Bruker S4 T-STAR
Bruker Micro-TXRF

The Bruker S4 T-STAR is a powerful ultra trace element analysis system. TXRF (Total Reflection X-ray Fluorescence) spectroscopy is an established technique for trace element analysis in a wide variety of samples. The S4 T-STAR simplifies TXRF, with 24/7 routine operation and guaranteed data quality, making it an attractive alternative to ICP.


Lowest detection limits

In the sub-ppb range.

Variety of sample types

Wide range of sample carriers available. High capacity for up to 90 samples.

Automatic quality control routines

Fast and cost-effective alternative to ICP

Much simpler sample preparation and more eco-friendly, with a CO2 footprint around 10 times lower.


  • Low sub-ppb detection limits
  • Flexible and versatile – analyse a wide variety of samples
  • Automatic quality control features
  • 24/7 operation for overnight industrial routine analysis
  • Multi-user operation and 90 sample capacity
  • Selection of tools for fast sample preparation, minimising errors and contamination

Cost-Effective Alternative to ICP

TXRF is a fast and cost-effective alternative to ICP analysis. Where ICP requires fully dissolved liquid samples, the S4 TStar can analyse a wide variety of sample types. Various carriers and tools are available for different samples, making preparation easier and quicker than ICP. It’s also much greener, with a CO2 footprint around 10 times lower.

Environmental monitoring

Environmental Monitoring

Maintain a healthy environment by monitoring contaminants in water, effluent, air and soil. < 10 ppb detection of contaminants in wastewater, slurries and effluent.



Automatic QC Procedures

The Bruker S4 TStar is the first TXRF spectrometer that runs QC routines automatically to qualify operation and performance in the background, ensuring data quality. Automatic stability and sensitivity checks are run with integrated QA samples.

Minimise Sample Contamination

Bruker’s SampleCare™ protects samples and improves data quality. Reduced air flow and integrated sample housing minimises the risk of contamination. A slight stream of nitrogen shields the samples, and removes argon from the air for improved detection of palladium and silver.

Convenient Sample Control and Archiving

Control the quality of your sample with a magnified image from a CCD camera. All sample images are archived automatically for review.

High Capacity

The S4 TStar sample changer has a high capacity of up to 90 sample discs. Automated batch processing is available, so you can measure samples overnight. The TStar is designed for multi-user operation, with up to 10 different trays. These can be loaded and unloaded while the instrument is running.

Easyload™ Sample Station

Dedicated sample trays are available for different types of samples. These are recognised automatically, for efficiency and to prevent errors. All open measurement jobs can be started immediately, increasing throughput and speed.

Final Results on the Spot

Typically, samples are prepared multiple times. Straight after measurement, statistical data  is reported automatically (average, standard deviation etc.). Standard libraries allow the determination of recoveries. Any deviations from the admissible tolerance are highlighted for you.
