This patent describes an article of manufacture an optrode for chemically sensing halogenated hydrocarbons comprising the elements: a capillary tube capped at one end by a semipermeable membrane of porous membrane; a fiber optic attached at a distal end thereof to a second end of the capillary tube by attaching means. The fiber optic extends into the capillary tube. A proximal end of the fiber optic is connected to an illumination source and a detector means; a column of a first reagent comprises pyridine or a pyridine derivative disposed in the capillary tube adjacent the capped end; and a column of a second reagent comprises an alkali disposed in the capillary tube adjacent to and in contact with the column of the first reagent such that a surface of contact between the alkali and the first reagent is adjacent the distal end of the fiber optic.
