Abstract:
1. A method of detecting a NO x compound in a wound, comprising: providing a sample from a wound, a first retention medium, and a chromogenic reagent; forming a first mixture comprising the sample and the chromogenic reagent under conditions that permit the reaction of a nitrite compound with the chromogenic reagent to form the colored compound; heating the first mixture; diluting the first mixture with an aqueous liquid; contacting at least a portion of the first mixture with the first retention medium; and detecting the colored compound retained on the first retention medium; wherein the first retention medium comprises a medium with ionic functional groups that interact with the colored compound; wherein the contacting at least a portion of the first mixture with the first retention medium occurs after the heating the first mixture and after the diluting the first mixture with an aqueous liquid.
