INDUCTIVELY COUPLED PLASMA/MASS SPECTROMETRY (ICP-MS)
TRACE ELEMENTAL ANALYSIS of ALUMINUM, IRON-BASED, NickeL, Cobalt, Copper, and Titanium Alloys, POLYMERS AND PLASTICS
Inductively Coupled Plasma / Mass Spectrometry is a very sensitive elemental analysis technique that provides very low detection limits for most elements present in a sample. Samples need to be in solution form, which requires solid samples to be dissolved. Test specimens are digested with a combination of acids appropriate for the chemical composition of the alloy. Certified reference materials that are also NIST traceable are digested in the same manner as the samples being analyzed and are utilized to validate the calibration curves and instrument operation when available.
The instrument is calibrated per use, using calibration standards manufactured by laboratory personnel. The calibration standards are matrix matched (Ni, Fe, Ti, etc.) to the samples being analyzed. Elements to be analyzed are added to calibration standards using NIST traceable solution standards. Calibration curves usually consist of 3-6 calibration standards.
The samples and references are brought up to a known volume and diluted as necessary to quantify the trace elements of interest. The samples are then run on appropriate matrix curves. An ICP-MS can quantify a wide array of elements in many different matrices. The ICP-MS utilizes a mass/charge ratio to detect the ions in a sample based on each elements’ known isotopic mass(es).
