Description:
An innovative approach is presented for reducing analysis times of cynuric acid in swimming pool waters by high performance liquid chromatography (HPLC). The HPLC method exploits the unique selectivity of porous graphitic carbon (PGC) to fully resolve within 10 minutes cyanuric acid from other pool interferences. By carefully timing the injections, multiple injections can be made before the end of the initial chromatographic run, more than doubling sample throughout. The method utilizes a 50 mM of a phosphate buffer (pH 9.1) and 5% methanol (v/v) with UV detection at 213 nm. his approach yielded run times rivaling those of the fastest methods using silica columns, and with the benefit of longer column lifetime and increased sensitivity.
