As rules regulating the release of effluent into the environment become more stringent, the tools used to ensure treated effluent complies with those rules must also evolve to meet the demand. Shimadzu Scientific Instruments recently introduced the

EDX-7200 energy dispersive X-ray fluorescence spectrometer that was designed to support new regulations and directives for consumer and environmental compliance.

Designed for fast, accurate detection and analysis of elements in various lab samples, the EDX-7200 is equipped with a high-resolution silicon drift detector to achieve a higher count rate and detection efficiency than its predecessor models. In addition, a high-speed circuit achieves highly precise analysis of the target in a shorter measurement time. In fact, it increases the count rate by up to 30 times compared to Shimadzu’s former model, the EDX-720. Improved algorithms and performance also help to reduce measurement times. 

This flexible instrument accommodates all types of samples — from small to large, from solids to powders to liquids. That means that not only can it be used in the environmental analysis of effluent, it can also be used on soil, combustion ash, filters and fine particulate matter. To measure a liquid sample, the user simply adds it to a sample cell with film on the bottom. This method makes the unit effective for the detection and quantitation of additive components and worn metals in aqueous solutions, organic solvents or oils.

A new automatic measurement time reduction function automatically switches to the next analysis channel if a controlled substance clearly has a high or low concentration, making evaluation possible while measurement is underway. This achieves more efficient screening analysis.

Four-stage automatic collimator switching capability enables the user to select the irradiation chamber from four values to suit the sample size: 1, 3, 5 and 10 mm diameters. The included sample observation camera is used to confirm the X-ray irradiation area on a specific position. Three optional screening analysis kits are available — an RoHS, halogen and antimony screening analysis kit; a phosphorus screening analysis kit; and a tin screening analysis kit.

It is compatible with Shimadzu’s PCEDX Navi software, which simplifies X-ray fluorescence spectrometry for beginners, while providing the feature set and capabilities demanded by more experienced users. The user interface offers intuitive operation and provides a convenient operating environment for users regardless of expertise level.
