Development and Validation of ICP-MS Method for Lead Determination at PPM Level in Molecular Sieves, Silica Gel and Silica CanisterAuthor(s): Gnanadev*, Ravi Chandra Babu
A robust ICP-MS method was developed for determining the lead content in various packaging materials such as Molecular Sieves, Silica Gel and Silica Canister. The method was developed by using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Sample preparation was done by acid digestion in microwave digestion vessel. The analytical method was validated by measuring several parameters Specificity, Limit of detection (LOD), Limit of quantification (LOQ), Linearity, Precision, and Accuracy. The method was applied satisfactorily for analyzing various molecular sieves, silica gel and silica canister samples.
