Description: Specific heat is a fundamental property of a substance representing the amount of heat energy required to raise the temperature of a unit mass of the substance by one degree Celsius (or one Kelvin). It is expressed in units of energy per unit mass per degree (J/kg°C or J/kgK). Principles: Applications: Strengths: Limitations: In …
Description: Residual stress analysis involves measuring the internal stresses that remain in a material after the removal of external loads or thermal gradients. These stresses can exist in materials without any external forces being applied and may affect the material’s structural integrity, dimensional stability, and performance. Principles: Applications: Strengths: Limitations: In summary, residual stress analysis …
Description: Chemical speciation analysis involves the identification and quantification of different chemical forms or species of an element in a sample. It’s founded on principles from analytical chemistry and involves various techniques aimed at separating, detecting, and characterizing distinct chemical forms of elements within a matrix. Principles: Applications: Strengths: Limitations: In summary, chemical speciation analysis …
Description: Raman Spectroscopy is an analytical technique used to study molecular vibrations in materials by measuring the scattering of light when it interacts with a sample. It provides information about molecular structure, chemical composition, and bonding within a sample based on the vibrational modes of its constituent molecules. Principle: In Raman Spectroscopy, a laser beam …
Small Angle X-ray Scattering (SAXS) is an analytical technique used to study the nano- and mesoscale structures of materials by analyzing the scattering patterns resulting from X-rays interacting with a sample. SAXS provides information about the size, shape, and arrangement of particles or macromolecules in a sample. Principle: When an X-ray beam passes through a …
Resonance Ionization Mass Spectrometry (RIMS) is an advanced analytical technique that combines resonance ionization spectroscopy with mass spectrometry to analyze and detect trace elements and isotopes with exceptional sensitivity and selectivity. It’s particularly powerful for ultratrace analysis and for studying nuclear and atomic properties of elements. Principle: RIMS operates by using multiple laser beams with …
Description: Optical Emission Spectroscopy (OES), also known as atomic emission spectroscopy, is an analytical technique that analyzes the optical emission spectra of elements to identify and quantify their presence in a sample. It involves exciting atoms in a sample to emit characteristic wavelengths of light, which are then analyzed to determine the elemental composition and …
Description: Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique used to study the molecular structure, dynamics, and composition of organic and inorganic compounds. It exploits the magnetic properties of certain atomic nuclei within a magnetic field to provide detailed information about the chemical environment of atoms in a molecule. Principle: NMR works on …
Description: Neutron Activation Analysis (NAA) is an analytical technique used for identifying and quantifying trace elements in a wide variety of materials. It involves irradiating a sample with neutrons, which induces the formation of radioactive isotopes. The emitted gamma rays from these activated isotopes are then measured to determine the elemental composition and concentration of …
Description: LECO (short for Laboratory Equipment Corporation) combustion analysis refers to a method of determining the elemental composition of organic and inorganic materials, specifically for hydrogen (H), carbon (C), nitrogen (N), oxygen (O), and sulfur (S). It involves the combustion of a sample at high temperatures, followed by the detection and quantification of the resulting …
