Monitoring of Wastewaters, Effluents and Mining Outfalls

How Bruker’s advanced analytical techniques meet the challenge of changing regulations.

Monitoring of toxic elements in wastewaters and effluents according to governmental regulations is getting more important. Total reflections X-ray fluorescence (TXRF) analysis is a rapid and cost-efficient analytical method without need for sophisticated lab infrastructure.

International decrees strictly regulate the discharge of sewage. Testing for heavy metals is sewage by conventional methods, such as ICP, requires complete digestion of the sample using hazardous chemicals. This time-consuming and destructive sample preparation step can be omitted when using a TXRF spectrometer. Untreated sewage can be diluted with a detergent solution and measured immediately after the addition of an internal standard.

Key elements (e.g. chromium, arsenic, lead) are detectable far below usual threshold values. The simple sample preparation leads to quick results and allows immeadiate, continuous monitoring of sewage treatment.

The S2 PICOFOX is the world's first transportable TXRF spectrometer with detection limits for many elements in the lower pg or ppb range. Due to its compact design it can be used onsite for rapid screening.

The TXRF spectrometer S4 T-STAR offers lowest detection limits for all elements from magnesium to uranium. Samples can be analyzed after a rapid preparation and the element composition is quantified without time-consuming daily calibrations. Automatic quality control procedures guarantee highest data quality during 24/7 operation.

Both TXRF spectrometers are compact plug and play systems without need for gases, media or advanced lab infrastructure. Operation costs are negligible and basic user skills are sufficient.
