Chemical Testing:


When quick results are needed, spectrographic analysis by APL Inc. is the answer. Both speed and repeatable accuracy are gained through the use of a computer-controlled, direct reading, optically emitting, vacuum spectrometer. The spectrometer will perform its analysis on the majority of the solid samples submitted, and is programmed to cover virtually all of the standard engineering alloys. A computer-generated data file of all elements requiring ASTM standards is retained for future reference.


Carbon, Sulfur, Hydrogen, Nitrogen and Oxygen Analysis:

Traditional spectrographic techniques for the determination of carbon, sulfur, nitrogen, and oxygen can be inherently inaccurate. Thanks to the use of LECO ® analyzers, APL can determine the concentrations of these elements in a sample with an exceptionally high degree of accuracy.


EDS and XRF Analysis:

The techniques of Energy Dispersive Spectroscopy (EDS), applied in conjunction with a Scanning Electron Microscope (SEM), are used in determining data on a range of valuable parameters:

  • Mode and origin of failures
  • Corrosive element determination
  • Microscopic chemistry
  • Microscopic defect
  • Surface analysis
  • Particle analysis.

Corrosion products, inclusions, and other very small but important constituents of castings and forgings are identified through use of the SEM/EDS combination.


Slag and other various Ferro-Alloys can be analyzed using our XRF analyzer.  This instrument provides us with a high degree of accuracy and precision when determining these materials - something that a spectrometer cannot do.  When it comes to analyzing unknown materials, the XRF can provide us with semi-quantitative results which leads us and the customer in the right direction for identificaiton and replication.


We would be happy to provide you with more details about our company and what we can do for you. Contact us at 800 236-3909 800 236-3909 or use our contact form.
