Abstract
A shock tube is a device in which a shock wave is normally formed by the rupture of a diaphragm, which divides a gas at high pressure from a test section containing the species of interest at a lower pressure. The shock wave brings the test gas virtually instantaneously to a known high temperature and pressure, maintains that condition for a time and then is supplanted by an expansion wave which cools the sample rapidly. During this time, the test gas can be studied by continuous sampling, for example to a time-of-flight mass spectrometer or alternatively sampled at the end of process by gas chromatography or other appropriate analytical techniques. Here, we discuss both methodologies and show with examples the benefits of both approaches.
