The shock wave structure in gas-particle mixtures has been investigated by measuring density profiles of the gas and number density profiles or the particles for shock Mach numbers below Ms 1.2. The measured profiles are compared with theoretical results. The experiments have been performed with a vertically mounted shock tube. For the generation of weak shock waves the usual diaphragm has been replaced by a pneumatic valve. A laser differential interferometer was used to measure the gas density and the number density of the particles was determined by extinction measurements.
