With our TP/TN-Analyzer the total phosphorus or total nitrogen content of homogenised water samples can be measured without time-consuming sample preparation. The analysis method is based on DIN EN ISO. Specified measurement ranges: Total nitrogen: 0.05 … 20 mg/l TN Total phosphorus: 0.1 … 20 mg/l TP In our FIAcompact there is an integrated UV and thermal digestion unit. Phosphorus or nitrogen containing compounds react to ortho-phosphate or nitrate. Measurement of total phosphorus down to 10 … 500 µg/l P in samples of surface water is possible with our method including a solid-phase extraction.
