Laboratory Sample Preparation

Solutions that make sense

Why is High Quality Sample Preparation so Important ?


Sample preparation is one of the single greatest sources of error in quantitative analysis but often receives the least amount of attention.   Modern analytical instruments including X-ray Fluorescence(XRF), X-ray Diffraction (XRD) and Inductively Coupled Plasma( ICP) are capable making incredibly precise measurements, but the results are only as good as the sample presented to the instrument that makes the measurement.  This makes it easy to obtain exactly the wrong results.

This is why high quality sample preparation is so critical in a laboratory environment.

High quality sample preparation requires attention to detail through a number of often repetitive and tedious tasks including grinding, sample weighing and dosing, pressing, fusion, dissolution and cleaning of the apparatus for the next sample.  This provides many opportunities to introduce error into an analysis before it is ever made

 The FLSmidth products are designed to automate all of tedious and labor intensive tasks associated with preparing pressed pellets to insure high quality analyses sample after sample. 



Sample Preparation for X-ray Analysis


FLSmidth provides a number of automated sample preparation systems for preparing samples for quantitative analysis for XRD and XRF.  These complete solutions can be used as standalone systems or incorporated into a fully automated laboratory providing cost effective solutions that can grow with your laboratory needs. 


 X-ray Diffraction(XRD)

   ASP 100 Soft Press for XRD analysis                                                  

ASP 100 Soft Press for  rapidly preparing samples for XRD analysis. Incorporates patented technology to dramicly reduce errors caused by sample height dispacecment and preferred orientation.





X-ray Fluorescence(XRF)



Centaurus Mill and Press for XRF Analysis


Centaurus  is a fully automatic Combined mill and press that produces pressed powder pellets from granular materials such as raw meal, clinker, cement, ore, slag and mine exploration samples for XRF analysis.









DCF Fusion instrument for XRF fused beads


The DCF 820/830 is a completely automated instrument for preparing fused beads for analysis by XRF. Designed to improve sample to sample reproducibility, increase sample throughput, and lower the cost per analysis by fully automating the repetitive labor intensive tasks involved in the preparation of fused beads.

Pulverising Mills and Jaw Crushers

Our pulverising mills have been the cornerstone of the assaying industry for 20 years and are used extensively on mine sites, exploration camps and in commercial and research laboratories around the world. We pioneered large capacity fine pulverising using our unique bowl and disc grinding elements.

These mills and bowl systems are complimented by our comprehensive range of jaw crushers
