HIGH STABILITY

GAS MIXING

MICRO FLOWS

TARGET OF THE PROJECT

Vapour concentration control of solvents by mixing dry nitrogen with one bubbling through a solvent of interest (water, ethanol or other organic solvents).

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.

PRECISION - GAS MIXTURE

Flow Stability

Thanks to our revolutionary method every gas flow has a great stability making possible to have a stable flow also for lower flow-rate.

Time Savings

Easier setup management of the hardware. Easier setup management of the software.

Micro-Flows. No Cut-Off

Our GB2000 Series allows the Humboldt U. to control the flow in all the calibration range, from 0,1 ml/min to 2000 ml/min with NO cut-off.

Without MCQ?

The previous solution didn’t help to get progress for the research. So the Humboldt U. moved to MCQ Instruments,

Software Automation

Thanks to our Software PRO Version and its option "Automatic Program", now the Humboldt University of Berlin can bring forward experiments in automation.

Successful Achievement

Replace an operator who previously controls the valves manually with our Automatic Gas Mixing Solution.
