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).

A connector includes an insulating housing having a rear wall of which a front side extends forward to form a tongue portion and a back side defines a concave groove in accordance with the tongue portion. The tongue portion defines a plurality of terminal grooves. A plurality of terminals each has a fixing portion fixed in a rear of the terminal groove with a rear end thereof further projecting into the concave groove, a contact portion disposed in the terminal groove, and a soldering tail stretching outside the insulating housing. A water-proof member is formed in the concave groove by injecting molten water-proof colloid in the concave groove to seal up intervals between the fixing portions of the terminals and inner sides of the rears of the terminal grooves. A metal shell is molded in the insulating housing.

A method of manufacturing a semiconductor device and a semiconductor device made by the method is disclosed. The method comprises forming a buried N+ layer in an upper portion of a P-type substrate; performing ion implantation on the buried N+ layer; annealing the buried N+ layer; forming an epitaxial semiconductor layer on the buried N+ layer through epitaxial deposition, wherein, an upper portion of said epitaxial semiconductor layer and a portion underlying said P+ region of said epitaxial semiconductor layer are doped to form a P+ region and an N− region, respectively. Increasing the ion implant dosage of the BNL layer, adjusting the method of annealing the BNL layer to increase the width of the BNL layer, or increasing the thickness of the EPI layer, reduces the vertical BJT current gain and suppressed the substrate leakage current.
