EDX-7200 - Options

Ideal for RoHS, ELV, and Halogen Screening

The optional screening analysis kits allow even beginners to start RoHS, halogen, or antimony screening analysis right from the day of purchase.
Simply mount the sample, select the analysis conditions, enter the sample name, and wait for the results. The analysis results are displayed with a pass/fail evaluation after just a few minutes. RoHS extended elements (P, Cl, Sn, Sb) are also supported by the optional RoHS enhanced screening kits, and ease of use has been improved with a more accurate threshold evaluation.

Automatic Measurement Time Reduction

• This 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.
  
  By improving the count rate, the screening accuracy has been improved with the same measurement time as conventional equipment. In addition, the software reduces the time that was unconditionally measured until the time set in the gray zone.

Three screening analysis kits are available to suit different applications.

EDXIR-Analysis software is specially designed to perform qualitative analysis using data acquired by an energy dispersive X-ray (EDX) fluorescence spectrometer and a Fourier transform infrared (FTIR) spectrophotometer.

This software is used to perform an integrated analysis of data from FTIR, which is excellent at the identification and qualification of organic compounds, and from EDX, which is excellent at the elementary analysis of metals, inorganic compounds and other content. It then pursues identification results and the degree of matching. It can also be used to perform EDX or FTIR data analysis on its own.

The library used for data analysis (containing 485 data as standard) is original to Shimadzu, and was created through cooperation with water supply agencies and food manufacturers. Additional data can be registered to the library, as can image files and document files in PDF format. It is also effective for the linked storage of various types of data as electronic files.

Integrated Analysis of Contaminant Data and Data Comparisons for Confirmation Tests

 To perform qualitative analysis automatically, simply click “Analyze Both Data” and select the EDX/FTIR data^*1. This heightens the efficiency of data analysis and provides strong support for contaminant analysis.

In addition to a list of hits, the integrated data analysis results show EDX profiles and FTIR spectra found as hits from the library. If the user wishes to browse the respective data analysis results, they can be checked by clicking "Single".

In addition, with the data comparison function, which calculates the degree of matching between the actual measured data and the data registered in the library, the software can be used for countermeasures against "silent change"^*2 and for other confirmation tests. Clicking the “Print” button prints the results in a fixed format and also saves them in Word format^*3.

• Using the EDX profile, data are classified as inorganic, organic, and mixture. Integrated data analysis is performed by applying priority levels to each classification. (Patent pending)
• A term used in Japan to indicate changes to materials by suppliers without the knowledge of the manufacturers.
• Microsoft^® Word must first be installed.

The examples here show an integrated analysis of black rubber contaminant data acquired and a data comparison for a polyvinyl chloride (PVC) examination object and the standard product. From the integrated data analysis results, it is evident that the black rubber contaminant is acrylonitrile-butadiene rubber (NBR), which contains calcium carbonate and zinc stearate. In addition, from the data comparison, the degree of matching between the PVC examination object and the standard product is 0.8506. Lead (Pb) and acrylic were detected from the EDX and FTIR data, but were not detected in the standard product. Accordingly, it is surmised that the examination object contains components different to those in the standard product.

Data Browsing and the Registration, Editing, Deletion of Data, Images, Document Files

By clicking "Edit" and selecting an existing library, the data, images and documents registered in the selected library can be browsed. Data can be registered, edited, deleted. A new library can also be created.

In addition, if data for a sample were acquired by instruments other than EDX and FTIR instruments (such as a chromatograph, mass spectrometer, or surface observation system), it can be converted into PDF format and then registered, enabling linked storage to the EDX/FTIR data.

Measure the Samples Kept in the Holder with EDX and FTIR
The Holder Can Be Used as the Sample Stocker after the Measurement

Enables More Efficient Analyses

This foldable holder consists of an adhesive layer with samples attached and polypropylene film designed for a fluorescence X-ray. When using EDX for measurement, close the holder and place the polypropylene film directly to the irradiation side (downside). When using FTIR for measurement, open the holder and press the samples attached to the adhesive layer against the ATR prism. This enables the replacement of samples, at a minimum, saving on labor and making analysis more efficient.

Prevents Loss of Samples

Close the holder after the measurement and it can be used as a sample stocker. It is not necessary to transfer the samples to other containers, so there is no danger of losing samples.

For Analysis of Small Contaminants and Defect Analysis in Small Regions

This option can be used to analyze even smaller areas by replacing the collimator plate and sample observation camera. It is especially useful for analyzing trace foreign matter and defects in micro areas, and measuring plating thickness.

Minimum 0.3 mm X-Ray Irradiation Diameter
The excitation X-rays can be collimated to 0.3 mm in diameter, which is effective for the high-accuracy analysis of small contaminants and for defect analysis in small regions, analyses difficult with standard specifications (minimum 1 mm in diameter).

Enlarged Sample Images without Image Quality Degradation
This system supports smaller samples, which heightens the visibility of sample observation images. Users can switch to an enlarged image approximately 2.5 times larger than a previous image, without image quality degradation.

Automatic Four-Stage Switching Between 0.3, 1, 3, and 10 mm in Diameter
The irradiation diameter automatically switches between 0.3, 1, 3, and 10 mm in diameter.
This system supports not only the analysis of small spots but also macro composition analysis at 10 mm in diameter.
Note: The irradiation diameter is the size on the sample surface.

Analysis Example - Small Metal Powder (Approx. 0.1 mm in Diameter) Adhered to the Surface of Snacks

 A small metal powder approximately 0.1 mm in diameter adhered to the commercially available snacks was analyzed with irradiation diameters of 1 mm and 0.3 mm, respectively. At an irradiation diameter of 1 mm, the overall background is significantly increased due to the influence of scattered X-rays from the surrounding area of the metal powder (snacks), resulting in a poor S/N ratio. At an irradiation diameter of 0.3 mm, however, the influence of scattered X-rays from the surrounding area is small, and peak profiles with a good S/N ratio are obtained.

Copper (Cu) and Zinc (Zn) are detected as the major components with both irradiation diameters. It indicates that the metal powder is brass regardless of the irradiation diameter used. However, at 0.3 mm in diameter, the peak of Lead (Pb) is also identified, which suggests that the metal powder is “free cutting brass”.

By using an irradiation diameter of 0.3 mm, more accurate analyses can be performed, even for small contaminants on substances such as organic materials that strongly scatter X-rays.
