| Abstract: | A method for the direct determination of ATP that exhibits reasonable sensitivity, and responds to very few interferants, has been developed. The chelation-enhanced fluorescence between N-(anthracen-9'-yl methyl)tris(3-aminopropyl) amine and adenosine 5'-triphosphate is utilized in this determination. The method was tested in batch and flow-injection analysis (FIA) modes. The typical detection limit for FIA determination of ATP is 1 muM, with a linear range of 0.5-100 ppm. A typical relative standard deviation at 20 ppm is 2.3%. |
