COMPARISON OF ULTRA LAMP FLAME ATOMIC ABSORPTION AND ICPOES MEASUREMENT SYSTEMS FOR THE DETERMINATION OF PRECIOUS METALS IN AUTOCATALYST SAMPLES

摘要

A study was completed comparing the analysis of precious metals in a wide variety of automobile catalyst materials using Flame Atomic Absorption equipped with the Varian Ultra lamp system to Inductively Coupled Plasma Optical Emission. Ultra lamps are high intensity discharge lamps, which can be used instead of conventional hollow cathode lamps. The study has shown that the Ultra Lamp system provides superior quality precious metal analytical data on automobile catalyst materials. The study has also indicated a much wider application of the Ultra Lamp system in our laboratory.
