ICP-OES and ICP-MS Analysis for 2D Materials
Recently, two-dimensional (2D) materials have found numerous applications in various scientific fields such as multiphase catalysis, gas storage, and environmental remediation. Accurate characterization of the purity of 2D materials is critical to their application results. Inductively coupled plasma emission spectrometry (ICP-OES) and mass spectrometry (ICP-MS) are fast, accurate, and non-destructive techniques that have been used for decades to detect trace contaminants in samples, respectively.
Alfa Chemistry offers ICP-OES and ICP-MS testing to analyze the composition and trace impurities in 2D materials such as graphene, which are critical to understanding their properties. Contact us today so we can help you with your 2D material testing!
Why ICP-OES / MS
ICP Analysis has low detection limits for chemical determinations, making it a useful tool for quality control applications, contamination analysis, etc.
ICP-OES: Also known as ICP-AES (atomic emission spectrometry), it is a flame technique for the determination of trace elements in prepared samples. Argon gas flowing through the ICP torch is ignited and ionized in an electromagnetic field, where a high-temperature plasma of approximately 7000 K is generated. Properly prepared samples are continuously drawn into this inductively coupled argon plasma discharge. The elements of interest reach the excited state and emit energy in the form of light when they return to the ground state with the wavelength characteristics of each particular element. The intensity of the light emission is measured at each specific wavelength and compared to the intensity of the previously measured concentration of the known element.

ICP-MS: It uses a flame technique in which prepared samples are continuously drawn into an inductively coupled argon plasma discharge and ionized at high temperatures. Once converted to ions, they are brought into the mass spectrometer, where they are focused by an electrostatic lens, where they are separated by their mass-to-charge ratio, which allows ICP-MS to provide isotopic information for each element of interest.
