Abstract

Abstract: We present a new device for quantifying gases or gas mixtures based on the simple principle of bubble counting. With this device, we can follow reaction kinetics down to volume step sizes of 8–12 μL. This enables the accurate determination of both time and size of these gas quanta, giving a very detailed kinetic analysis. We demonstrate this method and device using ammonia borane hydrolysis as a model reaction, obtaining Arrhenius plots with over 300 data points from a single experiment. Our device not only saves time and avoids frustration, but also offers more insight into reaction kinetics and mechanistic studies. Moreover, its simplicity and low cost open opportunities for many lab applications. Abstract : Die Blase platzen lassen : Schnelle, einfache und akkurate Arrhenius‐Graphen können in einem einzelnen Experiment erhalten werden. Durch die Verwendung eines neuen Aufbaus zur Quantifizierung von Gasen oder Gasmischungen, der auf dem einfachen Zählen von Blasen beruht, ist es möglich, Reaktionskinetiken mit Volumenschritten von nur 8–12 μL zu verfolgen.
