ICP-MS (Inductively Couple Plasma - Mass Spectrometry) provides analysis of metals down to the parts per billion level for solutions and the parts per million level on solid samples. Our standard turnaround is 3-5 days depending on the sample and analysis needed.
ICP-AES analysis (Inductively Coupled Plasma - Atomic Emission Spectroscopy) provides analysis of metals down to trace levels. We can provide trace element analysis results as low as 50 ppm depending on your material, sample size and elements requested. ICP analysis can work with smaller samples due to the fact acid digestion is required. Our standard turnaround is 3-5 days depending on the complexity of the digestion needed to put the sample into solution.
OES Analysis (Optical Emission Spectroscopy) provides analysis of metals down to trace levels and is less destructive than an ICP analysis. While it requires prepping the flat surface with some grinding to ensure a clean burn, it leaves the sample relatively intact in case further analysis is needed.
This service is preferable if you have a larger sample size because it is less expensive than a digestion method such as ICP-AES. The ideal sample is 1" x 1" flat surface, but depending on the material and elements needed, smaller samples can be accomodated. Standard turnaround is 3 days or less.
SEM-EDS or SEM-EDX
SEM-EDS Analysis (Scanning Electron Microscopy - Energy Dispersive Spectroscopy) is particularly useful with a very small sample such as in a failure analysis where you may only have debris or shavings. While some light elements cannot be detected, our team can often give you a statement that the sample is or is not consistent for the elements checked with a desired specification.
Wavelength-Dispersive X-Ray Fluorescence Spectroscopy (WD-XRF) offers compositional analysis of various metals. The method requires a solid sample able to cover a 29mm diameter opening; however, smaller samples can be accommodated. Note that some light elements (such as boron, beryllium, etc) cannot be detected via this method.
Like OES this method is fast, somewhat less expensive than ICP, and is relatively non-destructive. We currently offer this service from our Ithaca, NY lab on stainless steel, copper, nickel, titanium and cobalt alloys. Standard turnaround is 3 days or less.
