Chemical Analysis

You can get answers to your questions when you need them the most. We will provide you with accurate chemical analysis delivered in a timely manner at competitive prices.


Analyses are performed by skilled personnel with combined experience of over 70 years. Our analytical instrumentation is programmed for the majority of engineering alloys used in modern manufacturing. There are five main techniques used to provide chemical analysis at Anderson Laboratories. Below are the techniques used to determine the composition of your materials:

  • Optical Emission Spectroscopy - Inductively Coupled Plasma (OES-ICP) is used for chemical analysis of non-standard material grades or samples with irregular geometries.
  • Direct Reading Spectrometer - Optical Emission Spectroscopy (OES) is used for the majority of the samples that are analyzed in our laboratory. Metallic samples over ⅛” thick and at least ⅝” in diameter can be analyzed using this technique.
  • Optical Emission Spectroscopy - Glow Discharge Spectroscopy (OES-GDS) is used for analysis of irons (gray, ductile, malleable, ni-resist, white types, etc.). Its versatility enables it to be used for common grades of steels and higher alloyed materials as required for specific determinations.OES-GDS (Optical Emission Spectroscopy Glow Discharge Spectroscopy) utilized for all classifications of irons (Grey, Ductile, Malleable, Ni-resist, White types, etc.). Its versatility enables it to be used for common grades of steels and higher alloyed materials as required for specific determinations.
  • Combustion and inert gas fusion techniques are used to determine Carbon, Sulfur, Nitrogen, and Oxygen by means of the most current LECO® instrumentation.
  • Scanning Electron Microscopy - Energy Dispersive Spectroscopy (SEM/EDS) is a system capable of single elemental mapping, particle sizing, and contamination layer identification. The large stage of our system facilitates the examination of larger samples – ideal for fracture analysis and failure evaluations.
