Abstract
Method and apparatus for parallel dispensing of powder samples is described. Powder samples are dispensed into at least two powder sample holders, each said sample holder having a through passage which preferably generally tapers from a first aperture through which powder is introduced into said passage and a second aperture through which powder, when permitted to do so, flows from said passage. The lower apertures of the sample holders are preferably sealed using a resilient film. The powder samples are dispensed by substantially simultaneously perforating the film covering each aperture and agitating the powder samples to cause them to flow from their respective sample holders. Also disclosed are a method of generating a library of powder samples and a library of powder samples.
