TXRF Spectrometers

Sub-ppb Limits of detection: Analysis of smallest sample amounts in the nanogram or microgram range

Cl, As, Se Simultaneous multi-element trace analysis: Easy quantification of critical elements forming volatile compounds

Green No gases, no cooling media: Carbon footprint far lower than ICP

 

The S2 PICOFOX - Smart, Green, Compact

The S2 PICOFOX is a transportable TXRF spectrometer for ultra-trace element analysis. Due to its complete independence of any gas or cooling medium, the analyzer can be used not only in the laboratory but also for on-site analyses in the field.

• Simultaneous multi-element trace analysis, including halogenides
• Analysis of smallest sample amounts in the nanogram or microgram range
• Simple quantification using an internal standard without daily calibration
• Suitable for various sample types and applications
• No matrix or memory effects
• Low operating cost, no need for any media, disposables or periodic maintenance 

 

Advantages of TXRF Compared to EDXRF Spectrometers

The S2 PICOFOX working principle is based on total reflection X-ray fluorescence (TXRF) analysis. The use of monochromatic radiation and total reflection optics leads to the following benefits of the S2 PICOFOX:

• Reduced absorption and scattering effects in the sample matrix enable an easy quantification by internal standardization.
• Short detector to sample distance leads to an enhanced fluorescence yield.
• Due to the reduced background, detection limits are several orders of magnitude lower.
• Extremely low sample amounts of liquids and powders can be precisely quantified.
