Powerful Package for Sample Prep to XRF Analysis

Aug 11 2017 Comments 0

Retsch, a leading solution provider for sample homogenisation and characterisation, has added a new pellet press to its product range. The PP 35 is a compact benchtop model which uses a maximum pressure force of 35 tons to produce smooth and stable pellets suitable for XRF analysis.

Before the sample can be pressed to a pellet, it needs to be ground to a homogeneous fineness below 100 microns. The MM 400 mixer mill is ideally suited for homogenising up to 8 x 30 ml sample material quickly and reproducibly. If the sample needs to be mixed with a binding agent for stability, this can be done in conical centrifuge tubes which are clamped into a special adapter.
 

For the homogenisation of larger volumes of hard and brittle sample materials, Retsch offers two models of Vibratory Disc Mills, RS 200 and RS 300 XL. These achieve grind sizes below 100 microns within seconds and are therefore highly suitable for pulverising samples for pelletising. Pellet presses with 25 t and 40 t maximum pressure force complete Retsch’s offering for quick and reproducible preparation of XRF samples.

To ensure accurate and reproducible XRF analysis results, the sample needs to have a uniform particle size distribution and the pellet needs to be as dense as possible. Both requirements are easily met when using Retsch’s powerful package for sample preparation to XRF analysis.
