ABSTRACT:
Apparatus for chemical detection includes a cap for coupling with a sample vial containing a sample. The sample includes at least one chemical to be detected. The cap includes a reagent vial which contains a liquid reagent. The reagent vial includes a membrane which substantially retains the liquid reagent and which is substantially permeable to the chemical to be detected. The reagent vial can be opened to allow the chemical to permeate and enter the reagent vial and closed to substantially prevent the chemical from permeating the membrane and entering the reagent vial. In some embodiments, the reagent vial is opened and closed by movement of the reagent vial. In some other embodiments, the reagent vial remains stationary while a device moves to open and close the stationary reagent vial.
