MASS SPECTROGRAPHY Meaning and
Definition
-
Mass spectrography is a scientific technique used to determine the mass-to-charge ratio of ions present in a given sample. It is a powerful analytical tool used in various fields including physics, chemistry, biochemistry, and environmental science. The device used to perform mass spectrography is called a mass spectrometer.
The process of mass spectrography involves several steps. First, the sample is ionized using various methods such as electron impact or chemical ionization. This converts the analyte molecules into ions. The ions are then accelerated through an electric field and separated based on their mass-to-charge ratio using magnetic fields. The separated ions are detected and their signals are converted into a mass spectrum, which is a graphical representation showing the relative abundance of ions at each mass-to-charge ratio.
Mass spectrography enables identification and quantification of compounds present in a sample based on their molecular masses. It provides valuable information about the elemental composition, structure, and purity of a substance. Additionally, mass spectrography is often used to elucidate the fragmentation pattern of molecules, allowing for structural analysis and identification of unknown compounds.
The applications of mass spectrography are vast. It is used in forensic analysis, drug discovery, environmental monitoring, food safety testing, and proteomics research, among others. The high sensitivity, accuracy, and versatility of mass spectrography make it an indispensable tool in modern scientific research and analysis.

Etymology of MASS SPECTROGRAPHY
The word "mass spectrography" is derived from two main components: "mass" and "spectrography".
The term "mass" refers to the measure of the property of matter that represents the amount of substance in an object. It comes from the Latin word "massa", meaning "lump" or "mass".
"Spectrography" is a combination of two words: "spectro" and "graphy". "Spectro" is derived from the Latin word "spectrum", meaning "appearance" or "image". "Graphy" is derived from the Greek word "graphē", which means "writing" or "drawing".
When combined, "spectrography" refers to the study or technique of producing images or recordings of a spectrum.
