Methods for Environmental Water Assays (Fresh, Brackish, Salt Waters)

The FIAlab-2500/2600/2700 flow injection systems are ideally suited for the low/mid/high analyte ranges of fresh/waste water applications, as well as the ultra low detection limit requirements typical of many seawater samples.

Critical to seawater assays, FIAlab offers a long path flowcell with an optical path length of 50 cm - and an internal volume of only ~100 microliters.  This allows for measurements in the low microgram/liter range.  For ammonia consider the ultra sensitive fluorometric approach.  Please see  discussions on marine assay considerations.
