摘要： A flow-through rack assembly (14) includes porous hangers (44) which support items to be decontaminated within a decontamination chamber (12). A plurality of nozzles (16) spray a decontaminant fluid, such as peracetic acid, over the items. The rack assembly includes tubes (42) which convey a portion of the decontaminant fluid under pressure to internal channels (52) of the porous hangers. The fluid permeates the hanger surface, flowing over regions of the items which are in contact with the hangers. The rack assembly ensures decontamination of those regions which may be otherwise inaccessible to fluid sprayed from the nozzles.

摘要： The present invention is directed to a biguanide-containing disinfecting solution containing a particular type of poloxamine for stabilizing a polymeric biguanide. The poloxamine surfactant comprises at least about 90 weight percent of poly(oxyethylene) and poly(oxypropylene) segments, in one or more copolymer chains, wherein the weight average molecular weight of said surfactant is from about 10,000 to about 30,000 and wherein at least about 70 weight percent of said poly(oxyethylene) and poly(oxypropylene) segments are poly(oxyethylene) segments, and wherein the HLB value is at least 27. The method of the present invention comprises cleaning and disinfecting a contact lens with the above-described solution. Products according to the present invention provide enhanced cleaning while maintaining biocidal efficacy.

摘要： A method is described for precisely controlling chlorination of wastewater and chloramination of drinking water. The method involves analyzing the water for the presence of residual monochloramine without interference of dichloramine, organic amines, organic chloramines or nitrites. A color-forming reagent is added to a sample of the water which will develop a colored compound upon reaction with monochloramine, after which the sample may be colorimetrically analyzed to determine the amount of monochloramine present. The method is very accurate and avoids the problems associated with conventional tests used for chlorination control.
