AIR SHUTOFF AGENT FOR AQUEOUS REAGENT AND AQUEOUS SPECIMEN, AND METHOD FOR STORING AQUEOUS REAGENT AND AQUEOUS SPECIMEN WITH STABILITY

摘要

An air shutoff agent for an aqueous reagent or an aqueous specimen (hereinafter, referred to as "aqueous reagent or the like" which comprises a s an effective component a mixture of a linear hydrocarbon and a silicone oil which is immiscible with the aqueous reagent or the like and has a lower specific gravity than that of the aqueous reagent or the like; and a method for storing the aqueous reagent or the like with stability which comprises placing the mixture over the surface of the aqueous reagent or the like. The placement of the air shutoff agent for an aqueous reagent or the like over a n aqueous reagent or an aqueous specimen results in the stable storage of an effective component in an aqueous analytical reagent and a component to be determined in an aqueous specimen, and the air shutoff agent has an advantageous characteristic that when the agent flows into a reactor of an autoanalyzer it does not soil the reactor.
