Gas chromatography with mass spectrometry for the separation of organic mixtures

PAH analysis

Verification and analysis for industrial and environmental samples

Solutions for PAH analytics

Polycyclic aromatic hydrocarbons (PAH)  form a large group of organic compounds that occur naturally as well as due to human activity. As a consequence of their potentially carcinogenic and polluting characteristics, the monitoring and analysis of PAHs in various matrices such as environmental samples, foodstuffs and plastics is of crucial importance.

The analysis of PAHs is therefore strongly recommended for the verification of the safety, environmental sustainability and conformity of products and environmental samples. PAH analytics can be used to identify and minimise risks by ensuring that concentrations of these compounds are below the statutory limits.

At a glance: test methods for PAH analytics

In our accredited test laboratory, we rely on advanced technology and highly precise methods to identify and quantify reliably the presence and concentration of polycyclic aromatic hydrocarbons (PAHs). Here we utilise gas chromatography (GC)  in combination with  mass spectrometry (GC-MS). These methods enable us to measure precisely even very low concentrations of PAHs. As such, we offer the reliability and accuracy necessary for compliance with strict environmental and safety standards.

Challenges of PAH analytics

The challenges of PAH analytics are varied and complex due to the chemical diversity of PAHs and the different matrices in which they are analysed. Our expertise in the precise identification and quantification of individual PAH compounds, as well as our optimised laboratory processes, which effectively minimise the interference typical in varying sample materials such as soil, water or biological tissue, ensure the best results nevertheless.

Highly precise PAH analytics using GC-MS

This method is ideally suited to the analysis of volatile and semi-volatile PAHs as per the requirements of the AfPS standard. GC-MS features high sensitivity and precision that makes it possible to separate complex mixtures into their individual constituents effectively. After chromatographic separation, the PAH compounds are identified and quantified using a mass spectrometer. This technique ensures highly precise, dependable analysis results that comply with the strict scientific and regulatory requirements for PAH analytics

Applications for PAH analytics

PAH analytics has come to the fore in many sectors. Using GC-MS, PAH compounds in plastics, environmental media and many other samples can be identified and quantified. The PAH level is therefore an important indicator for identifying high concentrations at an early stage and guaranteeing high product safety.

Plastics industry

In the plastics industry, PAH analytics plays a crucial role in safeguarding product quality and safety. Because plastics are used in numerous applications, it is important they are free of harmful PAHs, in particular if they are used in contact with foodstuffs or in sensitive environments. Analytics helps to check for compliance with statutory requirements and to minimise the risk of harmful effects.

Automotive industry

The automotive industry uses PAH analytics to monitor emissions and to check materials used in vehicles. PAHs can be found in engine oils, exhaust gases and even in the plastics used. By means of regular tests, it is ensured that vehicles meet environmental standards and do not harm the health of users.

Water analytics

PAHs can enter watercourses by means of industrial waste water or due to accidents. Monitoring them in water resources is therefore essential to safeguard the quality of the water and to protect ecosystems.

Foodstuff analytics

In foodstuff analytics, PAH analytics is used to guarantee the safety of food. PAHs can occur while smoking or barbecuing foodstuffs; cocoa and chocolate can also contain PAHs. Analytics makes it possible to measure the concentrations of these compounds in foodstuffs and to ensure that the concentrations remain below the stipulated limits to protect the health of consumers.

Frequently asked questions about PAH Analytics

What is PAH analytics?

Polycyclic aromatic hydrocarbons (PAH) are a group of chemical compounds formed during incomplete combustion processes. The combustion processes can be due to natural causes, such as forest fires, or due to human activities, for instance power stations, industrial plants or road traffic. PAHs are found in many everyday environments: from smoked foodstuffs to exhaust gases and tar. Due to their potentially harmful effects – many PAHs are categorised as carcinogenic – the monitoring of their presence in the environment and products is essential.

What can be analysed using PAH analytics?

PAH analytics is relevant in a large number of application areas. Environmental samples such as soil, water and air are regularly tested for PAHs to monitor and manage pollution. In industry, raw materials and end-products, including plastics and chemicals, are analysed to ensure compliance with safety standards. Cosmetic products are also analysed to protect consumers against exposure to harmful amounts of PAHs.

What does the PAH level mean?

The PAH level provides information about the total concentration of polycyclic aromatic hydrocarbons (PAHs) in a specific sample. This figure is very important because it provides information about not only the presence of PAHs, but also their potential impact on the environment, human and animal health. An elevated PAH level signifies an increased concentration of PAHs, which can signify a greater threat for the environment and the organisms in this area. For this reason, the PAH level is an important quality indicator for the environment and an indicator for the potential risks that can emanate from PAHs.

Why is PAH analytics so important

The need for the strict monitoring and regulation of polycyclic aromatic hydrocarbons (PAHs) is due to their high persistence, bioaccumulation and toxicity. PAHs are therefore the subject of extensive regulations related to the protection of the environment with the aim of limiting their release and therefore minimising their negative effects on the environment and human health. The analysis of PAHs in foodstuffs, air, soil and water plays a central role here, because many of these compounds are known to be carcinogenic and mutagenetic, they can also have further harmful effects.
