EDX-7000/8100 - Options

Screening Analysis Kits

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.

Internal Calibration Curves and Automatic Calibration Curve Selection

Internal calibration curves
Internal calibration curves are provided for many materials, making it unnecessary to provide a large number of standard samples.

Automatic calibration curve selection
The software automatically selects the best calibration curve for the material, freeing the user from the need to select analysis conditions.
As an incorrect calibration curve selection can result in large error in the quantitation results, this function contributes to improved data reliability.

Shape correction
The fluorescent X-ray and scattered X-ray intensities are compared for each element (BG internal standard method) to eliminate the effects of the sample shape and thickness in the quantitation values.

Threshold Values
A threshold value can be set for each material and element. The screening evaluation method changes according to how the threshold values are set.

Evaluation Character String
Character strings can be set for display in the analysis results when the threshold value is not exceeded, in the gray zone, and when the threshold value is exceeded.

Report Template
Set the report style from among the templates supplied as standard.

Three screening Analysis kits are available to suit different applications.

RoHS Screening Analysis Kit
Kit for screening cadmium, lead, mercury, chromium, and bromine. Polyethylene samples containing these five elements are supplied in the kit for instrument management.

Small Spot Analysis Kit for EDX-8100

For Analysis of Small Contaminants and Defect Analysis in Small Regions

Minimum 0.3 mm X-Ray Irradiation Diameter Effective for the Analysis of Small Contaminants and Small Regions

Features

• 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 component 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 not only the brass, but the "free cutting brass" contains Lead.

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

Also Capable of Film Thickness Measurements for Small Spots of Plating

When film thickness measurements are performed with the calibration curve method or the thin-film FP method, the sample (measurement position) must be larger than the X-ray irradiation diameter. This system supports film thickness measurements for small spots of plating, which were difficult at an irradiation diameter of 1 mm.
