Description of the Application.
Mixing of dry nitrogen with nitrogen bubbling through washing bottle filled with solvent of interest (e.g. water). In the example with water, this should allow to control relative humidity of our samples, i.e. sample cell. Water can be replaced onto other organic solvents. We are especially interested in precise control of slow flows, since the flow should flush a sample cell of a noise sensitive instrument. Therefore the GB2000 sounds like better choice.
The contamination of nitrogen one can actually smell simply as a kind of “plastic” smell. Nitrogen passing through e.g. PE pipes starts to smell after “plastic”. Therefore, it is essential for us to use rather inert materials. We are interested to keep our samples under certain humidity for over day or longer, therefore we are looking to replace operator who controls the valves manually onto an automatic mixing station, i.e. MCQ solution.

The Humboldt University of Berlin is divided into nine faculties, including its medical school shared with the Free University of Berlin, has a student enrollment of around 32,000 students, and offers degree programmes in some 189 disciplines from undergraduate to postdoctorate level. The university is known worldwide for pioneering the Humboldtian model of higher education, which has strongly influenced other European and Western universities.
