Multi-modal techniques mean more from one measurement
Historically, if an analysis required information about the chemical and structural qualities of a material, sequential measurements would be necessary; one measurement for chemical data and another for structural data. However, this sequential data failed to show the true correlation among these qualities, providing poor conclusions and results.
Multi-modal techniques allow the user to see how changes in one material quality affect other material qualities, thereby eliminating the guesswork that comes from sequential measurements.
Thermo Fisher Scientific offers solutions that help enable materials scientists and engineers to innovate at a faster pace, produce more reliable and better performing materials and processes, reduce costs, and shorten the time to discoveries. Explore how multi-modal techniques can replace sequential measurements.

Raman spectroscopy
Raman spectroscopy is an analytical technique that observes vibrational, rotational, and other low-frequency modes in a system through inelastic scattering of monochromatic light, usually from a laser. This interaction shifts the energy of the laser photons, revealing information about molecular vibrations. It is valuable for characterizing molecular structures, identifying substances, and studying molecular interactions without extensive sample preparation.
FTIR spectroscopy
FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample. The usefulness of infrared spectroscopy arises because different chemical structures (molecules) produce different spectral fingerprints
X-Ray photoelectron spectroscopy (XPS)
X-ray photoelectron spectroscopy, also known as electron spectroscopy for chemical analysis (ESCA), is a highly surface-sensitive, quantitative, chemical analysis technique that can be used to solve a wide range of materials problems. XPS is the measurement of photoelectrons ejected from the surface of a material that has been irradiated with X-rays. The kinetic energy of the emitted photoelectrons is measured. This energy is directly related to the photoelectrons’ binding energy within the parent atom and is characteristic of the element and its chemical state.
Compounding & extrusion, rheology
Compounding & extrusion and rheology are essential in industrial ceramics and glass manufacturing. Compounding involves mixing raw materials to create a homogeneous mixture, while extrusion shapes this mixture into desired forms. Rheology studies the flow behavior of these materials, helping optimize processes like mixing and molding, and ensuring quality control. Together, these techniques are used to analyze the material and help ensure efficient production and high-quality, consistent products.
