Quality control in our excellent laboratory

Analytical competence from long-term experience

Right from the beginning the composition of hops plays a pivotal role for hop-traders and farmers. NATECO2’s laboratory has always been one of the front-runners in analysing the complex hop matrix. The long standing experience of our lab-team and the resulting in-depth know-how in analyzing natural substances guarantees a broad competence for our daily analytical duties and challenges.

Services of our laboratory

The high demands of product- and process-safety are continuously guaranteed, controlled and improved by our internal high-tech laboratory. Our laboratory is the center of quality control for both our shareholders and we analyze over one third of the worldwide hop harvest. Our core competence is not only the detection of important substances in hops (bitter- and aroma-components, polyphenols), but also the determination of a variety of ingredients in a wide range of natural materials such as carotenoids, vitamins, terpenes, xanthines or fatty acids. Additionally, our lab-team has enormous expertise in the detection of pesticide residues. Our know-how in this area as well as our state-of-the–art equipment enables us to determine all relevant agents in the nano-mol range.

In order to enable the detection of a multitude of different ingredients, our laboratory is fully-equipped to a high technical standard. Our main analytical focus is in the fields of spectroscopy (UV/VIS/NIR) and chromatography.
