| Abstract: | A method for the determination of anions and cations in the mural painting plaster was developed by combination of dual channel ion chromatography（IC） with an auto-sampler. Detection limits for anions ranged from 0.01 to 0.03 mg/L and for cations ranged from 0.03 to 0.17 mg/L. The recoveries of added standards were 97 %~104% and the RSD of the peak area of analytes were lower than 2.4%. The analy- sis time was greatly reduced due to the parallel undergoing processes of auto-sampling and dual channel IC. |
