Sigma Ultra Pure X-Ray Fluxes

• offer a simple method of sample solution preparation for coarse refractory materials such as iron ore, slags and other materials which are often very resistant to acid attack.
• offer an effective method of disintegrating the sample matrix to a reproducible form, this is an essential prerequisite for accurate analysis.
• are produced from Ultra Pure Grade quality raw materials (these specifications exceed analytical reagent grade quality).
• have been manufactured in Australia for more than 25 years to many different formulations thereby ensuring almost immediate delivery.
• are being used by Mining, Industrial and Governmental X-Ray Analytical Laboratries with complete success.
• Sigma X-Ray Alkali Metal Borate Fluxes provide an effective and simple means of dissolving chemically stable materials to give glass-like solid solutions. This method ensures homogeneity of particle size density and composition in the sample.

Sigma Ultra Pure X-Ray Fluxes offer many benefits including:

1. Low fusion losses
2. Controlled particle size
3. High bulk density for more economical use of platinum crucibles
4. Homogeneity including the availability of internal standards and/or lanthanum oxide
5. Low concentration of rock forming impurities

Apart from fluxes, Sigma Chemicals stocks all chemical X-Ray requirements and we sincerely invite your inquiries.
