Unrivaled Analytical Performance

The high-performance SDD detector and optimized hardware achieve a high level of sensitivity, analysis speed, and energy resolution that were previously unattainable. The EDX-8000/8100 system also permits detection from 6C.

High Sensitivity − Lower Limit of Detection Improved 1.5 to 5 Times! −

The high-performance SDD detector and combination of optimized optics and primary filters achieve previously unheard-of high levels of sensitivity. The sensitivity is higher than the previous Si (Li) semiconductor detector across the entire range from light to heavy elements.

High Speed − Throughput Increased by up to a Factor of 10 −

The high fluorescent X-ray count per unit time (high count rate) of the SDD detector permits highly precise analysis in a shorter measurement time. This feature is achieved to the maximum when analyzing samples that generate a lot of fluorescent X-rays, such as samples with a metal as the Main component element.

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 standard

Use the sample observation camera to confirm the X-ray irradiation position on a specific position to measure small samples, samples comprising multiple areas, or when using a Micro X-Cell.

Automatic Replacement of Five Primary Filters

Primary filters enhance detection sensitivity by reducing the continuous X-rays and the characteristic X-rays from the X-ray tube. They are useful for the analysis of trace elements.
The EDX-7000/8000/8100 incorporates five primary filters as standard (six, including the open position), which can be automatically changed using the software.

Filter Effective Energy (keV) Target Elements (Examples)
#1  15 to 24  Zr, Mo, Ru, Rh, Cd
#2  2 to 5  Cl, Cr
#3  5 to 7  Cr
#4  5 to 13  Hg, Pb, Br
#5  21 to 24(5 to 13)*  Cd (Hg, Pb, Br)

* This filter also cuts the background in the energy range shown in parentheses ( ).

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.

Optional Vacuum Measurement Unit and Helium Purge Unit

Sensitivity for light elements can be increased by removing atmosphere. Two options are available: a vacuum measurement unit and a helium purge unit.
The helium purge unit is effective when measuring liquid samples and samples that generate a gas and cannot be measured in a vacuum.

Comprehensive Quantitation Functions

Calibration Curve Method

A standard sample is measured and the relationship with the fluorescent X-ray intensity plotted as a calibration curve, which is used for the quantitation of unknown samples.
Although this method requires selection of a standard sample close to the unknown sample and creation of a calibration curve for each element, it achieves a high level of analysis accuracy.
This method supports all types of corrections for coexistent elements, including absorption/excitation correction and correction for overlapping elements.

Fundamental Parameter (FP) Method

This method uses theoretical intensity calculations to determine the composition from the measured intensities. It's a powerful tool for the quantitative analysis of unknown samples in cases where preparation of a standard sample is difficult. (JP No. 03921872, DE No. 60042990. 3-08, GB No. 1054254, US No. 6314158)

Automatic Balance Setting Function (Patent pending)
A balance setting is required to use the FP method on principal components such as C, H, and O. The software automatically sets the balance if it determines from the profile shape that a balance setting is required.

Film FP Method

The instrument also offers the thin-film FP method function. The film FP method permits the film thickness measurement of multilayer films, and simultaneous film thickness measurements and quantitative film composition.
When using the film FP method, the substrate material, deposition sequence, and element information can be set.

Background FP Method

The background FP method adds scattered X-ray (background) calculations to the conventional FP method, which only calculates the fluorescent X-ray peak intensity (net peak intensity).
(Patent pending: Japanese Patent No. 5975181)
This method is effective at improving quantitation accuracy for small quantities of organic samples, film thickness measurements of irregular-shaped plated samples, and film thickness measurements of organic films.

Matching Function

Matching Results

The matching function compares analysis data for a sample with an existing data library and displays the results in descending degree of confidence.
The library contains content data and intensity data and the user can register each type. The content data values can be entered manually.

Functions to Enhance Usability

Easy Instrument Startup

PCEDX Navi offers instrument initialization and startup (X-ray startup) with simple mouse-click operations.
After instrument startup, the stabilization function operates for 15 minutes. Analysis and instrument checks are disabled during this period, ensuring that all users collect data in a stable instrument environment.

Automatic X-ray Tube Aging

When an X-ray tube has not been used for a long period, it requires aging before it can be used again. The software automatically performs the appropriate aging according to the period of non-use.

Condition Password Protection

The software offers password protection. Condition settings and changes can only be made by a person who enters the password.

Incorporates General Analysis Software

EDX-7000/8000/8100 incorporates PCEDX Pro software that has more flexibility functions. This software offers analysis, conditions settings, and data processing using familiar operations. It also allows loading of data profiles and quantitation values acquired with a previous Shimadzu EDX series instrument.
