for XRF analysis of liquids

Why sample preparation?
One of the many benefits of X-ray fluorescence (XRF)
spectrometry is that it requires very simple preparationof samples. However, keep in mind that XRF delivers themost accurate and reliable measurements when you pay
close attention to sample preparation.
That being said, why are we preparing samples?
1.	To get the material in the correct form to fit into thespectrometer.
2.	To minimize particle size effect, mineralogical effect,and surface roughness.
Most liquids can be analyzed without further treatments.
Simply use a specially developed plastic cup with aprotective foil that acts as an X-ray transparent window.
From oils and fuels to water or concentrated acidsolutions, there’s always a safe and practical way ofanalyzing liquid samples by XRF.

Liquid sample cups
Malvern Panalytical offers dedicated and single
use sample cups in 32 or 40 mm diameter, withcorresponding lids. These cups are carefully designed

with high standards in production control. They aresafe to use and ensure that will get the best analyticalconditions for any liquid (or loose powder) samples.

Foils
Choosing the best foil for a specific application
guarantees the integrity of the cup and spectrometer aswell as good analytical results. Factors such as chemical
resistance to the samples (polymer composition),presence of low-level contaminants, thickness(robustness versus transmittance) and presentation form
(convenience of use) all play an important role in theselection process.

Non-assembled or pre-assembled cups
Usually, cups are provided as separate plastic parts thatyou can easily assemble before use with the chosen
foil. Alternatively, Malvern Panalytical also offer readyto-use cups with different foil options. This may be aninteresting alternative if you want to avoid any hassle
with cup assemblage.
