| 20100173419 | METHOD AND DEVICE FOR DETERMINING THE PHOSPHORUS CONTENT OF AN AQUEOUS SAMPLE - Method for determining the phosphorus content of an aqueous sample, in particular drainage-water sample, wherein the sample is subjected to thermal-oxidative decomposition and the orthophosphate content of the decomposed sample is determined photometrically in an aqueous analysis solution, such that the thermal decomposition is carried out in a single step by catalyzer-free burning of the sample as batch-decomposition in a combustion oven, the resulting combustion gas is transferred out of the combustion oven in a carrier-gas stream and the combustion/carrier gas stream is cooled to obtain the aqueous analysis solution as a condensate therefrom. | 07-08-2010 |
| 20090186417 | Method for Determining the Oxygen Requirement of an Aqueous Solution for a Purification Process - Method of determining the oxygen demand, TOD or COD, of an aqueous solution, in particular of waste water, for a clarification process, wherein a sample of the aqueous solution is decomposed by combustion, such that the combustion is carried out without the presence of a catalyst, at a temperature above 1150° C., in particular at 1200° C. | 07-23-2009 |
