Elemental Analysis by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) (CAT#: STEM-EA-0208-ZJF)

Introduction

Based on ICP-OES, we provide detection of lithium (atomic number 3) through uranium (atomic number 92), except gases, halogens, and low levels of phosphorous and sulfur, with typical detection limits of parts per billion in solution.<br />With ICP-OES, we determine the bulk elemental composition of a wide variety of sample types, including powders, solids, liquids, and suspensions. The sample size requirement is 250 mg to 1 gram of solid sample; typical solution volumes are between 2 and 10 mL.<br />Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) is another ICP technique that uses a similar sample introduction system as ICP-MS. Argon plasma is used to atomize and ionize the sample, as with ICP-MS. A spectrum with a typical range of 165 - 800 nm is viewed and measured, either sequentially or simultaneously, in ICP-OES. The detection limits of ICP-OES systems are typically two to three orders of magnitude higher than those of ICP-MS systems. It is, however, necessary to use ICP-OES when identifying and quantifying certain lighter elements (e.g., S, Ca, Fe, K, and Se) that suffer considerable interferences with ICP-MS. In addition, manufacturers of ICP-MS instruments have eliminated negative ion capabilities in order to reduce manufacturing costs. Consequently, the only viable atomic spectroscopy method for Cl, Br, and I is ICP-OES.<br />If you have any requirements or questions. Don't hesitate to contact us.
