Composition, which includes a dye that changes color when contacted with a suitable amount of an organic substance, in conjunction with a matrix, paste, support or web, can indicate visually or photometrically the presence of the organic substance. An organic spill absorbing material may be present. For instance, the dye may be selected from the class of anthracene, azo, anthraquinone, pyrazolone, and quinone dyes, and be hydrophobic and organic oleophilic. For an example, the dye may be Oil Red 'A.' The matrix, paste, support or web may include a microfiber cloth, which may be coated with an adhesive for attachment of the dye, and/or include a water-dissolving paper which may envelope the dye. A device for ascertaining whether an organic substance is present includes the dye or composition with the dye at a certain locale, and a light-transmissive pathway in communication with the location and a detection site external the location. A spectral instrument may be included for the detection, and a remote monitor site may be in communication with the instrument. Various organic substances can be detected, to include oils and gasoline.

Visual spill indicator

A method to condense or coalesce matter is carried out by providing a suitable, narrow passageway for throughput of matter in a vapor state, and passing the matter in a vapor state through said passageway, under conditions such that the matter is coalesced into a more ordered state. Also, a matter coalescing apparatus has a hollow housing in communication with at least one of--(A) a plurality of suitably narrow hollow passageways and (B) a suitably narrow, elongately hollow, matter-coalescing passageway--for throughput of matter to include as a vapor therein. Consequently, highly efficient yields of coalesced matter, to include liquid coalesced from vapor, even under only mild vacuum or at about ambient atmospheric pressure can be obtained. This is especially so with respect to oils, where yields as high as 95 percent or greater can be provided hereby. The invention can be practiced under such outstanding yield efficiencies without a general need for significant external cooling.
