Abstract: A test strip construction includes a test strip having a testing region bearing a chromogenic reagent to detect the presence of a substance in a fluid test sample. A supporting member is attached to one end of the test strip in a manner such that the testing region is remote form the attachment point and is free from any contact with supporting member. When dipped into the test sample the test strip can flutter away from the supporting member to allow for full contact between that the testing region and the test sample. When removed from the test sample the supporting member provides a consistent background for observation of color changes of the reagent.

Abstract: A one-step integral analysis unit for the direct analysis of ammonia, wherein all necessary reagents are located in a single reagent pad comprising an indicator layer and an absorbent layer. The indicator comprises an ammonia indicator embedded in a continuous phase of a hydrophobic polymer so that gaseous ammonia, but not aqueous solutions, can penetrate the embedding polymer and reach the indicator. The second absorbent layer is buffered with hydroxide to maintain the equilibrium concentration level of ammonia to obtain best test color change results. The absorbent layer is attached to a plastic carrier and the indicator layer is attached to the absorption layer.
