A fluid path system includes a vial containing a pharmaceutical product therein. A dissolution fluid path is also included in the fluid path system, the dissolution fluid path having an output end in fluid communication with the vial and an input end attached to a pressure vessel containing a dissolution medium. A delivery fluid path is also included in the system having a first end hermetically attached to the vial to transport therefrom a mixture of dissolved pharmaceutical product and dissolution medium and a second end connected to a receiving vessel to receive the mixture. A dissolution fluid path valve is positioned between the pressure vessel and the dissolution fluid path to control flow of the dissolution medium, and a delivery fluid path valve is also included in the fluid path system to control flow of the mixture from the delivery fluid path to the receiving vessel.

A method and apparatus for preventing the formation of leachable mercury in mercury arc vapor discharge lamps is provided which comprises providing in the lamp structure an effective amount of a silver compound, gold compound, or combination thereof.

Control of leachable mercury in mercury vapor discharge lamps

The formation of leachable mercury upon disposal in a landfill or during TCLP testing of mercury vapor discharge lamps is substantially prevented by incorporation of an amount of gelatin or a degradation product of gelatin which is effective to substantially prevent formation of ferric and cuprous compounds responsible for forming leachable mercury compounds.

Control of leachable mercury in fluorescent lamps by gelatin

A method and apparatus for preventing the formation of leachable mercury in mercury arc vapor discharge lamps which comprises coating at least one of the metallic components of the mercury arc vapor discharge lamps with at least one noble metal coating.

Control of leachable mercury in fluorescent lamps

The formation of leachable mercury upon disposal in a landfill or during TCLP testing of mercury vapor discharge lamps is substantially prevented by incorporation of an amount of dehydroascorbic acid or a degradation product of dehydroascorbic acid which is effective to substantially prevent formation of ferric and cuprous compounds responsible for forming leachable mercury compounds.

The formation of leachable mercury upon disposal or during TCLP testing of mercury vapor discharge lamps is substantially prevented by adding soluble copper salts which are capable of being reduced to elemental copper which deposits on aluminum and other metal surfaces thereby inhibiting formation of oxidized forms of mercury by chemical reaction or amalgamation.

Control of leachable mercury in fluorescent lamps by addition of copper compounds

The formation of leachable mercury upon disposal or during TCLP testing of mercury vapor discharge lamps is substantially prevented by maintaining the amount of elemental iron at a level which is at least about 100 to about 1000 milligrams per kilogram of the total weight of lamp material.

Control of leachable mercury in fluorescent lamps by iron addition

The formation of leachable mercury upon disposal or during TCLP testing of mercury vapor discharge lamps is substantially prevented by maintaining the amount of elemental iron at a level of less than about 1.1 milligrams per kilogram of total lamp material.

Method to control leachable mercury in fluorescent lamp

The formation of leachable mercury upon disposal or during TCLP testing of mercury vapor discharge lamps is substantially prevented by incorporation in the lamp structure or in the test solution of an oxygen scavenger.

Oxygen control agents for fluorescent lamps

The formation of leachable mercury upon disposal or during TCLP testing of mercury vapor discharge lamps is substantially prevented by incorporation of an organic or inorganic metal completing agent in the lamp structure or in the test solution.

Complexing agent control of leachable mercury in fluorescent lamps

The formation of leachable mercury upon disposal or during TCLP testing of mercury vapor discharge lamps is substantially prevented by incorporation of an antioxidant in the lamp structure or in the test solution.

Antioxidant control of leachable mercury in fluorescent lamps

The formation of leachable mercury upon disposal or during TCLP testing of mercury vapor discharge lamps is substantially prevented by incorporation of a pH control agent in the lamp structure or in the test solution to provide a pH of about 5.5 to about 6.5.

A. parasiticus is employed to hydroxylate 2'-hydroxyterphenyl compounds to terphenyltriols, which can be used to form branched polycarbonates. The hydroxylation reaction is enhanced by maintaining a sufficient amount of a carbon source in the culture medium-reaction medium to maintain the ammonium level below 300 ppm. during the bioconversion phase. Employment of a mutant strain of A. parasiticus which was isolated following ultraviolet light mutagenesis to reduce its tendency to produce aflatoxins is preferred.

Fungal strain used to make 2',4,4'-m-terphenyltriols

A. parasiticus is employed to hydroxylate biphenyls or terphenyls. The hydroxylation reaction is enhanced by gradually adding a carbon source to the culture medium-reaction medium, preferably in an amount to maintain the ammonium level below 300 ppm. during the bioconversion phase. Employment of a mutant strain of A. parasiticus which was isolated following ultraviolet light mutagenesis to reduce its tendency to produce aflatoxins is preferred.
