Electric Fusion Fluxers

Katanax®, a brand of SPEX SamplePrep, is the pioneer in electrical fusion. The fully automated electric Fluxers are made to prepare glass beads for XRF and solutions for AA and ICP. Exceptional fusion accuracy is combined with all the benefits of electric power, speed, simplicity and robust design for both experienced and novice users.

As a pioneer in electrical fusion, Katanax is still a leader. With the help of the very precise and accurate temperature control, methods are now even being developed with oxidation and/or ashing in the fusion system.

What’s Fusion?

Fusion is a Sample Preparation technique used for analysis with X-Ray Fluorescence (XRF), Inductively Coupled Plasma (ICP) or Atomic Absorbtion (AA).

It is a digestion process in which an oxidized sample is dissolved in molten flux. The most commonly used fluxes are lithium tetraborate and lithium metaborate at a temperature of 1050 ºC. Depending on the type of sample, other fluxes are also used.


The melt is poured into a platinum mould. The resulting glass pearl can be measured immediately.

Examples of applications are: cement, glass, catalysts, ceramics, geology, steel, fertilizer, nuclear, (precious) metals, pharmaceuticals, environment, etc.


The hot borate melt is poured into stirred cups with diluted acid, resulting in a solution that can be measured directly on ICP.

Examples of applications: all oxides, sand, clay and other silica containing samples, catalysts, (precious) metals and alloys, fly ash, polymers, pharmaceuticals etc.
