Development of a Sample-Preparation Procedure for Quantitative Determination of Lead in Sugars by Inductively Coupled-Plasma—Atomic-Emission Spectrometry (ICP-AES)

Abstract

A sample-preparation procedure for the determination of lead in sugars by inductively coupled-plasma—atomic-emission spectrometry was developed and validated using glucose and sucrose as examples. The characteristic detection wavelength and sugar decomposition conditions were selected. The suitability was assessed using a validation protocol for specificity, calibration curve linearity, limits of detection and quantitation, accuracy, precision, and intralaboratory precision.
