Rapid and Cost-efficient TXRF - an Alternative to ICP

The S4 T-STAR® is a versatile tool for the analysis of a broad range of sample types including suspensions, powders, nanoparticles or films. This puts it ahead of ICP, which requires fully dissolved liquid samples.

  • The  TXRF spectrometer S4 T-STAR® offers lowest detection limits in the sub-ppb range.
  •  TXRF offers lowest operation costs and does not require, gases, media or sophisticated lab infrastructures.
  • The automatic quality control feature provides confidence in data and instrument quality.
  • The system is optimized for 24/7 operation in industrial routine analysis.
  • Bruker's wide selection of sample trays and tools accelerates sample preparation and minimizes errors and contamination risks.

Analytical Challenges in Pharma, Medical and Environmental Research?

  • The S4 T-STAR® provides a powerful solution for water, effluent, air and soil analysis for the recovery of a healthy environment; for example, environmental monitoring by direct measurement of contaminants in wastewater, slurries and effluents in the low ppb range.
  • The TXRF spectrometer accelerates biomedical research for tomorrow’s healthy society. New insights into the development of cancer, Alzheimer’s disease or dementia are based on a deeper knowledge of the function of essential and toxic metals.
  • The S4 T-STAR® measures catalyzer elements in pharmaceutical research according to the values given by US and EU Pharmacopeia guidelines; for example, detection of sub-ppm catalyzer elements in active pharmaceutical ingredients (API) and additives. 
  • TXRF is a powerful technology for food fraud prevention in globalized supply chains; for example, food safety according to FAO/WHO standards.

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.
