About Spectroscopic Analysis

Spectroscopy tests can give information about what chemical compounds and elements are present in a sample, whether certain types of degradation have occurred in a sample, the amount and type of crystallinity  present in the sample, to name a few uses. 

Spectroscopy techniques can be combined with chemical reactions to perform precision, low level analysis of the amount of particular compounds, such as formaldehyde or proteins in a sample.

Spectroscopic analysis can involve radio, microwave, infrared, visible, ultraviolet, x-ray, or even gamma radiation light, and each of these is suited for identifying different properties of the sample being studied.

  • Approaches to Spectrometry

    Inductively Couple Plasma (ICP) is a type of emission spectroscopy that uses the inductively coupled plasma (argon, in our case) to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. The intensity of this emission is indicative of the concentration of the element within the sample. The sensitivity of this technique is quite high, varying by element, from 1ppm to 10ppb.

    Nuclear Magnetic Resonance spectroscopy (NMR) uses radio waves to identify the structures of polymers, copolymers, and other chemical compounds, and can quantify the major components in simple mixtures. 

    Infrared spectroscopy techniques such as Fourier Transform Infrared (FTIR) spectroscopy can identify specific functional groups, polymers, and additives through spectral matching, and certain techniques can test samples by touch in a non-destructive manner.   

    Ultraviolet-visible (UV-Vis) spectroscopy can identify certain organic functional groups, determine whether containers are appropriately light-proof, and perform quantitative analysis of dyes or functionalized compounds of interest.  

    X-ray spectroscopy (XPS) examines arrangements of atomic structures and can determine the amount and type of crystallinity present in a sample.  

    Gamma spectroscopy is used in identification of radioactive elements and for radiometric dating.
