| Research Abstract |
High-sensitive liquid-electrode plasma atomic emission spectrometry(LEP-AES) are studied. T the limits of detection(LOD) were investigated in various condition of accumulation time, material of the chip, and the sample flow. It was found that the long accumulation using quartz chip with sample flow was very effective to improve LOD. Authors suggested that this was because bubbles remaining after each plasma pulse were removed from the narrow channel by sample flow, resulting high reproducible plasma generation, to enable high accumulation effect. Finally, LOD were calculated from calibration curve, to be 0. 00052μmg/L for Cd and 0. 019. 0μmg/L for Pb at optimized condition. Sub ppb level LOD was achieved for Cd.
