Method for chemical analysis

摘要: A chemical analysis test device for detection of a selected in biological fluid is disclosed wherein the preformed on rigid base containing well holding reagent and specimen sample to be tested. The positioned above concentration chamber cross-sectional area increases as distance from bottom increases. passage connects well. has generally hemispherical interior surface an opening thereof. strip wicking material secured interconnecting chamber. tested deposited contacts through paper wicks across treated with agent volatilize under test. volatilized concentrated by forced into contact stored well, producing visible color change passage, indicative content fluid.
