for detecting a contamination of a cuvette of a turbidimeter. The turbidimeter includes a light source which emits a light beam directed to a cuvette, a scattering light detector, and a diffuser with a body and an actuator. The actuator moves the body between a parking position and a test position where the body is between the measurement light source and the cuvette, thereby interferes with the light beam, and generates a diffuse test light entering the cuvette. The method includes activating the actuator to move the body from the parking position into the test position, activating the light source, measuring a test light intensity received by the scattering light detector, comparing the test light intensity measured with a reference light intensity, and generating a contamination signal if a difference between a reference light intensity and the test light intensity measured exceeds a first threshold value.
