What is 'analytical centrifugation' 🧑‍🔧

In this article, I'd like to discuss "What is 'analytical centrifugation'". Let's look at what it is and how to respond to some frequently asked questions.

I will start with a more simple explanation:

Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed.

A short answer to this question is…

Centrifugation following precipitation to separate solids from solid-liquid suspensions; faster than filtration.

It is a separation method where components of a sample are separated on the basis of their density in a centrifuge according to the centrifugal force they experience.

Analytical centrifuges are the ultracentrifuges that are used for the analysis of various particles present in the sample.

Analytical ultracentrifugation (AUC) is a versatile and robust method for the quantitative analysis of macromolecules in solution

Analytical centrifugation is a method of studying the hydrodynamic properties of a molecule as it moves through a fluid medium.

Hydrodynamic behavior depends on mass, density, and shape, so one can study these properties of a molecule by accelerating a sample preparation in a centrifugal field.

Do you know what makes people curious? Here are a few questions and answers:

Analytical centrifugation

What is meant by the term velocity centrifugation...

It refers to the velocity centrifugation, where the separation of the particles occurs based on their sedimentation rate that directly depends upon the particle mass or size. The particles’ shape also influences the rate of sedimentation. It makes the use of a high-density sucrose solution of 5-20% to create a density gradient.

What are the different types of centrifugation methods...

Based on the particle separation, there are two significant types of centrifugation methods: Preparative centrifugation: It is a technique concentrating one component from the other. Analytical centrifugation: It is a method that measures the physical, chemical and hydrodynamic properties of the suspended molecules.
