BORATE FLUXES AND CHEMICALS

Claisse borate fluxes

Your first choice to fuse samples for XRF, ICP and AA analysis

Fusion is a very effective technique to prepare all types of samples for XRF, ICP and AA analysis. It consists of dissolving an oxidized sample in a solvent, usually a lithium borate flux.

As the one-stop shop in fusion and the world leader in the production of fluxes, Claisse develops high-quality chemicals that are easy to use and that ensure no contamination.

When you use the fluxes developed by Claisse, you guarantee the production of homogeneous and stable glass disks by:

  • Avoiding crystallization
  • Reducing the incidence of glass sticking to the platinumware
  • Avoiding cracking

Claisse now offers pre-weighed fluxes to speed up sample preparation. Note that any type or quantity of fluxes can be pre-weighed. Contact your sales representative for more information.

1. Custom Fluxes: A Turnkey Solution Designed for Your Needs

Tired of wasting time preparing your own special flux blends because they are not available on the market? Don't wait any longer, try the custom fluxes offered by Claisse!

Since we are dedicated to always provide the best products and services, we have developed numerous custom fluxes over the years to save you time and to meet your special needs. Our personalized fluxes are homogeneous, they have an outstanding fluidity and they come in any borate ratio. They can be fused directly from the bottle and are made with or without NWA, oxidizer or internal standard.

Claisse develops fluxes with the exact ratio of chemical elements requested by the customer. Here is a list of a few personalized fluxes developed by our experts:

  • Li2B4O7/LiBO2/ LiNO3
  • Li2B4O7 / LiF
  • Li2B4O7/LiBO2/LiBr/NaNO3
  • Li2B4O7/LiBO2/Nb2O5
  • Li2B4O7/LiBO2/LiI/Co2O3

*Some conditions apply. Do not hesitate to contact your Claisse sales representative for more information on our custom fluxes.

2. WHY INVEST IN THE FLUXES DEVELOPED BY CLAISSE?

Claisse® fluxes are manufactured through a unique process that guarantees unmatched purity and outstanding physical properties. Here's why our fluxes are the best on the market:

  • Consistent quality: No need to stock large quantities of flux or to recalibrate your spectrometer after each order. With Claisse, you can always expect the same high-quality flux.
  • Fused and homogeneous: Claisse® borate fluxes consist of homogeneous, spherical and vitreous particles. Each particle has the same composition to avoid segregation and to ensure the analytical accuracy of your analysis. There is no need to recalibrate the instrument every time a new batch of flux is used.
  • 99.98+% pure and 99.995+% ultra pure: Our fluxes are the purest on the market! We guarantee that our pure borate fluxes contain less than 10 ppm for each of the 15 selected elements. The level of contamination for ultra pure fluxes is carefully controlled and analyzed for 30 selected elements. A detailed certificate of analysis is supplied with each order.
  • High density: Claisse borate fluxes are three times denser than the other fluxes on the market. They never fill more than half of the crucible, even when fusions for large 40 mm disks are performed. It eliminates all risks of overflow during agitation.
  • Anhydrous: Claisse fluxes have the lowest water content on the market (< 0.05%).
  • Non-hygroscopic: Our fluxes consist of spherical glassy beads, they are therefore non-hygroscopic. A major problem with absorbed humidity is the loss of accuracy in the analytical results. It is caused by the induced error on the mass of flux weighed, and it affects the sample/flux ratio.
  • Controlled granulometry: Claisse fluxes are 100% less than 500 µm and contain no dust. Consequently, they do not tend to stick to the weighing pan, the funnel and the crucible wall. A controlled granulometry eliminates the segregation effect. It avoids the loss of flux and the formation of glass droplets on the wall of the crucible. It also allows better accuracy.
  • Non-wetting agents (NWAs) integrated: Our fluxes are available with integrated lithium bromide (LiBr) or lithium iodide (LiI). We know that adding an inconstant amount of NWAs to the melt can affect the accuracy of an analysis. You can solve this issue by using our fluxes with integrated NWAs. These fluxes are easier to use and they save you time because you do not have to add the NWAs separately during the fusion process.
  • Outstanding fluidity: Our borate fluxes are therefore easier to handle and weigh.
  • Available from stock: If you are out of stock or have an urgent request, we will promptly ship the product.
