| 摘要 |
The invention relates to a method for expanding the measurement range when determining the concentration of a dissolved material (2). The solution of the dissolved material (2) is metered into a measurement cell (11) to a defined quantity of a provided reagent (1) by means of a micro-metering device (3, 4, 5) until the color produced by the reaction of the dissolved material with the reagent reaches a previously determined extinction value X in a photometrically detected manner. The quantity of the required dissolved material (2) on the micro metering device (3, 4, 5) is then detected, and the concentration is calculated based thereon, wherein the volume of (2) is much smaller than the volume of (1). |
