Our worldwide supplier network

We maintain a worldwide network of suppliers in order to always have efficient and innovative products in our program. For many partner companies we have taken over exclusive sales and support obligations for Germany and partly also Austria and Switzerland. With others, we are linked by a cooperation for individual products or product areas. We make one fundamental demand on each of our cooperations: the products must provide a very special benefit for our customers, either on their own or in combination with our services. Here you will find a list of our suppliers and manufacturers. Use the links to visit their homepage.

Axel Semrau

What began as a distributor for gas chromatographs quickly led to a company that also develops its own instruments and software solutions. The first step in this direction was taken by the Odorization Control Division. With our own hand-held and stationary measuring instruments we are the world market leader in the field of natural gas analysis and odorant control. Through our sales activities in the chromatography sector, we learned about the users’ problems. We use the experience we gained during the development of the ODOR instruments as a basis for finding new solutions for chromaography as well. Especially under the brand name CHRONECT complex automation solutions for the laboratory are created. Decisive for this workstation is above all the software CHRONOS, which was developed by us for a more efficient control of the sample preparation. It also enables simultaneous analysis, as it can be combined with many common evaluation programs. Most new developments are created in close cooperation with renowned contract laboratories or established research institutes.
