Spectroscopy is a scientific technique used to analyze the interaction between matter and electromagnetic radiation to determine the composition, structure, and properties of substances. It is fundamental in fields like chemistry, physics, and astronomy for identifying materials and understanding molecular and atomic interactions.
Chromatography is a laboratory technique for the separation of a mixture into its individual components, based on the differential partitioning between the mobile and Stationary Phases. It is widely used in analytical chemistry for purifying substances and analyzing complex mixtures, such as in pharmaceuticals and environmental testing.
Mass spectrometry is an analytical technique used to measure the mass-to-charge ratio of ions, enabling the identification and quantification of molecules in complex mixtures. It is widely used in fields ranging from chemistry and biology to environmental science and medicine, providing detailed molecular information with high sensitivity and accuracy.
Nuclear Magnetic Resonance (NMR) is a powerful analytical technique used to determine the structure of molecules by observing the magnetic properties of atomic nuclei. It provides detailed information about the molecular structure, dynamics, and environment, making it invaluable in fields like chemistry, biochemistry, and medicine.
Electrochemical analysis involves the study of chemical properties and reactions by measuring the electrical parameters such as current, voltage, and charge. It is widely used in various fields including environmental monitoring, pharmaceuticals, and energy storage to analyze and quantify chemical species and their interactions.
X-ray diffraction is a powerful technique used to determine the atomic and molecular structure of a crystal by measuring the angles and intensities of X-rays scattered by the crystal lattice. This method provides detailed information about the arrangement of atoms within the crystal, which is critical for understanding material properties and designing new materials.
Ultraviolet-visible spectroscopy is an analytical technique used to measure the absorbance of ultraviolet or visible light by a chemical substance, which provides information about the electronic structure and concentration of the substance. It is widely used in chemistry and biochemistry for identifying and quantifying substances, as well as studying chemical kinetics and reaction mechanisms.
Atomic Absorption Spectroscopy (AAS) is an analytical technique used to determine the concentration of metal elements in samples by measuring the absorption of light. It relies on the principle that free atoms in the ground state can absorb light at specific wavelengths, which is directly related to the concentration of the element in the sample.
Gas chromatography is an analytical technique used to separate and analyze compounds that can be vaporized without decomposition. It is widely used in chemistry for the qualitative and quantitative analysis of mixtures, allowing for the identification and quantification of components in complex samples.
Liquid Chromatography is a versatile analytical technique used to separate, identify, and quantify components in a mixture by passing it through a column packed with a stationary phase while a liquid mobile phase moves through it. Its applications span various fields, including pharmaceuticals, environmental testing, and food analysis, due to its ability to handle a wide range of chemical compounds.
Fourier Transform Infrared Spectroscopy (FTIR) is an analytical technique used to identify organic, polymeric, and in some cases, inOrganic Materials by measuring their infrared absorption spectra. It provides rapid and precise measurements of the molecular composition of samples, making it invaluable in both qualitative and quantitative analysis across various fields such as chemistry, biology, and materials science.
Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is an analytical technique used for elemental analysis of samples, capable of detecting metals and several non-metals at concentrations as low as parts per trillion. It combines a high-temperature argon plasma source to ionize the sample with a mass spectrometer to separate and quantify the ions based on their mass-to-charge ratio.
Fluorescence spectroscopy is a powerful analytical technique that measures the intensity of emitted light from a sample after it has absorbed light or other electromagnetic radiation. It is widely used for detecting and quantifying biological molecules, studying molecular interactions, and analyzing the dynamics of complex systems due to its high sensitivity and specificity.
Tenderness evaluation is a critical assessment in various fields, including medicine and food science, to determine the sensitivity or quality of a subject. It involves both subjective and objective methodologies to provide accurate and reliable measurements for diagnosis or quality control purposes.
Concept
An instrument is a tool or device used for a specific purpose, often to facilitate measurement, control, or the creation of art. Instruments can be physical, such as musical instruments or scientific measuring devices, or they can be abstract, like financial instruments used in markets.
An internal standard is a substance added in a constant amount to samples, blanks, and calibration standards in chemical analysis to correct for variability in response due to matrix effects or instrument instability. It serves as a reference to quantify the target analytes accurately, ensuring precision and reliability in analytical measurements.
