Optimizing the primary particle size distributions of pressurized metered dose inhalers by using inkjet spray drying for targeting desired regions of the lungs

“…Previous studies 39,40 showed much narrower aerosol particle size distributions for pMDIs containing 5 µm polystyrene particles than the pMDI in this study that contained 4.99 µm monodisperse salbutamol sulphate particles. Then a smaller GSD might have been achieved in this study, if the formulation would have been optimised further in terms of surfactant type, valve size and the volume of spacer.…”

Biological and chemical hazards in water-mix metalworking fluids and mists

“…A drawback to using a sampler that requires a liquid medium is that drawing air into a liquid for prolonged periods of time can cause evaporative loss of the sample medium (Kesavan et al, 2010). A reduction in the level of sample medium has been shown to reduce the efficiency of the sample unit, in particular with the SKC Liquid impinger units.…”
