Ambient air quality Ambient air quality – critical for our health and the environment. For several decades, the emission of aerosols and their precursor gases has continuously increased due to growing populations, industrialisation and human activities. It has been known for some time that elevated concentrations of certain species in...Read More

Combustion IC The new combustion IC from Metrohm offers a novel and robust method ideal for fluorine analysis of Cu concentrates. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to...Read More

OMNIS is the ultimate platform for wet chemical analysis. With OMNIS, you can perform up to 4 fully automated titrations at the same time on the same system! Determine, for example, pH & alkalinity, total hardness, chloride, and fluoride simultaneously in up to 175 samples! Scale up any way you...Read More

Metrohm: pH and Conductivity of Soil and soil extracts Chromatogram of 10 ppb cyanide and sulphide in water. In many soil analysis laboratories pH and Conductivity of soil or soil extracts is a vital but tedious task. CaCl2 needs to be added often as well. The whole process can be...Read More

In the membrane electrolysis production of chlorine the purity of the brine is very important. Chlorine is produced from salt with three different technologies. The membrane technology now accounts for 51.2% followed by the mercury process (31.8%) and the diaphragm process (14%). The shift towards membrane technology is in line...Read More

Cyanide and sulphide via IC Chromatogram of 10 ppb cyanide and sulphide in water. The trace determination of cyanide and sulphide require an alkaline eluent and amperometric detection. Metrohm presents an application note for the determination of cyanide and sulphide via ion chromatography using amperometric detection. This Application Note describes...Read More

The Metrohm Dis-Cover in use for peroxide value determinations. Titration analyses are a way of testing the quality of various food types. The peroxide number or value is a good measure of the amount of damage suffered by the sample (storage, oxidation by light or temperature effects). The test requires...Read More

Wet scrubbing is the most common method to clean the flue-gas. Metrohm Applikon Process Analyzers are used to measure the calcium and sulfate content in several stages of the scrubbing process. Flue-gas desulfurisation (FGD) The flue-gas desulfurisation (FGD) is used during the incineration process of waste materials. It is one...Read More

Prevention is better than a cure. Most people schedule regular health and dental check-ups throughout the year. Knowing the weaknesses in a person’s body allows taking measures to prevent a serious and possibly long-lasting illness. Even if something does go wrong, a well-documented patient history might mean the difference between...Read More

NEW: V rotor for fibrous samples. The complete homogenisation of fibrous food samples is a difficult task as fibres can pass the apertures of the bottom sieve in vertical orientation. The use of the new V rotor with the SM 300 significantly improves the homogenisation of fibrous materials. Its special...Read More
