Some of them include column chromatography, thin-layer chromatography (TLC), paper chromatography, gas chromatography, ion exchange chromatography, gel permeation chromatography, high-pressure liquid chromatography, and affinity chromatography [6].
Why chromatography is named so?
The largest molecules of the mixture will travel more slowly while the smallest ones race ahead, causing the stationary phase to develop discrete bands of color corresponding to each component of the mixture. This gives the technique the name “chromatography” or “writing color.”

Waters unveiled a new category of LC technology known as Ultra Performance LC (UPLC) that would take the science of separation to a new level. This liquid chromatography system was the first of its kind, and designed to provide chromatographic run times up to ten times shorter than those of the fastest existing HPLC systems, with up to two times better peak capacity or resolution, and three times better routine sensitivity. For laboratories, these performance characteristics translated into more and higher-quality information per unit of time as well as greater productivity. A particle size of around 1.7 μm as used in UPLC allows greater speed and peak capacity, but also requires the use of a higher pressure to help move the eluent through the column.

How does HPLC work?
Fig.1 shows a basic overview of the HPLC process. The solvent used to separate components in a liquid sample for HPLC analysis is called the mobile phase. The mobile phase is delivered to a separation column, otherwise known as the stationary phase, and then to the detector at a stable flow rate controlled by the solvent delivery pump. A certain amount of sample is injected into the column and the compounds contained in the sample are separated. The compounds separated in the column are detected by a detector downstream of the column and each compound is identified and quantified.
How does a pump work in HPLC?
As for HPLC, the pump delivers the mobile phase at a controlled flow rate (a). Air can easily dissolve in the mobile phase under the standard atmospheric pressure in which we live in. If the mobile phase contains air bubbles and enters the delivery pump, troubles such as flow rate fluctuations and baseline noise/drift may occur. The degassing unit helps prevent this issue by removing air bubbles in the mobile phase (b). After the dissolved air has been removed, the mobile phase is delivered to the column. The sample injector then introduces a standard solution or sample solution into the mobile phase (c). Temperature fluctuations can affect the separation of compounds in the column. The column is placed in a column oven to keep the temperature constant (d). Compounds eluted from the column are detected by a detector which is placed downstream of the column (e). A workstation processes the signal from the detector to obtain a chromatogram to identify and quantify the compounds (f).
What are the phases of HPLC?
There are two phases for HPLC: the mobile phase and the stationary phase. The mobile phase is the liquid that dissolves the target compound. The stationary phase is the part of a column that interacts with the target compound.
Can HPLC be used to analyze compounds?
Only compounds dissolved in solvents can be analyzed with HPLC. HPLC separates compounds dissolved in a liquid sample and allows qualitative and quantitative analysis of what components and how much of each component are contained in the sample.
When was HPLC first used?
The first 6,000-psi HPLC devices were introduced in 1972 , and the addition of septumless injectors evolved the “P” in HPLC from “pressure” to “performance.”. During the 1980s, chromatographers developed new separation methods and detectors to improve and expand the usability of HPLC into a variety of applications.
How does HPLC work?
HPLC employs a mobile phase, forced by high pressure (6,000-9,000 psi) through a column. A liquid sample is introduced into a thin, stainless steel column, traveling through vacuum-tight connectors that sustain high pressure throughout the system. Columns are packed with tiny particles of a stationary phase that are porous and/or interact chemically with sample components to separate them. When the separated components exit the column, scientists can use a detecting device — mass spectrometer, evaporative light scattering, refractive index and others — to quantitatively analyze the components.
When was the first liquid chromatography?

Why was HPLC poised to catch on with scientists at that fateful Las Vegas meeting?
HPLC was poised to catch on with scientists at that fateful Las Vegas meeting because there were applications—drug discovery and biological separations, among others—where leading separation methods such as GC just weren’t getting the job done.
What instrument did Horváth use to separate biological molecules?
In fact, he called his instrument a nucleic acid analyzer.

How does HPLC work?
In HPLC, a liquid mobile phase carries mixtures of compounds through a column packed with particles. As a pump forces the mobile phase through the column, the compounds interact with the stationary phase—the particles’ surface—to different degrees and are separated in the process.
