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. Increased awareness is certainly also based on enhanced consumer protection and publications of consumer magazines.
We take this awareness into account – and offer professional competence and qualification for recognized and independent analysis.
Our established quality management system helps us to comprehensively control analyses and processes to secure your analysis results.
Our daily work encompasses the analysis of products such as honey, coffee, tea, cocoa, hemp and other foods as well as medical cannabis and further pharmaceutical raw materials. This scope also includes analyses under GMP conditions.
