QSI – Your partner for fast and flexible laboratory tests.

In recent years, there has been a steady increase in legal requirements and quality standards. Consumers expect a secure and high quality of the products they purchase, which are also expected to be free of harmful substances.

Increased awareness is certainly also based on enhanced consumer protection and information provided by consumer magazines.

We would like to take this awareness into account – and offer you our professional competence and qualification for recognized and independent analysis.

Our established quality management system helps us to comprehensively control investigations and processes to secure and maintain your analysis results.

Our daily work encompasses the analysis of products such as honey, coffee, tea, cocoa and other foods as well as raw materials from the pharmaceutical sector.

Our success story

In 1954, Dr. Herwarth Duisberg founded the Institute for Honey Research. He was the first in Germany to define parameters for the quality control of honey, which were laid down in various publications.

In 1976, Dr. Bela Talpay took over the management of the institute. In his publication “Specifications for Trachthonige (DLR 5,1985)” he defined the most important honey varieties that were imported to Germany at the time.

In 1989 Dr. Cord Lüllmann took over the management of the institute. In addition to analysing honeys from all over the world, he has expanded the company’s portfolio to include other food and pharmaceutical products. This broad spectrum of analyses was now also reflected in the new company name: QSI – Quality Services International GmbH.

Today, QSI is also involved in EU-funded projects worldwide aimed at improving the quality of end-consumer products.

By joining the constantly growing Tentamus Group of laboratories in 2013, QSI was able to further increase its analytical services and can cover an ever-increasing portfolio of products and analyses within the group.

By combining many years of experience and commitment, we ensure the two foundations of our quality policy: maintaining the resilience of our laboratory results in the context of daily routine examinations and our passion for analytical innovations. This is ensured not least by our motivated employees, who are qualified through internal and external training courses.
