The analyzer is easy to be installed and it is designed for easy operations, the analyzer can be used at site after a quick training. It is delivered from factory fully tested and ready to use reagent kits are available for all standard measurements. Results are stored inside the analyzer memory and can be downloaded through the USB port .Analyzer start up and operations have never been easier! Just turn on and insert the reagents: a simple software will guide the operator through all necessary steps.
Automated calibration
The analyzer calibration is fully automated; just use the calibration solution as specified in the manual and run. The new calibration factor is checked and accepted if verified to be comprised within acceptance limits.
Multiple parameters
The analyzer can be delivered ready for multiple measurements (MP versions) on the same sample; several multiparametric configurations are available as standard (see here below).
Multiple measurements
The analyzer offers the option for continuous operational mode; the operator can perform sequential measurements several times on the same sample or just leave the analyzer running while the water sample flows.
Off-scale reanalysis
The analyzer identifies off scale samples and reanalyze the water sample after automated dilution.

NPA Pro
Nutrients probe analyzer
|
NPA Pro is submergible multiparametric in-situ probe for sequential automatic analysis of up to four nutrients or other chemical parameters in surface and sea water, based on μLFR* technology. The standard wet chemistries for nutrients analysis used in NPA Pro are the ones recommended by international standard:
* Patented New innovative chemistries are also available to make easier the management of the on site operations:

 |
The NPA Pro has been designed to be best integrated in coastal buoys. The two cylinders can be easily placed on the buoy’s body holes and then simply anchored with chains or hooks or snaphooks.It is made of two different PVC cylinders:
A single hydraulic connector with 10 tubing is used to connect the second cylinder to the first one. This multi-connector is provided with a valve to open it during functioning and to close it during transportation, to avoid reagent spillage. |
Advanteges and benefits
- Two cylinders are more convenient/easy to deploy: the electronic compartment is never removed;
- The NPA Pro doesn't unbalances the buoy: the single body, if placed externally, can tilt the whole system that needs redistribution of buoyancy;
- If needed, the Cd column, may be placed just above the electronic compartment;
- The reagent compartment may be changed as a whole; its allowance is around 17 litres;
- Long lasting reagents quantity, expected reagent changeover every 45/60 days.

Micromac COD
On-line analyzers for COD monitoring
in water and wastewater
Three versions of COD on-line analyzers are available:
- dichromate method
- permanganate index method
- UV direct reading method.
The dichromate method follows the international standard where in the sample, after filtration, Potassium Dichromate, Mercury (II) sulfate and Sulfuric acid with a proper catalyst are added; Mercury (II) sulfate concentration is adjusted to mask the expected Chloride amount.
The sample is then heated at 170° for 20 minutes or at 150° up to 2 hours (digestion time and digestion temperature can be adjusted depending on the matrix to digest completely all the substances that give a contribute to COD). After digestion the sample is cooled and the absorbance measured at 592 nm is proportional to a COD concentration.
The permanganate index is defined as the quantity of oxygen, expressed as mg/l, equivalent to the consumed permanganate when a water sample is treated with as solution of potassium permanganate in acid environment and at a temperature of 100°C for 10 minutes. The sample is mixed with diluted sulphuric acid, it is then heated at about 100°C, when the first addition of KMnO4 is performed: this first addition may be followed by others, depending on the measuring range. The digestion time in the standard configuration is set to 10 minutes but it can be selected depending on the matrix.
After digestion the sample is cooled and the decrease of the absorbance measured at 525 nm corresponds to the permanganate consumed by the organic substance.
The UV direct reading method is a more simple method where the COD is correlated to the direct light absorption of the water sample measured at 254 nm.

Micromac Total N&P
On line analyzer for nitrogen and phosphorus
monitoring in surface and waste water
Micromac C TN&TP is designed to analyze Total Nitrogen and Total Phosphorus in the same device; UV digestion is applied for Total N, UV and high temperature digestion for Total P.
The measurement is performed in a combined mode, ensuring one hour of measurement for both parameters; 4-20 mA data output is provided at the same time.
Measurement method
The sample after proper filtration is pumped inside the LFA reactor, where after injection of H2SO4 is trapped inside the high temperature heating bath for inorganic P hydrolysis. During the hydrolysis time, the analyzer runs a complete TN test on the same sample, by adding the oxidation reagents and passing through a UV digestion step, to convert Nitrogen into Nitrate by UV radiation in persulfate alkaline medium. The nitrates formed are then reduced to nitrites by hydrazinein alkaline solution, where copper is used as catalyst; the nitrites react with sulphanilamide and naphtylethylendiamine in acid solution, to form a pink colored compound measurable at 550 nm. The reactor is washed and then the analyzer opens the heating bath and adds in the digested sample a proper oxidant to convert all the organic forms of phosphorus into orthophoshate, by the double action of potassium persulphate and UV radiation in acid environment. The orthophosphate formed reacts with molybdate to form phosphomolybdate, which is finally reduced to bluemolybdenum by ascorbic acid. The coloured complex is read at 660 or 880 nm.
Technical specification

| Measuring principle | Colorimetric, UV digestion + UV reduction to NO3 | Colorimetric, acidic hydrolosis and UV digestion |
