Residues & Contaminants


Residues & Contaminants

Our solution package of parameters to be analyzed comprises residues & contaminants and reflects an important part of consumer protection. Many contaminants pose toxic, cancerogenic or teratogenic risks.

In case of our analyses methods we – amongst other things – focus on conventional technical procedures and lipophilic matrices. Apart from multi-methods, we however always also offer corresponding analyses of single active ingredients, depending on application.

Polycyclic Aromatic Hydrocarbons (PAHs)

Organic, fat-soluble contaminants – occur mainly in cases of incomplete combustion processes, which enables penetration of environment.

Plant Protection Agents (Pesticides)

Chemical plant protection is an integral part of modern agriculture. Legal provisions regulate maximum values in consumer products. By means of high-end analytics (LC- and GC-MS/MS), up to 600 substances can be identified in one screening, via a multi-method with two analytical devices.

Polychlorinated Biphenyls (PCBs) and Dioxins

Additives, used as softening agents in coatings, plastics etc.
Accumulations in fat-soluble matrices often result in penetration of the environment.


Mould fungus toxins, which can potentially emerge on the field and during storage.
A known group of Mycotoxins are Aflatoxins. Impacts of mould fungus toxins range from acute toxicity to a cancerogenic effect.

Pyrrolizidine Alkaloids (PAs)

Natural toxins of plants, acting as a defensive compound against herbivores. Toxic and carcinogenic impact on human organism.
Since July 2022 maximum values for 21 Pyrrolizidine Alkaloids have been set at EU-level.

Softening Agents

Additives used for production of plastics, in order to generate elastical characteristics in plastics materials.
Following Esters belong to the most important substance groups: Phthalates, Citrates or Adipates.

Residual Solvents

Solvents are partially used for extraction or cleaning purposes.
There are defined maximum levels for various food products.

Heavy Metals

For instance Arsenic, Antimony, Lead, Cadmium, Mercury, Chromium and Nickel belong to legally regulated heavy metals.

Upon request, we’d be happy to provide you with an excerpt of analysis parameters of individual analysis methods.
