In a method for sampling a continuous liquid flow, the liquid flow is supplied to a surface along an input flow path. The liquid flow is sampled by forming a sample droplet from a portion of the liquid flow. The sample droplet is moved along an analysis flow path to a processing area of the surface,...http://www.google.es/patents/US7329545?utm_source=gb-gplus-sharePatente US7329545 - Methods for sampling a liquid flow
