General Information:
In order to support our clients, we have created dedicated analysis packages for the characterization of water quality. The 1st set of analyses includes the following analyses: pH, conductivity, turbidity, chlorides, hardness, iron, magane, being generally useful for the characterization of the physico-chemical parameters of the waters dedicated to domestic purposes (washing, sanitizing, various household uses, etc.)
The referential after which the analysis/ Principle of the method is executed:
The analysis for the determination of the turbidity to the drinking water is performed within its own laboratory according to the national and international standard in force according to the table below.
SET 1 - PHYSICO-CHEMICAL ANALYSIS | ||||
No. crt. | Name of the test | Referential | Min quantity of sample( ml ) | Execution time( working days ) |
| 1 | Determination of pH | SR EN ISO 10523:2012 | 100 | 2 |
| 2 | Determination of conductivity | SR EN 27888:1997 | 100 | 2 |
| 3 | Determination of turbidity | SR EN ISO 7027/2001 | 100 | 2 |
| 4 | Determination of chlorides | SR ISO 9297/2001 | 250 | 2 |
| 5 | Determination of hardness (amount of calcium and magnesium) | SR ISO 6059:2008 | 150 | 2 |
| 6 | Determination of iron | SR 13315:1996+C91:2008 | 100 | 2 |
| 7 | Determination of manganese | SR 8662-2:1996 | 100 | 2 |
Causes of sample rejection – quantity of inappropriate sample, samples collected in inappropriate containers, samples not properly labeled, etc.
Harvesting container – clean container.
Quantity of sample necessary to perform the analysis - minimum 950ml.
Necessary processing after harvesting – not required.
Sample stability – freshly harvested water is stable for 2 days at 2-8°C or 6 hours at ambient temperature.
