SYSTEA manufactures a wide range of on-line analyzers, named Micromac C, using well established and standard colorimetric methods applied on more than 50 applications of chemical compounds monitoring in water.
MICROMAC C is a microprocessor controlled colorimetric on-line analyzer specifically designed for on-line industrial and environmental control unattended monitoring.
Easychem online is our state of the art line of products based on Discrete technology with direct reading technique, allowing the online monitoring of several chemical parameters in the same unit, acute toxicity and coliforms online detection too.
Two products are available for portable analysis of chemical parameters in water:
Both products are available either in mono or sequential mutiparametric configuration, providing the highest level of analytical automation and compactness. μMAC-1000 andμMAC-Smart are the only available high sensitivity multiparametric portable analyzers using colorimetric approved methods.
These analyzers can measure many type of water samples on a wide range of applications, including sea water.
SYSTEA is one of the few companies in the world offering a line of in-situ probes to measure nutrients and other chemical compounds in surface and sea water.
The available products are the following:
Our probes can analyze up to 4 nutrients in the same device, using official colorimetric methods but also fluorimetric detection techniques.
Our laboratory analyzers product range covers most of the needs for automatic and reliable routine analysis of inorganic compounds in water and water extracts, like Ammonia, Nitrate, Nitrite, Orthophosphate, Silicates, Total Nitrogen, Total Phosphorus, Total Dissolved Iron, Chromium, Aluminium, Manganese, Copper, Nickel, Zinc, Alkalinity, Hardness, Sulphate, Residual Chlorine, Chloride, Calcium, Magnesium, Cyanide, Phenols, Boron, Urea, TOC.
MICROMAC ECO is a microprocessor controlled on-line analyzer, specifically designed for automatic monitoring at the outlet of WWTPs.
Feature and benefits
For waste water or other dirty samples application a self-cleaning filtration unit can be installed close to the analyzer. Thanks to the integrated PLC, the filtration unit runs periodically a self cleaning cycle, using compressed air generated externally or even internally (as option). One filtration unit can be used to supply a clean water sample up to 10 analyzers.
Three versions of COD on-line analyzers are available:
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 C is a colorimetric microprocessor controlled On Line analyzer specifically designed for automatic monitoring on several type of waters matrix.
Batch Continuous Flow Analysis (BCFA) hydraulics was recently applied to measure specific chemical parameters which needs a particular sample conditioning:
