摘要： The invention is directed to a process water analyzer (10) for automatically analyzing a parameter of a water sample, comprising
a process liquid reservoir tank (70,72) with a process liquid (70',72'), whereas the process liquid reservoir volume (V70,V72) in the reservoir tank (70,72) defines a reservoir liquid level (170,172) at a reservoir liquid level height (h70, h72),
a dosage chamber (30) fluidically connected to the process liquid reservoir tank (70,72) and being positioned fluidically downstream of the process liquid reservoir tank (70,72), and
a positive displacement dosage pump (20) fluidically connected to the top of the dosage chamber (30) for sucking in the process liquid (70', 72') into the dosage chamber (30),
whereas an air cushion (27) is always provided vertically between the dosage pump (20) and a dosage chamber liquid level (I) in the dosage chamber (30), so that a liquid column (Ic70, Ic72) with an effective vertical liquid column length (c70,c72) is given between the reservoir liquid level (170,172) and the dosage chamber liquid level (I),
whereas the dosage pump (20) directly sucks a pressure-adapted gas volume (Vgas) of the air cushion (27) having an air cushion pressure (P) so that a set process liquid volume (Vliquid) is pumped into the dosage chamber (30), and
whereas a process liquid dosage control unit (200) is provided, the process liquid dosage control unit (200) providing the value of the pressure-adapted pumped gas volume (Vgas) dependent on the air cushion pressure (P) effected by the effective vertical liquid column length (c70,c72).

摘要： A method for determining a phosphate concentration in a water sample. The method includes providing the water sample, determining a first phosphate concentration of the water sample via a molybdenum yellow method or via a variant of the molybdenum yellow method at a first temperature, and, if the first phosphate concentration is falls within a specified range, determining a corrected phosphate concentration of the water sample via the molybdenum yellow method or via the variant of the molybdenum yellow method at a second temperature.

摘要： The invention refers to a photometric process measurement arrangement (10) with a photometric immersion probe (20). The photometric immersion probe (20) comprises a photometer flashlight source (61) for providing photometric light impulses, a photometric detector arrangement (70) comprising at least two separate wavelength-selective detection elements (71, 72, 73), and a photometer control (80) controlling the photometer flashlight source (61) and the detector arrangement (70). The photometer control (80) comprises several impulse signal integrators (81', 82', 83') for integrating the electric impulses generated by the detection elements (71, 72, 73), several A/D-converters (81, 82, 83) for converting the voltages of the impulse signal integrators (81', 82', 83') when high-precision-converting trigger ports (H) of the A/D-converters (81, 82, 83) are triggered, and
a measuring cycle control (90) with an integration target memory (94) memorizing an integration target voltage value (Ut). The photometer control (80) is provided with a high-precision-request port (93) for synchronously triggering the high-precision-converting trigger ports (H) of all A/D-converters (81, 82, 83) after the voltage of the first of all impulse signal integrators (81', 82', 83') has exceeded the memorized integration target voltage value (Ut).
