Cold technique for nitrogen quantification in liquid
This new technique is rapid (about 10 minutes), non corrosive (without acid or heating) and economic
(limited consumables) and uses an oxidation system through " hard " UV
coverage to convert nitrogenous form in to nitrate.
Prediction of a liquid sample biodegradability
After the UV oxidation of the solution in the OXI 50 module, nitrate can be read
by usual chemical dosage or within a few seconds by direct reading thanks to
SECOMAM PASTEL UV or ANTHELIE spectrophotometers.
According to the PH conditions, the OXI 50 can measure total or ammoniac
This technique provides results that are completely consistent with the
reference method (CV>97%) with a 1mg/L sensitivity. This instrument, compact,
easy to use and without any danger, replaces KJELDAHL systems in environmental,
chemical or agrifood laboratory
Facing a potentially polluting sample or effluent, a laboratory can only use DB05 to standardize its
With OXI 50, SECOMAM offers an alternating technique of the biodegradability
estimation : the UV photo degradability.
This photo degradability checks the organic molecule resistance towards
degradation. Within one or two hours of UV raying in the OXI 50, the system
calculates the organic substance level decrease in the sample, this rate is
directly proportional to the solution biodegradability.
This correlation, tested in many fields is about 90% and any inaccurate result
This new technique, rapid and easy to set, is used in both environmental
laboratory and in new molecules resistance screening in research or industrial
