Chemical system with self-timing indicator
First Claim
1. A luminescent composition, comprising:
- a selected luminescent marker comprising a first phase of the luminescent composition;
anda selected ionizing agent comprising a second phase of the luminescent composition, wherein the selected luminescent marker exhibits luminescence for a predetermined indicatory period responsive to intermixing of the first phase of the luminescent composition with the second phase of the luminescent composition, and wherein a luminance intensity remains at least at a threshold intensity during predetermined indicatory period.

Abstract
A luminescent composition, with a luminescent marker and a ionizing agent exhibiting luminescence for an indicatory period once intermixed, and with luminance intensity remaining at a threshold intensity during indicatory period. Luminescence also can be exhibited responsive to responsive to excitatory light applied to the composition. The luminescent marker includes a coumarinic compound and the ionizing agent includes an ammonium base. Antimicrobial agents are included. A luminescence measuring apparatus includes a photoemitter and a photodetector responsive to an emissive light induced by photoemitter. An optical filter can be used with the photodetector. A two-phase composition dispensing apparatus includes a first phase reservoir, a second phase reservoir, a mixing nozzle, and a dispensing mechanism.
