Fast, versatile elemental screening using the Revontium XRF spectrometer with Omnian quantitation software

This application note shows that the compact Revontium XRF spectrometer can be used with Omnian software to achieve rapid and straightforward quantitation of a variety of sample types, with default settings yielding reliable results after only 4 min measurement time per sample.

Introduction

Omnian is a software package from Malvern Panalytical that enables reliable quantitation of XRF samples to be achieved when dedicated methods or certified standards do not exist. Developed for the top-of-the-range Epsilon and Zetium spectrometers, Omnian is also applicable to Revontium, Malvern Panalytical’s compact energy-dispersive XRF spectrometer.

As well as the software package that is the foundation of Omnian, initial instrument calibration uses a set of 18 standards. Calibration using these standards can be done in the factory or on-site using Malvern Panalytical’s own copies of these standards, with Omnian subsequently being maintained using a single dedicated monitoring sample. Alternatively, the whole set of Omnian standards can be purchased, and the instrument calibrated on-site by a Malvern Panalytical specialist. During analysis, Omnian’s advanced Fundamental Parameters algorithm automatically deals with the analytical challenges posed by samples of widely different compositions, enabling it to provide accurate results in a remarkably short time-frame.
