We have the sophistication to detect very low level concentrations of Ionic Contamination by Ion Chromatography (IC). Our state-of-the-art test equipment can detect and identify parts per million (ppm) contaminants in air, water, or industrial products such as printed circuit boards. Specific ion identification includes such anions as Nitrates, Nitrites, Bromides, Chlorides, Phosphates, Fluorides and Sulfates, as well as such cations as ammonium, Ca, Li, Mg, K and Na.

Our Fourier Transform Infrared (FTIR) Spectrometer is used to identify contaminants of organic, non-metallic materials including plastics, pure liquids, and minerals such as silicates. The FTIR is also equipped with a microscope, which can identify micro-contaminants using either the attenuated total relfection (ATR) method or the external reflection method.
