Negative blood group | Facts and Problems

Negative blood group is one where the red blood cells lack Rhesus antigen on their surfaces. As we know, there are of 4 types of blood groups broadly like A, B, AB & O group in humans. These are classified based on the presence of respective antigens on the RBC surface. Similarly, there is one […]

Red blood cells Structure | Their Source and Functions

Red blood cells Structure

Red blood cells are major cells of liquid connective tissue blood. The blood is red in color due to the abundance of these cells in it. However, unlike other body cells, they lack the essential cell organelles including nucleus. Hence, these are also called as blood corpuscles. Red blood cells Structure The blood corpuscles as […]

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 […]

Who Invented Television | Its Advantages & Disadvantages to Man

who invented television

Television is a wonderful invention of the past century. There were many contributors to its invention. But to the question who invented television, you can say it was J.L Baird (in full John Logie Baird). He did a lot of advancements in the outcome of the TV with movable images which were not existent till his invention. Television once considered a luxury is […]

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 […]
