MASS CHROMATOGRAPHY Meaning and
Definition
-
Mass Chromatography is a technique used in analytical chemistry that involves separating mixtures of compounds based on their mass-to-charge ratio. It is a powerful tool in both qualitative and quantitative analysis, allowing the identification and quantification of individual components within a sample.
The process of Mass Chromatography begins by injecting a sample into a chromatographic column, which contains a stationary phase. The sample components are then separated as they move through the column, based on their interactions with the stationary phase. This separation is achieved by a combination of adsorption, partition, and other physical and chemical interactions.
As the separated components exit the column, they enter a mass spectrometer where they are ionized and brought to a high vacuum. The ions produced are accelerated, separated, and detected based on their mass-to-charge ratio, allowing for their identification and quantification.
Mass Chromatography is widely used in various fields, including environmental analysis, pharmaceutical development, forensic science, and food and beverage industry. It offers high sensitivity and selectivity, allowing for the detection and quantification of compounds at low concentrations.
The advancements in Mass Chromatography technology have led to the development of various techniques such as gas chromatography-mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS), and high-performance liquid chromatography-mass spectrometry (HPLC-MS). These techniques have revolutionized the field of analytical chemistry by providing accurate and precise measurements, improving efficiency, and expanding the scope of analysis.

Etymology of MASS CHROMATOGRAPHY
The word "chromatography" is derived from the Greek words "chroma", meaning "color", and "graphy", meaning "writing" or "description". This reflects the original purpose of chromatography, which was to separate and describe different colored components in mixtures.
The term "mass chromatography" combines the word "chromatography" with "mass", referring to the mass spectrometry technique that is often used in conjunction with chromatography. Mass spectrometry is the analytical technique used to measure the mass-to-charge ratio of ions, enabling the identification and quantification of molecules in a sample.
Therefore, "mass chromatography" signifies the combination of chromatography and mass spectrometry for the separation, identification, and quantification of components in a mixture.
