Binders
For the preparation of pressed pellets for XRF, in most cases, a binder is required.
FLUXANA binders in x-ray fluorescence analysis (XRF):
BOREOX, a direct replacement for boric acid
This is a harmless organic material which shows excellent binding properties and high stability under x-rays. It is particularly good when used as a backing material.
CEREOX
Can be used alternatively. CEREOX is comprised of a wax, previously known as Hoechstwax. This material is clean and very stable under x-rays. Mixed with a sample CEREOX forms a perfect pellet with any material.
CELLEOX is a cellulose based binder
Mostly used as grinding aid. A particular property is the adsorption of liquids so it can be used, mixed with aggressive liquids, for analysis in a sample cup.
MULTIMIX is a grinding aid
Harder than CELLEOX and especially good for hard sample materials such as cement or sand. Typically, 2 to 3 0.25 gram tablets would be added to 30 grams of sample in the mill.
Sample and binder must be mixed homogeneously
FLUXANA recommends their automatic mixer MU-K-Mixer
Fluxes
Borate flux with guaranteed purity from own production. All fluxes are delivered with a certificate of analysis. Anhydrous homogeneous pre-fused fluxes with a low loss on ignition and defined granulometry. With these fluxes the sample will be disolved totally in a borate glass with a perfect surface.
