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.

L'invention concerne un procédé et un appareil pour distribuer en parallèle des échantillons de poudre : des échantillons de poudre sont distribués dans au moins deux supports d'échantillons, chaque support présentant un passage traversant qui, de préférence, se rétrécit généralement d'une première ouverture à travers laquelle de la poudre est introduite dans ledit passage à une seconde ouverture à travers laquelle poudre peut s'écouler dudit passage. Les ouvertures inférieures des supports d'échantillons sont, de préférence, scellées de façon étanche par un film élastique. Les échantillons de poudre sont distribués après perforation sensiblement simultanée du film recouvrant chaque ouverture et agitation des échantillons pour les amener à s'écouler de leur support respectif. L'invention concerne également un procédé de génération d'un répertoire d'échantillons de poudre et le répertoire d'échantillons de poudre.
