Different valency chlorine species analysis by non-suppressed ion-chromatography with double cell quartz crystal
1New Materials Research Institute, Hunan University, Changsha 410082, People's Republic of China.
Abstract:
A non-suppressed ion-chromatographic assay combined with a novel double cell quartz crystal (DCQC) detector is developed for analysis of different valency chlorine species including chlorite, chloride, chlorate, hypochlorite. The retention characteristics of the anions are discussed. The chromatographic system involves the use of a Shimadzu Shim-pack IC-A1 anion analysis column with 0.5 mM potassium acid phthalate (KHP), pH 6.7, as a mobile phase. The DCQC detector has a low temperature coefficient and a high conductance sensitivity independent of the background from 7.2 to 2500 muS. The analysis of sample is completed without the use of an ion suppression device.
