Contamination Testing Lab

Microstructure of Sample Material

Applied Technical Services’ contamination testing lab serves clients by determining whether the chemical purity of their product’s component materials has been compromised in any way by contaminating agents. Our team of chemists accomplishes this by using a variety of methods, selecting the one most appropriate for each sample material. Whether clients need contamination testing for material qualification or failure analysis purposes, ATS is well-equipped to serve their needs.

Our Methods of Analysis

The chemists who staff our contamination testing lab are very experienced in identifying a wide variety of contamination occurring from plant production lines or processes. Our Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectrometer (FTIR) are key tools in solving contamination issues. Inductively Coupled Plasma (ICP) and Ion Chromatography (IC) are also useful tools in determining the elemental makeup of a sample. Our main focus in contamination testing is to identify the contaminant and to help you determine where it is coming from so that you can eliminate it.

Fourier Transform Infrared Spectroscopy (FTIR)
The FTIR is used to identify organic materials such as polymers, adhesives, organic residues and lubricants. We have over 60,000 spectra in our spectral libraries for comparing unknown spectra. We have two FTIR spectrometers in house including a micro-FTIR with a built in microscope useful in analyzing organic thin films, surface contamination, fibers or composites.
Scanning Electron Microscopy (SEM)

Our Hitachi S-3700N scanning electron microscope (SEM) is outfitted with a light element Oxford/Link energy dispersive spectrometer (EDS). The SEM boasts a very generous depth of field with a magnification range of 5 to 200,000X. Through the use of the SEM/EDS techniques, we can determine the elements present in the contaminant.
