Chiesi Plume Temperature Measurement of MDIs

Methods to determine the temperature of plumes emitted from chlorofluorocarbon (CFC) and hydrofluoroalkane (HFA) metered dose inhalers (MDIs) have been previously been published1-3. This paper presents data obtained using a new experimental set-up (Plume Temperature Tester Model PTT 1000, Copley Scientific, UK) that measures plume temperature within a sampling tube constructed to the USP induction port entrance dimensions (USP 35, Apparatus 1, 2, 4 & 5).
