Advanced Compositional Analysis Makes It Easier and Faster to Identify Unknown Material
New York, Apr 28th, 2019 – Matexcel, as a leading service provider in materials science, offering a full range of materials covering polymers, metals, ceramics and natural materials, in addition to professional consultation service in manufacturing and characterization, recently announces its launch of Compositional Analysis service to help researchers identify unknown material, and understand the structure-property relationships for each component.
In materials science, component analysis is a valuable tool to better understand the structure-property relationships for each component and their synergistic behaviors to characterize significant changes in the material structure and elemental distribution. In Matexcel, researchers can obtain information about the presence of an element or chemical group, the number or concentration of elements, as well as the position of each element present at sub-nanometer resolution through analyzing a given sample. The analysis process can be performed through one or more complementary techniques depending on the sample type.
Mass spectroscopy
Mass spectrometry, as an analytical technique that ionizes chemicals and classifies ions based on their mass-to-charge ratio, an atom or molecule in a sample can be identified by correlating a known mass (eg, the entire molecule) with the identified mass or by a characteristic fragmentation mode. Normally, Mass spectrometry is always used in conjunction with other instruments. For example, different ionization tools such as electron ionization (EI), matrix-assisted laser desorption/ionization (MALDI), and inductively coupled plasma (ICP) are used.
X-Ray Fluorescence
It can be used to directly analyze solid samples, thin metal films, petroleum products and a variety of other materials. An X-ray tube is used to illuminate the sample with the main X-ray beam. Some of the impinging primary X-rays are absorbed by electrons in the innermost electron shell of the atom. This causes excitation and ejection of the absorbed electrons, which is called photoluminescence.
Vibrational spectroscopy
It consists of three main tools: Fourier Transform Infrared (FTIR), Near-Infrared (NIR), and Raman spectroscopy. FTIR is used to study functional groups of solid or liquid materials using the discrete energy levels for vibrations of atoms in these groups.
Nuclear magnetic resonance (NMR)
Nuclear magnetic resonance spectroscopy is an analytical chemistry technique used for quality control and research to determine the content and purity of a material and its molecular structure. At present, NMR has been widely used to quantitatively analyze mixtures containing known compounds.
