    摘要: Disclosed is a method of determining the presence of an analyte of interest by means of a detection of a reaction product between the analyte of interest and a reactant, the method comprising extracting the analyte of interest from a complex sample matrix; transferring the analyte of interest to an initial reaction mixture; performing a background measurement on the initial reaction mixture comprising at most a negligible concentration of the reaction product, wherein the reaction conditions present in said initial reaction mixture at least reduce the reaction rate of the formation of the reaction product such that the background measurement can be performed without a measurable change in said negligible concentration; altering the reaction conditions in the initial reaction mixture to accelerate said reaction rate; continuing said reaction until the concentration of the reaction product has stabilized; performing a second measurement on the resultant reaction mixture to obtain a signal correlated to said concentration; and determining the presence of the analyte of interest from a difference between the background measurement and the second measurement. In a preferred embodiment, the analyte of interest is Propofol (2,6-di-isopropylphenol), and the reactant is the activated Gibbs reagent (2,6-dichloroquinoneimine).
