Abstract:
1. A method of detecting the presence of microorganisms on a membrane, comprising: filtering a sample through a membrane, thereby capturing microorganisms in said sample on said membrane; rendering the ATP of said captured microorganisms accessible; providing a spraying device having a spraying station and a measuring station grouped together, said spraying station comprising a spraying bell, a nozzle for emitting a jet of droplets into a spraying chamber comprised by said bell, and an absorbent pad spaced from said membrane, said pad having a central opening; emitting in said spraying station said jet of droplets of a reagent capable of revealing the presence of ATP by luminescence towards said absorbent pad and said membrane, causing a portion of said jet of droplets to pass through said central opening and contact microorganisms on said membrane; and detecting in said measuring station the presence of microorganisms from the quantity of light emitted in response to the contact of said reagent with said microorganisms.
