This integrated EDX-FTIR analysis software (EDXIR-Analysis) is designed to perform a qualitative

analysis of data obtained by FTIR analysis (suited to identi cation and characterization of organic
materials) and EDX analysis (suited to elemental analysis such as of metals and inorganic materials) to
identify target materials and calculate degrees of similarity against reference data. EDXIR-Analysis can
also perform an analysis of data from EDX analysis alone or FTIR analysis alone. The spectral library
used by EDXIR-Analysis is an original Shimadzu library (485 data sets included as standard) created
with help from water utility companies and food producers. New data, images, and PDF format
document les can also be added to the library, offering an effective means of linking together and
storing different types of data electronically.

˙ Integrated Analysis of Contaminant Data and Identification Testing by Data Comparison
An analyst simply clicks on “Analysis Using Both EDX and FTIR Data,” selects the EDX and FTIR data, and the EDXIR-Analysis software automatically
performs the qualitative analysis . The software streamlines a time-consuming process that is typically performed by the analyst, offering a powerful tool

All Data is Linked Together in the Library
An example integrated analysis was performed on data collected from a black rubber-like contaminant and, in a separate analysis, data collected from a
legitimate product made of polyvinyl chloride (PVC) was compared with data collected from a product for inspection.
The integrated analysis showed the black rubber-like contaminant was acrylonitrile butadiene rubber (NBR) with calcium carbonate and zinc stearate.
The data comparison showed the degree of similarity between the PVC product for inspection and the legitimate PVC product was 0.8506. According to
Products for EDX and FTIR Systems
the EDX pro le and FTIR spectrum, lead (Pb) and acrylic not present in the legitimate product were detected in the product for inspection. Based on this
nding, the components not present in the legitimate product are probably contaminants in the product for inspection. EDXIR-Holder Contaminant Retainer/Storage Container (Optional)

Samples placed in an EDXIR-Holder can be analyzed on both an EDX system and an FTIR system. After analysis, the sample can also be stored in the
EDXIR-Holder with no further processing.

˙ Reducing Analytical Work
EDX EDX Pro le FTIR Spectrum Plastic Analyzer IRXross+AIMsight
The EDXIR-Holder contains an adhesive lm for sample adhesion and a polypropylene lm for X-ray uorescence analysis and can be opened and closed.
To perform EDX analysis, the EDXIR-Holder is closed and positioned with the polypropylene lm facing the irradiated side in an EDX system (facing down).
To perform FTIR analysis, the EDXIR-Holder is opened and the sample adhered to the adhesive lm is pushed directly against the ATR prism. EDXIR-Holder

minimizes the work involved in sample preparation, thus reducing analytical tasks and streamlining the analysis process.

˙ Preventing Lost Samples
Integrated Analysis Data Comparison
After analysis, the EDXIR-Holder can be closed and the sample stored inside the EDXIR-Holder with no further processing. The sample does not need to be
transferred to a separate storage container, thus lowering the risk of sample loss.
