Extremely Flexible

Accommodates all types of samples from small to large, from powders to liquids. Options include a vacuum measurement unit,
helium purge unit for highly sensitive measurement of light elements, and a 12-sample turret for automated continuous measurements.

Sample Observation Camera and Collimators
Automatic collimator switching in four stages: 1, 3, 5, and 10 mm diameter
Select the irradiation chamber from four values to suit the sample
size.
Select the most appropriate irradiation diameter for the sample
shape: 1 mm diameter for trace foreign matter analysis or defect
analysis; 3 mm or 5 mm diameter for small sample volumes.

Sample observation camera included as standard
Use the sample observation camera to confirm the X-ray irradiation
area on a specific position.

Automatic Replacement of Five Primary Filters

Primary filters enhance detection sensitivity by reducing the Filter Effective Energy (keV) Target Elements (Examples)
continuous X-rays and the characteristic X-rays from the X-ray tube. #1 15 ~ 26 ZrKa, MoKa, RuKa, RhKa, CdKa, SnKa
They are useful for the analysis of trace elements. #2 2 ~ 5 ClKa, CrKa
The EDX-7200 incorporates five primary filters (six, including the open #3 5 ~ 7 CrKa

Effect of the Primary Filters

Freely Combine Collimators and Primary Filters
The collimators and primary filters are driven independently and can be combined to address specific requirements. Select the optimal
combination from 24 (6 filters x 4 collimators) available options.
Quantitative analysis using the FP method is possible with all combinations.
