Positive Material Identification (PMI) / Chemical Analysis

CDJ specializes in onsite PMI for alloy verification per your specification or end customer specifications using the latest and most recognized instrumentation in x-ray fluorescence (XRF) or optical emission spectrometer (OES) technologies.

Full chemical analysis, including light elements such as Carbon, can be performed using optical emission spectrometer (OES) for precise material grade identification or re-establish material traceability.



Non-Destructive Testing / Material Evaluations

PMI and chemical analysis testing can be performed in a totally non-destructive or semi-non-destructive manner. We also offer Liquid Penetrant examination (LP), Magnetic Particle examination (MP), Ferrite testing and various hardness testing capabilities to further evaluate material physical properties.


Laboratory Metallurgical Testing

CDJ offers full laboratory chemical analysis capabilities utilizing stationary OES and combustion/fusion C, S, N, and O determination along with destructive mechanical testing, metallography and micro hardness testing.
