Environmental analysis

The environmental challenges require internationally accepted standards, in which limits and test methods are defined. Metrohm instruments and applications comply with a lot of international environmental standards.

Substances introduced into the environment are distributed among the environmental compartments water, soil (sediment), and air, as well as among the organisms living in them (biosphere). Only if we know the type and quantity of these contaminants can we protect the environment and its inhabitants.


A lot of the 100,000 compounds produced on a large industrial scale end up in our water supplies. A host of regulations and standards protect our water resources.

In step with regulatory compliance, we offer you the appropriate instrumentation and application for all types of water samples.

Air is a heterogeneous mixture of finely dispersed, solid or liquid particles in a gas (air). Sampling includes both filter and continuous methods. While the first type is offline and supplies data over longer accumulated periods, powerful continuous samplers work online. They are directly coupled to one or more robust analyzers – inline of course.

Petrochemical and biofuel analysis

Crude oil is a highly complex mixture of hydrocarbons. Through desalting, distillation, and conversion, it is transformed into fractions of higher-quality hydrocarbons such as paraffins, aromatics, naphthenes, and olefins. Different ratios of these so-called PIANO compounds are blended to yield different fuel and lubricant types. Increasingly, fossil fuels are blended with biofuels.

Both blending and refining processes are demanding and require precise and reliable analysis. Regardless whether you deal with fossil or biogenic products, we are your specialist when it comes to analyzing them in accordance with international standards.

Fuels – Paraffins, aromatics, naphthenes, olefins

Paraffins, aromatics, naphthenes, and olefins are the main petrochemical classes from which the hundreds of compounds that make up volatile and semivolatile fossil fuels (e.g., gasoline and diesel) originate. The complex composition of fuels requires fast and accurate analysis methods, both in the lab and the process.

Pharmaceutical analysis

Pharmaceutical analysis guarantees drug safety by providing information on the identity, content, quality, purity, and stability of pharmaceutical products using analytical chemistry. Metrohm offers you a broad range of instruments and applications for quality control and for monitoring and improving drug manufacturing. With myriads of pharmacopeia-compliant analysis methods, we are your qualified partner for all chemical-pharmaceutical analysis issues and analytical method validations.

In accordance with international pharmacopeias and various guidelines, Metrohm offers you analysis for active pharmaceutical ingredients (APIs), excipients, impurities, pharmaceutical solutions as well as pharmaceutical starting materials, and finished pharmaceutical products (FPPs). Additionally, we provide numerous wet chemical methods for atline and online process control as well as inline monitoring methods for assuring cost-effective manufacturing processes that satisfy all regulatory demands.

Active pharmaceutical ingredients (APIs)

APIs are used to cure, alleviate, prevent, or identify illnesses and diseases. They are present in small quantities and aim at restoring physiological functions in human beings. In international pharmacopeias, a list of monographs provides detailed descriptions of test methods, tests, and requirements.

Impurities are mainly introduced from the starting materials used and/or during synthesis of the active pharmaceutical ingredients. They are monitored according to both the directives of the ICH (International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use) and the pharmacopeias. Even small concentrations of impurities can have significant side effects.

Pharmaceutical manufacturing process

Successful process monitoring relies to a great extent on the latest methods of ion analysis and spectroscopy. While the former – mostly wet chemical methods – are preferably measured online and atline, near-infrared spectroscopy (NIRS) is the ideal tool for inline monitoring, particularly in the light of the FDA’s PAT and QbD initiatives.

Food and beverage

Today’s food and beverages (F&B) are much more than just simple "organic fuels" needed for survival. Beyond their nutritive value, they are consumed for their taste or flavor. Increasingly, they are also a source for maintaining health and enhancing our well-being via high-quality nutrition. At the same time, with an ever-increasing number of processed foods, food quality and safety aspects are becoming more important. All the more because foods are highly complex materials – prone to degradation and contamination – that contain myriads of compounds.

Analytical chemistry makes sure that consumers obtain safe and sanitary food in compliance with regulatory requirements. Nutrient information, food traceability, and protection against fraud are further challenges. From the process point of view, analytical chemistry supports the manufacturer to improve yields and optimize quality by offering robust, efficient, and sensitive instrumentation. Whatever your concern is, Metrohm is the right partner.

Beverages and drinking water

Although it contributes no calories to our diet, water is the most important life-sustaining resource for most organisms. It is the main constituent of beverages and it can be found in almost all foods. If somebody knows how to analyze water and beverages it’s Metrohm; more than 270 applications are testimony to this expertise.

Milk and dairy products

Milk contains nearly all nutrients necessary to survive: fat, high-quality protein, carbohydrates, vitamins, and minerals. It is our first food and as a raw material offers incredible refinement possibilities. Dairy products are probably the most diverse of all food groups. Because of the protein and fat matrix, milk and dairy samples require sample preparation. Metrohm instruments were developed in response to these tedious and error-prone sample preparation tasks. Our instruments are fast, accurate, and economical.

Edible fats and oils

Fats and oils are a principal part of our nutrition and serve a lot of functions, from adding flavor and texture to emulsifying and acting as a heat transfer medium. For determining the nutritional value of fat- and oil-containing foods (margarine, mayonnaise, noodles, nuts, etc.), the determination of fat parameters (e.g., iodine, peroxide and acid value) as well as the ion and water content is crucial. Since fats and oils are prone to deterioration, the determination of the oxidation stability is a must. These analyses are part of Metrohm’s core competence.

Energy and power plant analysis

Growing populations – about 80 million every year – and industrializing countries create huge needs for electrical energy. According to the International Energy Agency (IEA) the global energy demand will increase by about 65% by 2035. A major fraction of the required energy will continue to be provided by thermal – mainly fossil fuel-fired and nuclear – power plants. "Renewable" energy sources such as photovoltaics (PV) will be another backbone of our energy supply. Putting renewable energy on the grid requires powerful energy storage and conversion devices, such as supercapacitors, batteries, or fuel cells.

For these technologies to work at maximum efficiency, all constituents of power installations have to perform at the highest level: be it the monitoring of the water chemistry in thermal power plants, the wet chemical processing of solar cells and battery electrolytes, or electrochemical measurements of energy storage devices, Metrohm provides the adequate analytical solution.

Power plant analysis

The bulk of electricity is generated by fossil-fuel or nuclear power plants. These methods of energy production involve water-steam circuits that drive turbines. The extreme conditions in the reactors are conducive to corrosion, which reduces the power plant’s output, causes downtimes, or even jeopardizes the power plant’s safety.
This is why monitoring of the water chemistry in power plants is of paramount importance. Read more about the challenges power plants are facing and what solutions Metrohm can provide:

Photovoltaic (PV) cells or solar cells convert energy of light directly into electricity. Common materials consist of monocrystalline or polycrystalline silicon, thin-film solar cells, or the third-generation multilayer cells.

Besides fully integrated bath analysis for crystalline silicon, thin film (CIS/CIGS, CdTe, a-Si), and other cell types, we offer real-time methods for controlling the etch rates and surface characteristics. Additionally, we provide instruments and methods for straightforward analyses of (photo-) electrochemical processes in dye-sensitized and all other solar cells.


Energy storage and conversion

Energy demand and supply seldom coincide. In particular, renewable energy cannot be stored very efficiently and is therefore often not at hand when needed. Electrochemical, chemical, and electrical energy storage (EES) systems – mainly batteries, supercapacitors, and fuel cells – are promising means to balance availability and energy demand.

Metrohm is electrochemistry, and all over the world researchers use our sophisticated instruments for production, characterization, and development of materials and cells.
