What you need to know about HPLC?
HPLC is a chromatographic technique that separates a mixture of compounds into its constituent components in order to identify, quantify, and purify them. It does this by separating those components based on their polarity. While polar compounds mix well with other polar compounds, nonpolar compounds do not.
What information does HPLC provide?
High-performance liquid chromatography (HPLC) is an analytical technique to separate, identify, and quantify components in a mixture. It is the single biggest chromatography technique essential to most laboratories worldwide.
What is the most important part of HPLC?
The infusion pump is one of the most important components of the HPLC system. Infusion pumps are classified into constant pressure pumps and constant flow pumps according to the factors of constant output liquid.
What is the importance of HPLC?
HPLC is the form of liquid chromatography that is generally used in the pharmaceutical industry, as it can provide the precise results that are required. The results can be used to analyse finished drug products and their ingredients quantitatively and qualitatively during the manufacturing process.
Who invented the HPLC?
The first commercially available HPLC system, the ALC100 HPLC, was developed by Waters Associates (now Waters Corporation), a company offering analytic tools and systems to scientists, in 1967. By the 1980s, HPLC was being commonly used in the world of science.
Why is it called HPLC?
High-performance liquid chromatography (HPLC), formerly referred to as high-pressure liquid chromatography, is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture….High-performance liquid chromatography.

What does HPLC stand for?
High-performance liquid chromatography
High-performance liquid chromatography (or high-pressure liquid chromatography, HPLC) is a chromatographic technique that can separate a mixture of compounds and is used in biochemistry and analytical chemistry to identify, quantify and purify the individual components of the mixture.
Who invented HPLC?
How many detectors are there in HPLC?
They are of three types, i.e. fixed wavelength detectors, variable wavelength detectors and the diode array detectors.
How many pumps are in HPLC?
There are three main types of HPLC pumps. Most HPLC pumps are reciprocating pumps. The solvent is drawn into a small chamber (with the solvent check valve open) and pumped out of it (when the column check valve is open) by the back and forth motion of a motor driven piston.
What are other uses for HPLC?
HPLC has been used for manufacturing (e.g., during the production process of pharmaceutical and biological products), legal (e.g., detecting performance enhancement drugs in urine), research (e.g., separating the components of a complex biological sample, or of similar synthetic chemicals from each other), and medical …
How long has HPLC been around?
What is HPLC and how does it work?
HPLC is an analytical technique used to separate, identify or quantify each component in a mixture. HPLC works following the basic principle of thin layer chromatography or column chromatography , where it has a stationary phase and a mobile phase.
What are the advantages and the disadvantages of HPLC?
HPLC and Similar Techniques. Like other forms of chromatography,HPLC allows the separation of chemical constituents through the use of a mobile phase and a stationary phase.
What is basic principle of HPLC?
HPLC Theory. HPLC works following the basic principle of thin layer chromatography or column chromatography, where it has a stationary phase ( solid like silica gel) and a mobile phase (liquid or gas). The mobile phase flows through the stationary phase and carries the components of the mixture with it.
What is the difference between HPLC and HPTLC?
HPLC is high-pressure liquid chromatography or high-performance liquid chromatography while HPTLC is high-performance thin-layer chromatography. Another major difference between HPLC and HPTLC is that HPLC is a type of column chromatography while HPTLC is a type of planar chromatography.
