The key feature of the LCU is controlled evaporation of a liquid flow into a gas stream to produce defined trace gas concentrations for calibration. This flow is only a few µl per minute. A flow controller for such micro flows needs to have an equally small dead-space in the order of a few µl, which we could not find in existing solutions. Therefore, a micro-pump, a micro-flowmeter, and a micro-processor board have been combined into the active Liquid Flow Controller that satisfies the low dead-space and is in addition self-aspiring, greatly facilitating the sample handling.
On December, 16th, 2014 Lukas’ diploma thesis has been recognized with the “Wissenschaftspreis” (Science Award) of the Austrian Chamber of Commerce (Innsbruck, Austria). Every year a jury selects outstanding and innovative academic projects with an economic impact.
