- The common elements analyzed by XRF
- Why it is important to track these elements
Some instruments, like the Thermo Scientific ARL
QUANT'X EDXRF spectrometer, can perform
analysis in 4 minutes or less. Typical runs include
the analysis of 40 elements.
XRF can easily analyze F to U (fluorine to
americium) in solids, liquids, powders and
depositions, while high-powered instruments can
measure below F.
Energy dispersive XRF requires little to no sample
prep, making it the most popular method for
analysis of particulate matter collected on air
filters.
Features such as elemental mapping analysis can
enhance the capabilities of an XRF system by
providing additional screening, contamination
identification and inclusion analysis.
SOIL ANALYSIS
The ability to accurately analyze trace elements in
geological samples depends upon an XRF’s
sensitivity, resolution and background/overlap
correction function. Typical analysis of rocks and
soil involves the identification of up to 35
elements. Let’s take a look at the common
elements analyzed by the Thermo Scientific ARL
PERFORM’X spectrometer in varying rock
samples.
Geological samples are formed by constant deposits
of inorganic and organic materials over millions of
years.
As layer of deposit accumulates upon layer, the
weight creates pressure and increased temperature
creating rocks or other formations.
Over time, these formations are eroded and carried
away by rain, wind and snow and deposited in
streams and lake beds.
Analysis of these materials is of importance as it
gives not only indications of the mineral bodies
present, but also environmental contaminates.
ITALIANO
La spettrometria a fluorescenza a raggi X (XRF) è
il metodo preferito per l'analisi dell'aria e del
suolo. Per il monitoraggio dell'aria, la
combinazione di sensibilità superiore ed analisi
non distruttiva di XRF è ideale per la misurazione
di elementi specifici nel particolato
ambientale. Nel frattempo, nell'analisi del suolo, la
capacità di XRF di identificare un'ampia gamma di
elementi a concentrazioni dinamiche lo rende
adatto per l'analisi di campioni geologici.
