Its applicable for all spectroscopy,
higher is the substance higher is the intensity of light emit or absorbed. Taking some known amount and calculating the intensity ,finally ploting a graph of them . Then for our unknown we can measure intensity and extrapolating graph we can know the amount quantitatively
Don't be confuse with intensity and frequency of light. Intensity says about the amount and frequency about energy.
In chemistry, analysis refers to the process of examining a substance to determine its composition, structure, and properties. This can involve techniques such as spectroscopy, chromatography, and mass spectrometry to identify the chemical components present in a sample. Analysis plays a crucial role in determining the purity of substances, understanding their reactivity, and characterizing their behavior.
UV spectroscopy and IR spectroscopy are both analytical techniques used to study the interaction of light with molecules. UV spectroscopy measures the absorption of ultraviolet light by molecules, providing information about electronic transitions and the presence of certain functional groups. On the other hand, IR spectroscopy measures the absorption of infrared light by molecules, providing information about the vibrational modes of the molecules and the presence of specific chemical bonds. In terms of applications, UV spectroscopy is commonly used in the study of organic compounds and in the pharmaceutical industry, while IR spectroscopy is widely used in the identification of unknown compounds and in the analysis of complex mixtures.
One can obtain structural information from NMR spectroscopy by analyzing the chemical shifts, coupling constants, and peak intensities of the signals in the NMR spectrum. These parameters provide insights into the connectivity, stereochemistry, and environment of atoms in a molecule, allowing for the determination of its structure.
NMR noise can interfere with the signals being measured in nuclear magnetic resonance spectroscopy, leading to inaccuracies in the data. This can result in errors in the determination of chemical structures and other important information obtained from NMR spectra.
In nuclear magnetic resonance (NMR) spectroscopy, chemical shift is significant because it provides information about the chemical environment of atoms in a molecule. It helps identify different types of atoms and their connectivity, aiding in the determination of molecular structure.
The most common methods used for the determination of protein structure are X-ray crystallography or NMR spectroscopy.

The goal is the determination of the qualitative and quantitative composition of materials.
TC ,or total serum cholesterol, is a quantitative analysis of cholesterol in the patients blood. The type of cholesterol is as important as the quantity of cholesterol.

Qualitative analysis means just to detect the presence of a substance in the sample while quantitative analysis is the determination of that substance i.e., in which amount it is present in the sample.
It can be used for element identification and can used in Atomic spectroscopy and can be used to help "atoms with low ionization potentials become ionized."
Any kind of graph can be used for quantitative data.
Determination is used when you need to achieve a goal.
X-ray spectroscopy is used for detecting of breakable bone in body(2)it also for internal structures
Spectroscopic methods: such as UV-Vis spectroscopy, IR spectroscopy, and NMR spectroscopy, which analyze the interaction of matter with electromagnetic radiation. Chromatographic methods: such as gas chromatography and liquid chromatography, which separate and analyze components of a mixture based on their interactions with a stationary phase and a mobile phase. Mass spectrometry: a technique that ionizes molecules and separates them based on their mass-to-charge ratio, providing information about the molecular weight and structure of compounds. Titration: a method of quantitative chemical analysis used to determine the concentration of an unknown solution by reacting it with a solution of known concentration. Electrochemical methods: such as voltammetry and potentiometry, which measure electrical properties of chemical systems to provide information on redox reactions and ion concentrations.
The purpose of stellar spectroscopy is to determine the chemical composition of stars, the temperature and some other characteristcs..
