aQuantitative ions (). bCalibration curves with compounds concentration: 5, 10, 20, 50, and 100 ng L−1. cRSD: relative standard deviation, using IBMP as the internal standard. Compound concentration: 20 ng L−1. dWithout internal standard. Compound concentration: 20 ng L−1. eLOD: limit of detection was calculated on the basis of = 3, this value is a mathematical approximation. |
