Genetically Modified Organisms (GMO)



The issue of GMOs has over the past years evolved to become a very complex set of tasks. Old and new approvals of GMO plants in different countries that are not always conforming to EU approvals play their role in regards to marketability. In order to make a sound appraisal we use the following scheme to clarify the situation:

Pyrrolizidine alkaloid containing plants and their pollen



As part of the research project AiF 16223 BG (supported by the German Ministry of Economics and Technology (via AiF) and the FEI (Forschungskreis der Ernährungsindustrie e.V., Bonn) a range of pyrrolizidine alkaloid containing plants and their pollen were collected and photographs were prepared. Additional information on origin, habit and dispersal are provided. This data collection can be used by e.g. bee keepers and others to facilitate the identification of pyrrolizidine alkaloid containing plants and their pollen.

Coffee, tea and cacao

Coffee analysis


In Germany more than 164 million cups of coffee are consumed daily – which amount to more than mineral water and beer consumed. Besides Coffee we are also analysing tea, cacao, chocolate drinks and cappuccini according to their respective quality standards.




Analysis of pharmaceuticals


There are no products that are subject to such strict inspections like pharmaceutics. We support our customers in all requests concerning quality control of pharmaceutical products and their raw materials. Besides analytical laboratory services consultancy for analytical and legal issues becomes increasingly important. In corporation with the customer qualified GMP representatives (Good manufacturing practices) support the costumer’s internal preparation for audits by legal authorities.




Analysis of Cosmetic Raw Materials


We offer tailor fit solutions for analyses of cosmetic ingredients and provide qualified safety assessment services for manufacturers, distributors and suppliers. Furthermore we check if the products labelling is according to the law regulations and determine the purity and quality of essential oils, aromas and perfumes.
