Introduction to Chromatography: Definition and Importance

Chromatography is a powerful analytical technique that plays a critical role in the separation, identification, and quantification of chemical compounds in various mixtures. Defined as a method by which components of a mixture are distributed between two phases—a stationary phase and a mobile phase—chromatography has been widely adopted across numerous fields, including chemistry, biology, environmental science, and medicine.

Introduction to Capillary Electrophoresis: Definition and Importance

Capillary Electrophoresis (CE) is a powerful analytical technique that leverages the principles of electrophoresis to effectuate the separation of ionic species based on their charge-to-mass ratio. In essence, CE utilizes a narrow capillary tube filled with an electrolyte solution to separate analytes; when an electric field is applied, charged particles migrate through the medium, allowing for their separation in a matter of seconds to minutes.

Introduction to Size Exclusion Chromatography (SEC)

Size Exclusion Chromatography (SEC), also known as gel filtration or gel permeation chromatography, is a powerful analytical technique primarily employed for the separation of biomolecules, polymers, and other macromolecules based on their size.

Introduction to Ion Chromatography

Ion chromatography (IC) is an analytical technique widely employed for the separation and quantification of ionic species in various matrices. This method has gained prominence due to its capability to analyze both cations and anions with high sensitivity and specificity. Unlike traditional chromatographic techniques that focus on neutral molecules, ion chromatography focuses on charged particles, making it particularly useful in diverse fields such as environmental monitoring, pharmaceuticals, and food safety.

Introduction to Affinity Chromatography

Affinity chromatography is a powerful and selective technique widely utilized in the field of analytical chemistry, particularly for the purification and separation of biomolecules, such as proteins and nucleic acids. The fundamental principle of this method is based on the specific interactions between a target molecule and a ligand that is immobilized on a solid support. This technique operates through the exploitation of natural affinities, making it incredibly useful for isolating biomolecules with high specificity.

Introduction to Supercritical Fluid Chromatography (SFC)

Supercritical Fluid Chromatography (SFC) is a sophisticated analytical technique that combines the principles of chromatography with the unique properties of supercritical fluids. It is primarily used for the separation, identification, and quantification of a broad range of compounds, making it an invaluable tool in various fields including pharmaceuticals, environmental testing, and food science.

Introduction to Flash Column Chromatography

Flash Column Chromatography (FCC) is a widely accepted technique in the realm of analytical chemistry, particularly known for its efficiency and speed in the separation of complex mixtures. This method leverages the principles of traditional column chromatography while enhancing the process through the application of elevated pressure, which significantly improves the elution of compounds.

Introduction to Paper Chromatography

Paper chromatography is a widely utilized analytical technique that enables the separation and identification of complex mixtures. At its core, this method leverages differences in the partitioning behavior of substances between a stationary phase, typically a type of paper, and a mobile phase, usually a solvent. The simplicity and versatility of paper chromatography have made it an invaluable tool in various fields, ranging from biochemistry to environmental analysis.

This method is grounded in several fundamental principles:

Introduction to Thin-Layer Chromatography (TLC)

Thin-layer chromatography (TLC) is a powerful and versatile analytical technique employed for separating and identifying compounds in a mixture. It gained popularity due to its simplicity, rapid execution, and cost-effectiveness, making it an invaluable tool in various fields like pharmaceuticals, food safety, and environmental monitoring.
