How does TXRF work?

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.

Accessories to Help Avoid Contamination during TXRF Sample Preparation

When detecting samples at ultra-low ppb limits contamination avoidance is of the highest priority – when working with a pure sample the key to this is excellent sample preparation.

Bruker provides a range of accessories alongside their S2 PICOFOX and S4 T-STAR systems.

These include a T-BOX to help achieve contamination-free and accurate sample pipetting and the T-DRY for the vacuum desiccation of samples; with both being designed to help users avoid making any contact with the sample carrier.

Following the collection of measurements, the sample disks can be efficiently and effectively cleaned for later use using Bruker’s chemically resistant washing cassette before clean storage in the T-BOX.
