Spectroflux Analytical Fluxes for Analytical Techniques - Alfa Aesar

Introduction

The analysis of refractory materials can be reduced to a simple, accurate procedure with the use of Spectroflux analytical fluxes.

Refractory materials such as ores, slags and minerals are often very resistant to acid attack, making the preparation of a sample solution difficult and time consuming. Selection of an effective method of disintegrating the sample matrix to a reproducible form is a prerequisite for speedy, precise and accurate analysis. Flux fusion is such a method.

Fusion with a molten alkali metal borate flux provides a rapid and simple means of dissolving chemically stable materials to yield glass-like solid solutions. This method eliminates any inhomogeneity of particle size, density or composition in the sample.

Samples of a wide variety of materials may thus be prepared in a simple manner for analysis by instrumental or chemical techniques.

Analytical Techniques

Spectroflux® analytical fluxes can be used in conjunction with the following:

  • Direct reading optical or X-ray fluorescence (XRF) spectrometers
  • Atomic absorption (AA) spectrometers
  • Inductively Coupled Plasma Emission Spectroscopy (ICP) techniques
  • Spectrophotometers
  • Polarographs
  • Ion selective electrodes
  • Classical analytical techniques.

Whichever method is chosen, Spectroflux® analytical fluxes offer the analyst the benefits of speed and analytical precision.
