Hplc Mobile Phase: Requirement and precautions.

In High-performance liquid chromatography (HPLC) method, the mobile phase is of prime importance. It is the component which takes the actual process of separation under the influence of pressure over the stationary phase. The HPLC mobile phase is a bit of concern in comparison to mobile phase of other chromatography techniques due to the following reasons. ♠ […]

HPLC Applications | In Diagnosis, Research & Industry

HPLC Applications

HPLC (high-performance liquid chromatography) is one of the advanced types of chromatography. It is highly sophisticated and expensive tools in the present analytical chemistry. It is given prominent importance due to its attributes like High sensitivity, i.e., the ability to evaluate samples of very minute concentrations like in nano-gram and picogram Detect precisely chemically similar molecules like […]

10 Types of Chromatography | Based on Different Techniques & Methods

Types of Chromatography

There are many types of chromatography like HPLC, Gas chromatography, paper chromatography, thin layer chromatography, etc. Chromatography is an analytic technique which is based on the separation of molecules of a sample over two phases. These phases are called as the stationary and the mobile phase. Initially, it was developed as column chromatography. But its […]

What is Chromatography? Its Definition, Principle & Uses

What is chromatography

What is Chromatography? Chromatography is derived from Greek terms “chromo= color & gram=bands.” Hence as the name indicates, in chromatography, there is the formation of colored bands. These bands are indicative of different components in the sample. In the Initial stages, it was developed as column chromatography to separate mixtures. Here into a long vertical column, sample along with a mobile phase was allowed […]

What is HPLC GRADE & its importance in HPLC ?

High pressure liquid chromatography is one of the widely used analytical technique. But it very sensitive to operate at constant pressure. Further the mobile phase passes through a dense column so all the material used in the procedure should be of high quality. While performing analysis by HPLC chromatography, one is advised to use HPLC […]

Chromatography Lab: Minimal and essential requirements

Chromatography lab

Chromatography labs vary largely based on the type of  chromatography method used. They are designed in a way suitable for the particular chromatographic procedure. But all the chromatography labs have some common requirements to ensure the sensitivity, reproducibility and reliability in analytical results. Since chromatographic procedure is one of the mandatory requirement in some researches, it is necessary to provide a […]
