Abstract:
A kit containing three tablets is used in a process for testing for formaldehyde and/or glutaraldehyde in a sensitive, rapid, and simple manner that is practical even when glucose is present. A first tablet containing citrus acid and glycine hydrochloride (or like buffer and strong acid, respectively) is placed in the test solution (suspected to contain formaldehyde and/or glutaraldehyde) with a tablet containing the necessary reagents for developing color. These reagents include benzoylacetone or its derivatives, and ammonium acetate. A third tablet containing effervescing material is added, causing mixing of the solution. The third tablet typically is composed of sodium hydroxide and potassium carbonate. The yellow color (if formaldehyde and/or glutaraldehyde are present) produced by the reaction is compared to colors on a color chart, and thereby the approximate amount of formaldehyde and/or glutaraldehyde present may be determined.
