Extract

Many manufacturing processes in the chemical industry require frequent monitoring of the composition of the product. Ideally, an analysis of this type should be simple to carry out, rapid, reliable, and not require a seperate analytical laboratory. Energy Dispersive X-Ray Fluorescence (EDXRF), due to its relative simplicity of instrumentation, speed of analysis, and non-destructive nature, is well suited to on-line applications, when used in conjunction with a flow cell.

A question that is frequently raised in this type of analysis is: How do the precision and accuracy of these measurements compare with measurements made upon the same solution in sample cups (static). The purpose of this study was to compare the precision and accuracy of on-line with static analyses of the same types of solutions.
