We are proud to announce the launch of the Claisse LeDoser-12 automatic dispensing balance.
This 12-position instrument is the latest of a series of cutting-edge products used for sample preparation by fusion for XRF and ICP analysis.
Its three weighing modes (sample-to-flux ratio, catch weight and absolute weight) fulfill all needs in the laboratory.

Saves a tremendous amount of labor time related to the weighing task
LeDoser-12 gives a breath of fresh air in the sample preparation process. In fact, weighing samples and dispensing borate flux has always been known to be a very …

Claisse® LeNeo was launched in 2014. It’s a one-position instrument that is used in various types of industries.
Read the following lines to discover why it’s the right instrument to use in universities and colleges’ labs.
Reason 1 – Safety
The safety of students should always be an academic institution’s main concern. Manual fusion is often used in colleges and universities’ laboratories, but it involves the manipulation of hot vessels and is not representative of technologies used in the labor market. By being fully automatic, LeNeo instrument guarantees cold-to-cold operation and avoids the …

When performed correctly, fusion is the sample preparation technique that leads to the obtention of the most precise and accurate XRF and ICP analytical results. Among all factors that need to be considered to get great glass disks or solutions and therefore excellent analysis, the choice of flux is one of the most important.
Let’s discover why.
An Indispensable Chemical
The flux forms the matrix of the disk analyzed by the spectrometer. It must melt before the sample dissolves into it. An adequate flux allows to:

Optimize the solubility of the sample and …

What is fusion?
You might already know that the choice of the sample preparation method for X-Ray Fluorescence (XRF) or Inductively Coupled Plasma (ICP) atomic emission spectroscopy analysis is critical to obtain precise and accurate results with the spectrometer.
Have you ever heard about fusion? Let’s demystify this technique and have a look at its benefits when compared to pressed pellets.
What is it exactly?
Fusion for XRF analysis consists of mixing a ground sample with a borate flux (lithium or sodium) inside a 95% platinum / 5% gold crucible, heating around 1000 °C with …
