We offer a wide variety of products for the reliable water analysis of over 40 parameters. The colorimetric and titrimetric test kits VISOCOLOR ECO and VISOCOLOR HE are easy to use and can be evaluated without further accessories. The high precision NANOCOLOR test kits and VISOCOLOR Powder Pillows combined with our compact photometers and spectrophotometers offer a comprehensive analytical system with extensive possibilities for quality control.
Here we present useful information and practical tips on the use and application for our water analysis products.
In surface and ground waters, ammonium ions are an indication for the decomposition of animal or vegetable matter. High ammonia concentrations in surface waters can indicate contamination from waste water treatment plants, fertilizer runoff, or industrial effluents. Excess ammonia levels are toxic to aquatic life.
See how you can control your ammonium level with NANOCOLOR tube tests.
The AOX value indicates the content of organohalogen compounds, which are often found in industrial wastewater. These compounds are generally not biodegradable and are extremely harmful to humans and the environment.
Find out here how you can determine this important parameter with the NANOCOLOR tube test.
Besides the chemical oxygen demand (COD), the biochemical oxygen demand after 5 days (BOD5) is the most important cumulative effect parameter for assessment of the degree of contamination of a water body. Learn more about this important parameter and how it is performed.
Chlorine and its derivatives are the most important disinfectants for disinfection of swimming pools, water mains, and water reservoirs. Electroplaters use chlorine for the detoxification of cyanide-containing waste. Regular monitoring of chlorine level is essential as excessive chlorine not only impairs the smell and taste of water but also can be hazardous.
Besides the biological oxygen demand (BOD), the COD is the most important sum parameter for assessing the pollution of water. MACHEREY‑NAGEL test tubes provide results that are comparable to the DIN 38409 H-41. Many also fulfill the requirements of DIN ISO 15705.
Iron is one of the most common elements - essential for human life and indispensable in industry. Iron is also found in wastewater in dissolved form. It is not directly toxic to humans but is monitored for possible water use restrictions.
Learn how to determine this important parameter with our photometric test kits.
Nitrate ions are present at varying concentrations in ground and surface waters, as well as in municipal and industrial wastewaters. They are present almost exclusively in dissolved form in water samples.
See how you can control your nitrate level with NANOCOLOR tube tests.
Although nitrite occurs only in very low concentrations in surface waters, it is often strongly present in wastewater. It is an indicator for industrial wastewater or strong fecal pollution.
Learn here how you can easily and safely determine the nitrite content with the NANOCOLOR tube tests.
Phosphate is a common parameter in waste water analysis. It appears as ortho- or total phosphate and represents an indicator for industrial pollution or over-fertilization.
Learn how you can monitor your phosphate concentrations with NANOCOLOR tube tests.
The pH-value indicates whether a water or solution is acidic, alkaline or neutral. pH values play an important role in chemistry, engineering, and biological processes. Many chemical reactions, particularly chemical equilibrium reactions, are strongly influenced by the pH. In many such processes, exact determination and appropriate regulation and compliance with the specified pH is required.
Sulfate is a main component in rocks such as gypsum and alum and is therefore also found in natural waters. It is impossible to imagine industry without sulphuric acid and sulphates as basic chemicals. As higher sulphate levels are harmful to the environment and cause a bitter taste, monitoring them in drinking water and waste water is essential for the health of humans and nature.

Total nitrogen (TNb) is a cumulative parameter. TNb stands for total bound nitrogen. It is composed of organic nitrogen (e.g. urea, peptides or proteins) and inorganic or mineral nitrogen (ammonium/ammonia, nitrate and nitrite). Gaseous elemental nitrogen N2 which is contained in the water cannot be determined.
Zinc salts are used in electroplating for the galvanic zinc coating of steel in order to achieve an effective rust prevention. Also in cooling waters, zinc salts are applied as corrosion protection agents.
