New S2 PICOFOX Benchtop TXRF System

The S2 PICOFOX is the new portable benchtop total reflection X-ray fluorescence (TXRF) analyser to quantify elemental concentrations from 0.1 ppb to % level. TXRF previously was limited to floor standing units or bulky lab systems with emphasis to the semiconductor and coatings metrology. TXRF does not require time-consuming digestion by hazardous chemicals. In contrast to AAS/ICP instrumentation the S2 PICOFOX is suitable for almost all sample types like liquids, suspensions, filters,
particles and body fluids.
The S2 PICOFOX was made for the analytical laboratory and field use thus enabling TXRF performance for clinical, nutritional, environmental applications for the first time Making use of Bruker`s award winning XFLASH® detector technology the system is equipped with a 30mm2 XFLASH®
detector with superb energy resolution and resolution stability at
count rates of 100 000 cps.
Operating without any external gasses, water-cooling or any other media the system can detect elements from Al-U and quantify them down to ppb levels. Sample amounts can be in the nano gram range with the ability to analyse solid samples directly.
Early adopter customer application studies show the versatility of the uses of the S2 PICOFOX in the fields of pharma authenticity, environmental testing, food, agricultural products, nutritional supplements, biochemical and medical applications.
The successful applications range from R&D, such as Nano materials, blood, plasma and protein analysis to Forensics and Pharmaceutical
product verification.
As a complementary tool to ICP-MS in a commercial laboratory setting the S2 PICOFOX is being among others thoroughly evaluated by FLORA Research Laboratories, Washington USA:
“WE LOVE IT! Doors have opened in so many areas that we just did not consider in the past because of the relative ease and speed of sample
analysis. When it is so easy to prepare samples for analysis and you can do many elements, it makes one more likely to approach inorganic
tasks that would not normally be utilised.” says Mr. Neal Kababick, Director of Flora Research.
Successful applications studies with clients from the mining sector enable the S2 PICOFOX to be used as well for geochemical screening,
optimisation of ore processing, and exploration.
Both manual and auto sampler models of our benchtop TXRF S2 PICOFOX can be equipped with different excitation sources (Mo and W) to optimise the analytical performance.
Unlike traditional WDXRF or EDXRF, TXRF does not suffer from matrix effects requiring dedicated calibrations for each material. All S2
PICOFOX instruments are pre calibrated from the factory in Berlin, Germany and traceable to primary standards.
Bruker AXS assists their clients not only with the instrument, but also by providing assistance and know how on sampling, applications and
method validation.
The S2 PICOFOX is directly supported through our centres in The Woodlands Texas and Madison Wisconsin by a team of experienced
application scientists and engineers. The S2 PICOFOX is also part of the technology offering by Bruker Analytical Services (Woodlands, Texas)
as a gateway to study new technologies and applications to enhance our clients` capabilities.
