FIA-Universal Method Unit P/N
The Universal Method Unit P/N is destined for the determination of the basic parameters of water and soil analysis:
| Ammonium | 0,02 | - | 50 | mg/l | NH4-N | DIN EN ISO 11732 |
| Nitrite | 0,01 | - | 10 | mg/l | NO2-N | DIN EN ISO 13395 |
| Nitrate | 0,02 | - | 30 | mg/l | NO3-N | DIN EN ISO 13395 |
| Orthophosphate | 0,02 | - | 20 | mg/l | o-PO4-P | analog DIN 38405 T.11 |
Method change is fast and easy requiring only switching the valves on the method unit and exchanging the reagents without any hardware changes.

The fast startup of the FIAcompact together with the quick method change on the Universal Method Unit P/N make this system effective even for small sample series (from 5 samples).
The calibration of ammonium, nitrate and orthophosphate is made easy by the use of mixed standards.
