Find Out How TXRF Works

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.

S4 T-STAR - New Standards in TXRF Benchtop Spectrometry

NEW! S4 T-STAR - GIXRF Option: Advanced Materials Characterization

The GIXRF Option for the S4 T-STAR allows users to undertake advanced materials characterization via GIXRF (Grazing Incidence X-Ray Fluoresence). GIXRF is particulary suited for the analysis of nanoparticles, monolayers and systems with stratified layers. Find out more by downloading the flyer.

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.

What is your Analytical Challenge for TXRF?

Environmental monitoring

Contaminants in water

Without the need for any gases, media or a sophisticated lab infractructure with hoods and exhausts, the S4 T-STAR can be easily installed at any production site where wastewaters have to be monitored.

Biomedical research

Metal analysis in tissues, blood, urine and other body fluids

Trace elements (or: metals) are increasingly used as dietary supplements in the prevention of widespread diseases and as clinically effective adjuvant therapeutics, and have become a popular research area in basic and applied sciences. These trace elements confer unique reactivities to their respective enzymes.

Pharma and Biopharma

Catalyzer analysis in Pharma

Detection of metal contamination or monitoring of catalyzer elements in pharmaceutical production according to the new EU and US Pharmacopeia 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.
